# Example of Math.abs() in Java

UPDATED: 31 December 2015

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.
Also Math.abs(long a), Math.abs(float a) and Math.abs(double a) is available in java.lang.Math class.

public static void main(String[] args) {
int x = 1, y = -2;

System.out.println("Before:");
System.out.println("x = " + x + ", y = " + y);

/**

*
* Math.abs(int a) => return 'int'
* Math.abs(long a) => return 'long'
* Math.abs(float a) => return 'float'
* Math.abs(double a) => return 'double'
*/
x = Math.abs(x);
y = Math.abs(y);

System.out.println("After:");
System.out.println("x = " + x + ", y = " + y);
}
}
```

Output
```Before:
x = 1, y = -2
After:
x = 1, y = 2
```
