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 wrapper class?
Everything in java is an object, except primitives. Primitives are int, short, long, boolean, etc. Since they are not objects, they cannot return as objects, and collection of objects. To support this, java provides wrapper classes to move primitives to objects. Some of the wrapper classes are Integer, Long, Boolean, etc.
Famous Quotations
Success consists of going from failure to failure without loss of enthusiasm.
-- Winston Churchill
