# Java: Compute the sum of the prime numbers till 100

## Java Basic: Exercise-66 with Solution

Write a Java program to Compute the sum of the prime numbers till 100.

Pictorial Presentation: Sample Solution:

Java Code:

``````import java.util.*;

public class Exercise66 {
public static void main(String[] args) {
// Initialize variables for sum, counter, and the number 'n'
int sum = 1;
int ctr = 0;
int n = 0;

// Iterate while the counter is less than 100
while (ctr < 100) {
n++;

// Check if the number is odd
if (n % 2 != 0) {
// If the number is prime, add it to the sum
if (is_Prime(n)) {
sum += n;
}
}

// Increment the counter
ctr++;
}

// Print the sum of prime numbers up to 100
System.out.println("\nSum of the prime numbers till 100: " + sum);
}

// Check if a number is prime
public static boolean is_Prime(int n) {
for (int i = 3; i * i <= n; i += 2) {
if (n % i == 0) {
return false;
}
}
return true;
}
}
```
```

Sample Output:

```Sum of the prime numbers till 100: 1060
```
