Java is an object-oriented, portable, and robust programming language ideal for versatile software development, whereas PHP is focused on web scripting. To start programming in Java, one must install the Java Development Kit (JDK) and use a text editor or IDE to write and compile code. Java has a strict syntax and requires programs to be structured around classes and methods.

1. JAVA
PROGRAMMING
Java: Object-oriented, portable,
robust language. Rich library, multi-
threading support. Ideal for
versatile software development,
prioritizing portability and reliability.
JAVA PHP
Java: Portable, robust,
versatile. PHP: Web
scripting, dynamic
development. Different
strengths: Java for general-
purpose, PHP for web-
focused tasks.
JAVA C++
Java: Portable, robust,
versatile. C++: High
performance, system-
level control. Java for
diverse apps, C++ for
efficiency and control.
Setup
Install the Java Development Kit
(JDK) on your system. It includes the
Java compiler (javac) and Java
Runtime Environment (JRE).
Write Code
Use a text editor or an Integrated
Development Environment (IDE)
like Eclipse or IntelliJ IDEA to write
Java code. Save files with a .java
extension.
Syntax
Java has a strict syntax. A program
starts with a class containing a main
method. Statements end with
semicolons.
Compile
Use the javac command to compile
your .java files into bytecode .class files:
javac YourProgram.java
Run
Execute the compiled program using
the java command
java YourProgram
Java programming involves writing code using
the Java language to create software
applications. To work with Java
