Java Math.abs(arg) return absolute value of argument.
Java Math.abs return positive value of the argument. argument can be positive or negative
if argument is Infinity Math.abs() will return Positive Infinity.
If the argument is NaN Math.abs will return NaN.
If the argument is equal to the Integer.MIN_VALUE or Long.MIN_VALUE the most negative representable int value or long value. Java Math.abs will return that same value which is negative.

Example 1

public class Program{

     public static void main(String []args){
        int x=-5;
        int y=10;
        System.out.println("Math.abs(x) : "+Math.abs(x));
        System.out.println("Math.abs(y) : "+Math.abs(y));
        System.out.println("Math.abs(Integer.MIN_VALUE) : "+Math.abs(Integer.MIN_VALUE));
     }
}

Math.abs(x) : 5
Math.abs(y) : 10
Math.abs(Integer.MIN_VALUE) : -2147483648

Example 2

public class Program{

     public static void main(String []args){
        double x=-5.67;
        double y=10.45;
        System.out.println("Math.abs(x) : "+Math.abs(x));
        System.out.println("Math.abs(y) : "+Math.abs(y));
        System.out.println("Math.abs(15.7/0) : "+Math.abs(15.7/0));
        System.out.println("Math.abs(15/2) : "+Math.abs(15/2));
        System.out.println("Math.abs(15.0/2) : "+Math.abs(15.0/2));
        System.out.println("Math.abs(15/2.0) : "+Math.abs(15/2.0));
        System.out.println("Math.abs(14.0/2) : "+Math.abs(14.0/2));
        System.out.println("Math.abs(14/2.0) : "+Math.abs(14/2.0));
     }
}

Math.abs(x) : 5.67
Math.abs(y) : 10.45
Math.abs(15.7/0) : Infinity
Math.abs(15/2) : 7
Math.abs(15.0/2) : 7.5
Math.abs(15/2.0) : 7.5
Math.abs(14.0/2) : 7.0
Math.abs(14/2.0) : 7.0

Example 3

public class Program{

     public static void main(String []args){
        float x=-5.67f;
        float y=10.45f;
        System.out.println("Math.abs(x) : "+Math.abs(x));
        System.out.println("Math.abs(y) : "+Math.abs(y));
        System.out.println("Math.abs(15.7f/0) : "+Math.abs(15.7f/0));
        System.out.println("Math.abs(15/0f) : "+Math.abs(15/0f));
        System.out.println("Math.abs(15/2) : "+Math.abs(15/2));
        System.out.println("Math.abs(15f/2) : "+Math.abs(15f/2));
        System.out.println("Math.abs(15/2f) : "+Math.abs(15/2f));
        System.out.println("Math.abs(14f/2) : "+Math.abs(14f/2));
        System.out.println("Math.abs(14/2f) : "+Math.abs(14/2f));
     }
}

Math.abs(x) : 5.67
Math.abs(y) : 10.45
Math.abs(15.7f/0) : Infinity
Math.abs(15/0f) : Infinity
Math.abs(15/2) : 7
Math.abs(15f/2) : 7.5
Math.abs(15/2f) : 7.5
Math.abs(14f/2) : 7.0
Math.abs(14/2f) : 7.0
