Sample Solution:
Java Code:
import java.util.*;
import java.io.*;
public class Exercise31 {
public static void main(String[] args)
{
int[] array_nums = {10, 77, 10, 54, -11, 10};
System.out.println("Original Array: "+Arrays.toString(array_nums));
int search_num = 10;
int fixed_sum = 30;
System.out.println("Result: "+result(array_nums, search_num, fixed_sum));
}
public static boolean result(int[] numbers, int search_num, int fixed_sum) {
int temp_sum = 0;
for (int number : numbers) {
if (number == search_num) {
temp_sum += search_num;
}
if (temp_sum > fixed_sum) {
break;
}
}
return temp_sum == fixed_sum;
}
}
Sample Output:
Original Array: [10, 77, 10, 54, -11, 10] Result: true
