Description

The java.lang.Math.abs(int a) returns the absolute value of an int value. If the argument is not negative, the argument is returned. If the argument is negative, the negation of the argument is returned. Note that if the argument is equal to the value of Integer.MIN_VALUE, the most negative representable int value, the result is that same value, which is negative.

Declaration

Following is the declaration for java.lang.Math.abs() method

public static int abs(int a)

Parameters

  • a -- the argument whose absolute value is to be determined

Return Value

This method returns the absolute value of the argument.

Exception

  • NA

Example

The following example shows the usage of lang.Math.abs() method.

package com.tutorialspoint;

import java.lang.*;

public class MathDemo {

   public static void main(String[] args) {

      // get some integers to find their absolute values
      int x = 175;
      int y = -184;

      // get and print their absolute values
      System.out.println("Math.abs(" + x + ")=" + Math.abs(x));
      System.out.println("Math.abs(" + y + ")=" + Math.abs(y));
      System.out.println("Math.abs(-0)=" + Math.abs(-0));
   }
}

Let us compile and run the above program, this will produce the following result:

Math.abs(175)=175
Math.abs(-184)=184
Math.abs(-0)=0
