PS: Please upload the output and say the logic behind it. Thank you!

What is computer?

Question 1

What will be the output of the following Java Program?

// file name: Main.java
  public class Main {
      public static void main(String args[]) {
           int arr[] = {10, 20, 30, 40, 50};
           for(int i=0; i < arr.length; i++)
          {
                          System.out.print(" " + arr[i]);
             }
          }
}

Question 2

What will be the output of the following Java Program?

public class Main {
         public static void main(String args[]) {
             int arr[][] = new int[4][];
             arr[0] = new int[1];
             arr[1] = new int[2];
             arr[2] = new int[3];
             arr[3] = new int[4];

                  int i, j, k = 0;
                  for (i = 0; i < 4; i++) {
                         for (j = 0; j < i + 1; j++) {
                          arr[i][j] = k;
                          k++;
                 }
              }
                         for (i = 0; i < 4; i++) {
                               for (j = 0; j < i + 1; j++) {
                                   System.out.print(" " + arr[i][j]);
                                    k++;
                              }
                                 System.out.println();
                 }
        }
}

Question 3

What will be the output of the following Java Program?

class Test {
      public static void main(String args[]) {
       int arr[] = new int[2];
       System.out.println(arr[0]);
       System.out.println(arr[1]);
  }
}

Question 4 

What will be the output of following Java program?

class Test
{
        public static void main (String[] args)
         {
              int arr1[] = {1, 2, 3};
              int arr2[] = {1, 2, 3};
              if (arr1.equals(arr2))
                    System.out.println("Same");
               else
                    System.out.println("Not same");
        }
}

Question 5

What will be the output of following Java program?

class Test
{
public static void main (String[] args)
{
          int arr1[] = {1, 2, 3};
          int arr2[] = {1, 2, 3};
          if (arr1 == arr2)
                System.out.println("Same");
         else
                System.out.println("Not same");
      }
}

Question 7

What will be the output of following Java program?

import java.util.Arrays;
class Test
{
           public static void main (String[] args)
            {
                int arr1[] = {1, 2, 3};
                int arr2[] = {1, 2, 3};
                if (Arrays.equals(arr1, arr2))
                     System.out.println("Same");
                else
                     System.out.println("Not same");
        }
}
