Sum Until Condition in Java: Explanation & Practice

Problem summary

Calculate sum of natural numbers until sum exceeds a limit.

Starter code

public class Main {
    public static void main(String[] args) {
        int limit = 20; // Test case 1
        
        // Sum 1+2+3+... until sum > limit
        // Print: Sum: <sum>, Count: <how many numbers added>
    }
}

Expected output and test cases

• 1+2+3+4+5+6=21 > 20

  Sum: 21, Count: 6

• 1+2+3+4=10 > 9

  Sum: 10, Count: 4

• Sum to 10 numbers > 50

  Sum: 55, Count: 10

Hints

1. Use while loop with sum <= limit condition
2. Increment counter each iteration
3. Add counter to sum before checking
