Solution
1.Object oriented programming is the background for java
2.java platform are
Standard edition
Enterprise edition
Oracle standard edition 8 is currently used moreover and hence we use the same here.
3.issues during installation
4.environment variable is a string which sets them to the current environment.
In windows
5.the class path is given or set by the following command
Set CLASSPATH =path1;path3;
6.using home environment variable helps for easy update of the JDK.
7.class ,objects
Encapsulation,inheritance, polymorphism
8.inheritance is used to derive any data from base class to the derived class
9.Both polymorphism and inheritance uses the concept of super class and sub class but they
differ in just a small aspect that polymorphism is used to change the aspect of super class while
inheritance is used to develop or extent the behavior of super class
10.java programs main advantage is the byte code.Bytecode makes the java platform
independent.Java program is converted in to bytecode which can be run anywhere.
11.JVM is the java virtual machine which is a abstract computing machine that enables computer
to run java program.
12.java application is just like program that run in our computer but the java applet are runned in
the web browser and it is downloaded from the web server when it is needed.
13.java classes
Java classes consist of variable and methods.
Java method:
Java method is the set of code within a curly braces which perform a certain task.
Main method must be available in any of the classes of al.

JAVA ITCS 1213 Self-check Quiz Interfaces 1) What is an interface comp.docxolsenlinnea427
JAVA ITCS 1213 Self-check Quiz Interfaces
1) What is an interface comprised of in Java 7?
2) Can an interface have fields?
3) What is the access of all the methods in a Java interface?
4) Can an interface be instantiated?
5) Give two reasons for interfaces in the Java language.
6) How many interfaces can another class implement?
7) What does it mean to implement a Java interface?
8) If a class extends an Employee class and implements a Comparable interface, what are the is-a relationships established?
9) How many classes can a given class extend?
10) Name five Java pre-written interfaces.
Solution
Multiple Questions : Answering 6 Questions.
1) What is an interface comprised of in Java 7?
An interface is a reference type in Java, it is similar to class, it is a collection of abstract methods. A class implements an interface, thereby inheriting the abstract methods of the interface.
Along with abstract methods an interface may also contain constants, default methods, static methods, and nested types. Method bodies exist only for default methods and static methods.
4) Can an interface be instantiated?
You cannot instantiate an interface.
6) How many interfaces can another class implement?
A class can implement more than one interface at a time.
7) What does it mean to implement a Java interface?
When a class implements an interface, you can think of the class as signing a contract, agreeing to perform the specific behaviors of the interface. If a class does not perform all the behaviors of the interface, the class must declare itself as abstract.
A class uses the implements keyword to implement an interface. The implements keyword appears in the class declaration following the extends portion of the declaration.
9) How many classes can a given class extend?
A Java class can only extend one parent class. Multiple inheritance is not allowed.
10) Name five Java pre-written interfaces.
java.lang.Runnable
java.util.concurrent.Callable
java.io.FileFilter
java.util.Comparator
java.beans.PropertyChangeListener

Need for Speed: Removing speed bumps from your Symfony projects ⚡️Łukasz Chruściel
No one wants their application to drag like a car stuck in the slow lane! Yet it’s all too common to encounter bumpy, pothole-filled solutions that slow the speed of any application. Symfony apps are not an exception.
In this talk, I will take you for a spin around the performance racetrack. We’ll explore common pitfalls - those hidden potholes on your application that can cause unexpected slowdowns. Learn how to spot these performance bumps early, and more importantly, how to navigate around them to keep your application running at top speed.
We will focus in particular on tuning your engine at the application level, making the right adjustments to ensure that your system responds like a well-oiled, high-performance race car.
