I have tried this Snape problem and have been using JAVA, but NZEC Runtime error is being displayed while submitting the code. I am attaching my code, please let me know the mistake, I have been trying different methods but the result is same.

import java.util.ArrayList;
import java.util.Scanner;
import java.util.StringTokenizer;

class Snape {

	static ArrayList<Double> arr= new ArrayList<Double>(); //using for adding the input numbers into an array
	static ArrayList<String> inputs = new ArrayList<String>(); // using this for the number of testcases
	
	static void doThis(String s )
	{
		int l=0,m = 0;	
		StringTokenizer st = new StringTokenizer(s); //breaking the line e.g 10 15 using spaces in order to get 10 and 15 as different integers
			
			while(st.hasMoreTokens())
			{
                             try{
				l = Integer.parseInt(st.nextToken());
				m = Integer.parseInt(st.nextToken());
                               }
                              catch(Exception e)
                               {
                                     return;
                                }
			}
			float z = l*l+m*m;
			float d = m*m-l*l;
			double max = Math.sqrt(z);
			double min = Math.sqrt(d);
			
			arr.add(min);
			arr.add(max);
	}
	
	public static void main(String[] args) {
		int test=0;
		Scanner sc1 = new Scanner(System.in);
		Scanner sc = new Scanner(System.in);

		test = sc1.nextInt();
		while(test>0)
		{
			inputs.add(sc.nextLine());
			test--;
		}
		int noOfTest = inputs.size();
		for(int i =0;i<noOfTest;i++)
			doThis(inputs.get(i));
		int n = arr.size();
		boolean b = true;
		int i =0;
		while(i<n)
		{
			System.out.println(arr.get(i)+" "+arr.get(i+1));
			i=i+2;
		}
	}
