Java Fundamentals Quiz

Java Interface

• A Java interface is a collection of abstract methods and constants that define a contract that must be implemented by any class that implements it.
• An interface is essentially a blueprint of a class, and it specifies a set of methods that must be implemented by any class that implements it.
• Interfaces are used to achieve abstraction and multiple inheritance in Java.

Fundamental Operations in Java

• The fundamental operations in Java include arithmetic, assignment, comparison, logical, and bitwise operations.
• Arithmetic operations include addition, subtraction, multiplication, and division, as well as modulus and increment/decrement operations.
• Assignment operations include simple assignment, addition assignment, subtraction assignment, and so on.
• Comparison operations include equal, not equal, greater than, less than, and so on.
• Logical operations include AND, OR, and NOT.
• Bitwise operations include AND, OR, and XOR.

Java Applet

• A Java applet is a small Java program that runs on a web browser, typically used to provide interactive features on a web page.
• Applets are compiled into an intermediate form called bytecode, which can be run on any platform that has a Java Virtual Machine (JVM) installed.
• Java applets were widely used in the early days of the web, but have since been largely replaced by other technologies such as JavaScript and HTML5.
