basic Array programs

 Array basic

1. Sum of array in java.

//Sum of array in java.

  import java.util.Scanner;

  public class SumOfN {

      public static void main(String[] args) {

          Scanner s = new Scanner(System.in);

          int N = s.nextInt();

          // Define an array of integers of size N. 
          int[] numArray = new int[N];		


          int sum = 0;
          for(int i=0; i < N; i++){
              numArray[i] = s.nextInt(); // Get the input
          }

          // Write the logic to add these numbers here:

          for(int i=0;i < N; i++){
              sum = sum + numArray[i];
          }


          // Print the sum
          System.out.print(sum);
          s.close();
      }

  }

2. Sum of 2 Arrays

  //SUM OF TWO ARRAYS

  import java.util.Scanner;

  public class AddTwoArrays {

      public static void main(String[] args) {

          Scanner s = new Scanner(System.in);

          // Reading integer from input
          int N = s.nextInt();

          int[] numArrayA = new int[N];
          int[] numArrayB = new int[N];
          int[] sumArray = new int[N];

          // Read numArray1
          for(int i=0; i < N; i++) {
              numArrayA[i] = s.nextInt();
          }
          // Read numArray2
          for(int i=0; i < N; i++) {
              numArrayB[i] = s.nextInt();
          }
          for(int i=0; i < N; i++) {
              sumArray[i] = numArrayA[i] + numArrayB[i];
          }       

         // Print the sumArray
          for(int i=0; i < N; i++) {
              System.out.print(sumArray[i] + " ");
          }

          System.out.println();
          s.close();

      }

  }
