How do you create a shape in an applet?

In this article we will draw a ellipse on Java applet by two ways. By using the drawOval(int x, int y, int width, int height) or by using mathematical formula (X= A * sin a, Y= B *cos a, where A and B are major and minor axes and a is the angle ). Similarly, we will draw a rectangle on Java applet by two ways.

How do I run an applet program?

There are two standard ways in which you can run an applet:

How do you reverse a number in Java?

Example 1: Reverse a Number using a while loop in Java

  1. First, the remainder of the num divided by 10 is stored in the variable digit.
  2. After second iteration, digit equals 3, reversed equals 4 * 10 + 3 = 43 and num = 12.
  3. After third iteration, digit equals 2, reversed equals 43 * 10 + 2 = 432 and num = 1.
