Is there a way to simplify this code which aims to return an absolute value given an integer?

Is there a way to simplify this piece of code further? The codes aim is to return an absolute value given an integer.

public class Abs {
public static int abs(int x) {
if(x < 0) { return -x; }
if(x >= 0) { return x; }
assert false;
return 0;
}
}

You can use the ternary operator to simplify the code

public class Abs {
   public static int abs(int x) {
     return x < 0 ? -x : x;
   }
}

You could put this in an integer and check the condition when you assign a value. int y = x < 0 ? -x : x; Or in a method:

public static int abs(int x) {
return x < 0 ? -x : x;
}

The "assert false" will never be reached, so it is useless.
