ATM : Getting wa

import static java.lang.Math.abs;
import java.util.Scanner;
class Sample1 {
public static void main(String[] args){
Scanner scan = new Scanner(;
double per = scan.nextDouble();
float s =0.50f;
double a=120.00,b;
b = abs(per-120.00);



Convert the number to string and try formatting the string using the below code. ("%.2f" is for 2 decimal places)
String st = String.valueOf(a);
String str=String.format("%.2f",st);

Refer this.
