How to find a continuous subarray with a sum equal to a given number in Java?

Find a continuous subarray whose sum equals the given number-

  • Traverse the array.

  • On each element, add n elements one by one, and print the subarray when the sum equals the required value.

Example

import java.util.Arrays;
import java.util.Scanner;
public class sub_arrays {
   public static void main(String args[]){
      //从用户读取数组
      Scanner sc = new Scanner(System.in);
      System.out.println("Enter the size of the array that is to be created: ");
      int size = sc.nextInt();
      int[] myArray = new int[size];
      System.out.println("Enter the elements of the array: ");
      for (int i = 0; i < size; i++{
         myArray[i] = sc.nextInt();
      }
      //Reading the number
      System.out.println("Enter the required sum: ");
      int reqSum = sc.nextInt();
      System.out.println("The array created is: "+Arrays.toString(myArray));
      System.out.println("sub arrays whose sum is: "+reqSum);
      for (int i = 0; i < myArray.length; i++{
         int sum = 0;
         for (int j = i; j < myArray.length; j++{
            sum = sum + myArray[j];
            if(sum == reqSum){
               System.out.println(Arrays.toString(Arrays.copyOfRange(myArray, i, j));+1);
            }
         }
      }
   }
}

Output Result

Enter the size of the array that is to be created:
10
Enter the elements of the array:
5
4
1
2
3
4
1
4
5
5
Enter the required sum:
10
The array created is: [5, 4, 1, 2, 3, 4, 1, 4, 5, 5]
sub arrays whose sum is: 10
[5, 4, 1]
[4, 1, 2, 3]
[1, 2, 3, 4]
[2, 3, 4, 1]
[1, 4, 5]
[5, 5]
