Calculate Power in Java: Explanation & Practice

Problem summary

Write a program that calculates base^exponent using a loop. Do NOT use Math.pow().

Starter code

public class Main {
    public static void main(String[] args) {
        int base = 2;
        int exponent = 10; // Test case 1
        
        // Calculate base^exponent using a loop (no Math.pow)
        // Print: Result: <result>
    }
}

Expected output and test cases

• 2^10 = 1024

  Result: 1024

• 3^4 = 81

  Result: 81

• 5^0 = 1

  Result: 1

Hints

1. Start with result = 1
2. Multiply by base, exponent number of times
3. Handle exponent = 0 (result is always 1)
