Program: How to get absolute value in java?

In mathematics, the absolute value (or modulus) |a| of a real number a is the numerical value of a without regard to its sign. So, for example, the absolute value of 3 is 3, and the absolute value of -3 is also 3. The absolute value of a number may be thought of as its distance from zero. Below example shows how to get absolute value using Math.abs() method.

package com.java2novice.math;

public class MyAbsEx {

	public static void main(String[] args) {
		
		double a = -23.45;
		int b = 234;
		double c = 12.54;
		System.out.println("absolute value of a: "+Math.abs(a));
		System.out.println("absolute value of b: "+Math.abs(b));
		System.out.println("absolute value of c: "+Math.abs(c));
	}
}

absolute value of a: 23.45
absolute value of b: 234
absolute value of c: 12.54
