I need hint for exercise

Read numbers from keyboard and calculate their total until the user enters the word «total». Display to the screen the total.

public class Solution { public static void main(String[] args) throws Exception { BufferedReader reader = new BufferedReader(new InputStreamReader(System.in)); int sum = 0; String number = reader.readLine(); int one = Integer.parseInt(number);

```    while(number != "total") {
sum += one;
if(number == "total") {
System.out.print("total is : " + sum);
break;
}
}
}
```

}

There is some problem with your formatting, and I didn't try to understand all your code, but one mistake that is immediately apparent:

if(number == "total") can never be true, because in the while condition two lines above you make sure to enter that part of the code only, if number and total are different! (so they can not be the same two lines later)

```import java.io.BufferedReader;

public class Solution {
public static void main(String[] args) throws Exception {
int sum = 0;
do {//I use do-while loop
System.out.print("Insert a number or write total: ");//let know the user what to do
String number = reader.readLine();//this line has to be inside the do-while loop
if (number.equals("total")) { //the correct method is equals not "=="
System.out.print("total is : " + sum);
break;
}
int one = Integer.parseInt(number);
sum += one;
} while (true);//break keyword stops the loop
}
}
```
