Question about the task

Under discussion

public class Solution { public static void main(String[] args) throws Exception { BufferedReader reader = new BufferedReader(new InputStreamReader(System.in)); int sum = 0; boolean isExit = false; while(true) { String s = reader.readLine(); if(s.equals("sum")) { System.out.println(sum); return; } } } }

Use the keyboard to enter numbers and calculate their sum until the user enters the word "sum".
Display the resulting sum on the screen.

Hint: to read from the keyboard until the string 'exit' is input, do this:

BufferedReader buffer = new BufferedReader(new InputStreamReader(System.in));
while (true)
{
	String s = buffer.readLine();
	if (s.equals("exit"))
		break;
}

Requirements:

The program must read data from the keyboard.
The program should stop reading data from the keyboard after the user enters the word "sum" in lowercase letters and presses Enter.
The program should work correctly if the user enters one number and the word "sum".
The program should work correctly if the user enters two numbers and the word "sum".
The program should work correctly if the user enters more than two numbers and the word "sum".
The program should display text on the screen.

import java.util.Scanner; /* Console-based piggy bank */ public class Solution { public static void main(String[] args) throws Exception { ArrayList<Integer>list=new ArrayList<Integer>(); Scanner s=new Scanner(System.in); int sum=0; while(true){ String a=s.nextLine(); if (a.equalsIgnoreCase("sum")){ break; } sum=sum+Integer.parseInt(a); } System.out.println(sum); } } Here is my code without using arraylist

You have to make use of arraylist. Happy coding!!

you are not adding the inputs to the variable "sum"
