Program: Example for Math.signum() method.


Description:

Math.signum() function returns zero if the passed argument is zero, 1.0 if the passed argument is greater than zero, -1.0 if the passed argument is less than zero.


Code:
package com.java2novice.math;

public class MySignumEx {

	public static void main(String a[]){
		
		System.out.println("signum value of 20.23 is: "+Math.signum(20.23));
		System.out.println("signum value of 0 is: "+Math.signum(0));
		System.out.println("signum value of -20.23 is: "+Math.signum(-20.23));
	}
}

Output:
signum value of 20.23 is: 1.0
signum value of 0 is: 0.0
signum value of -20.23 is: -1.0

What is adapter class?
An adapter class provides the default implementation of all methods in an event listener interface. Adapter classes are very useful when you want to process only few of the events that are handled by a particular event listener interface. You can define a new class by extending one of the adapter classes and implement only those events relevant to you.
