Answer 2

Java programs are often asked in an interview. These programs can be asked from check statements, array, string, oops etc. Basic Java programs like fibonacci series, prime numbers, factorial numbers and palindrome numbers are often asked in interviews and exams. All these programs are listed with the maximum number of examples and outputs.

Java is a general-purpose, class-based, object-oriented programming language designed to have fewer implementation dependencies. It is a computing platform for application development. Java is therefore fast, secure and reliable. It is widely used to develop Java applications in notebooks, data centers, game consoles, scientific supercomputers, mobile phones, etc.

Code of the given question:

import java.awt.*;

import java.awt.event.*;

import java.applet.*;
