JRE , JDK and platform independent nature of JAVA
Java programming language was originally developed by Sun Microsystems which was initiated by James Gosling and released in 1995 as core component of Sun Microsystems.
JRE stands for Java Runtime Environment which is used to provide an environment at runtime.
JVM or Java Virtual Machine is the medium which compiles Java code to bytecode which gets interpreted on a different machine and hence it makes it Platform/ Operating system independent.
JDK (Java SE Development Kit) Includes a complete JRE (Java Runtime Environment) plus tools for developing, debugging, and monitoring Java applications.
Java -lec-1
Java is an object-oriented programming language that is platform independent. It compiles to bytecode that runs on a Java Virtual Machine (JVM) available for most operating systems. Key features of Java include being object-oriented, compiled and interpreted, platform independent, distributed, multi-threaded, dynamic, and robust/secure. The Java Development Kit (JDK) includes tools like compilers while the Java Runtime Environment (JRE) contains libraries and the JVM needed to run Java applications. Integrated development environments (IDEs) provide tools to write and test Java code.

Introduction to Java Programming
Java was developed by Sun Microsystems in 1991 as a simple yet robust programming language. It is an object-oriented language that allows for abstraction, encapsulation, inheritance, and polymorphism. To compile and run a Java program, developers write code in an editor, save it with a .java extension, compile it to generate a .class file using javac, and execute the bytecode using java without specifying the file extension. The Java Virtual Machine then interprets and executes the bytecode, allocating memory and threads as needed.
Java presentation
Java is an object-oriented programming language and platform. It was developed at Sun Microsystems in 1995 to be portable and high-performance. Java applications can run on many systems without recompilation because it uses a virtual machine that translates bytecode into native machine code. The key components of Java are the JVM (Java Virtual Machine), JRE (Java Runtime Environment), and JDK (Java Development Kit). The JVM executes Java bytecode, while the JRE provides libraries and tools for developing Java applications. The JDK is a superset of the JRE and includes development tools like compilers and debuggers.
JVM
This document provides an overview of the Java Virtual Machine (JVM) and how it executes Java code. It describes that the JVM converts Java bytecode into machine language and executes it, allowing Java programs to run on different platforms. It also outlines the key components of the JVM, including the class loader, execution engine, stack, method area, and garbage collected heap.

Internal working JVM
The document discusses the differences between JDK, JRE, and JVM. It states that JDK includes development tools like compilers and debuggers, while JRE only allows running Java programs and does not include development tools. JVM is contained within both JDK and JRE and is responsible for executing Java programs line by line. The document then discusses the internal working of JVM, stating that it behaves as a runtime engine and calls the main method. When a Java program runs, the class files are loaded by the class loader and the bytecodes are saved in the method area. The JVM then produces class objects and uses the stack and registers to execute instructions.

What is Java
Java is a programming language and a platform. Java is a high level, robust, object-oriented and secure programming language. It was originally developed by Sun Microsystems which was initiated by James Gosling and released in 1995 as core component of Sun Microsystems' Java platform (Java 1.0 [J2SE]).
The latest release of the Java Standard Edition is Java SE 10. With the advancement of Java and its widespread popularity, multiple configurations were built to suit various types of platforms. For example: J2EE for Enterprise Applications, J2ME for Mobile Applications.
The new J2 versions were renamed as Java SE, Java EE, and Java ME respectively. Java is guaranteed to be Write Once, Run Anywhere.
Java String
In Java, String is basically an object that represents sequence of char values. An array of characters works same as Java string. In Java programming language, strings are treated as objects. The Java platform provides the String class to create and manipulate strings.
Exception in Java
An exception is an unwanted or unexpected event, which occurs during the execution of a program i.e at run time, that disrupts the normal flow of the program’s instructions.
Exception is an abnormal condition.In Java, an exception is an event that disrupts the normal flow of the program. It is an object which is thrown at runtime.
What is Exception Handling
Exception Handling is a mechanism to handle runtime errors such as ClassNotFoundException, IOException, SQLException, RemoteException, etc.
Collections in Java
The Collection in Java is a framework that provides an architecture to store and manipulate the group of objects.
Java Collections can achieve all the operations that you perform on a data such as searching, sorting, insertion, manipulation, and deletion.
Java Collection means a single unit of objects. Java Collection framework provides many interfaces (Set, List, Queue, Deque) and classes (ArrayList, Vector, LinkedList, PriorityQueue, HashSet, LinkedHashSet, TreeSet).
The Java Collections Framework is a collection of interfaces and classes which helps in storing and processing the data efficiently. This framework has several useful classes which have tons of useful functions which makes a programmer task super easy.

What is Spring
Spring is a lightweight framework and an open source Java platform that provides comprehensive infrastructure support for developing robust Java applications very easily and very rapidly. Spring framework was initially written by Rod Johnson and was first released under the Apache 2.0 license in June 2003. This tutorial has been written based on Spring Framework version 4.1.6 released in Mar 2015. It can be thought of as a framework of frameworks because it provides support to various frameworks such as Struts, Hibernate, Tapestry, EJB, JSF, etc. The framework, in broader sense, can be defined as a structure where we find solution of the various technical problems.
The Spring framework comprises several modules such as IOC, AOP, DAO, Context, ORM, WEB MVC etc. We will learn these modules in next page. Let's understand the IOC and Dependency Injection first.
Web Service
A web service is any piece of software that makes itself available over the internet and uses a standardized XML messaging system. XML is used to encode all communications to a web service. For example, a client invokes a web service by sending an XML message, then waits for a corresponding XML response. As all communication is in XML, web services are not tied to any one operating system or programming language java can talk with Perl; Windows applications can talk with Unix applications.
Web Services tutorial is designed for beginners and professionals providing basic and advanced concepts of web services such as protocols, SOAP, RESTful, java web service implementation, JAX-WS and JAX-RS tutorials and examples.
Web service is a technology to communicate one programming language with another. For example, java programming language can interact with PHP and .Net by using web services. In other words, web service provides a way to achieve interoperability.
Web services are self-contained, modular, and distributed.

1. Java is a popular object-oriented programming language created by James Gosling at Sun Microsystems in 1991.
2. The Java Development Kit (JDK) provides tools for developing Java programs, and includes the Java Runtime Environment (JRE) which allows programs to run on any platform with a Java Virtual Machine (JVM).
3. Key features of Java include being platform independent, secure, robust, and multithreaded. Java code is compiled to bytecode that runs on a JVM, allowing the same code to run on different operating systems.

How to Make a Field Mandatory in Odoo 17
In Odoo, making a field required can be done through both Python code and XML views. When you set the required attribute to True in Python code, it makes the field required across all views where it's used. Conversely, when you set the required attribute in XML views, it makes the field required only in the context of that particular view.

What is java
- 1. Java, was developed by Sun Microsystems, by James Gosling, is an object oriented programming language.
- 2. Java, was developed by Sun Microsystems, by James Gosling, is an object oriented programming language. Now oracle has taken over sun Microsystems, so all the products of sun comes under Oracle license. Now Java has become more than a language as time passed. It is a platform because it has its own Runtime environment, has open source API, distributed programming through RMI. It may look like very unclear but you will feel better after started learning Java.
- 3. First and foremost Java is an object oriented programming language. Object oriented means we have to develop software collection of distinct objects. There is a famous saying about Java: WORA (Write Once Run Anywhere). Java are saved in any editor (e.g.: notepad, notepad++) with java extension. These source codes are then compiled using Java compiler which converts it into Java byte code , and then byte code is executed using the Java Virtual Machine (JVM). Both java compiler and Java Virtual Machine are the part of java development kit.
- 4. Java Byte Code is a code which is stored in a separate .class file which is created after compiling your source code. We can run this byte code on different- different operating systems by using their specific JRE. In other words we can say Java is platform dependent in case of JRE.
- 5. Java Software Development Kit (Java SDK) The Java SDK (Software Development Kit) is the complete package to develop any java software. It has many tools in bin folders; like Javac, Javap, javadoc, java etc. It is the combination of JRE and other library tools. Java Runtime Environment (JRE) For executing any compiled class, Java Runtime Environment provides a runtime environment for it. It is the combination of JVM (Java Virtual Machine) plus other libraries. It reads the code line by line and executex the code.
- 6. Java Code Conventions As per the oracle standard, to write code as per the naming convention is a good programming practice. Naming conventions are given for class, package, function, variable etc are to be followed. Java Applets Java Applet is a program which executes and runs on web browser. To run an applet browser must have enable Java plugin.
