The abs() method is used to calculate absolute values.

In Core Java, the Math.abs() method is used to calculate the absolute value of a number. The abs() method returns the absolute value of its argument, which is the distance of the argument from zero. Here’s an example:

java

public class AbsoluteValueExample {

    public static void main(String[] args) {

        int number = -10;

        double decimalNumber = -15.5;
        int absoluteInt = Math.abs(number);

        double absoluteDouble = Math.abs(decimalNumber);

System.out.println("Absolute value of " + number + " is: " + absoluteInt); System.out.println("Absolute value of " + decimalNumber + " is: " + absoluteDouble); } }

In this example, Math.abs() is used for both integers and doubles to obtain their absolute values. The output will be:

Absolute value of -10 is: 10

Absolute value of -15.5 is: 15.5
