Here's how:
// Create an array with room for 100 integers
int[] nums = new int[100];
// Fill it with numbers using a for-loop
for (int i = 0; i < nums.length; i++)
nums[i] = i + 1; // +1 since we want 1-100 and not 0-99
// Compute sum
int sum = 0;
for (int n : nums)
sum += n;
// Print the result (5050)
System.out.println(sum);
