Question

Java Program to copy all elements of one array into another array

Answer 1

Explanation:

STEP 1: START

STEP 2: INITIALIZE arr1[] ={1, 2, 3, 4, 5}

STEP 3: CREATE arr2[] of size arr1[].

STEP 4: COPY elements of arr1[] to arr2[]

STEP 5: REPEAT STEP 6 UNTIL (i<arr1.length)

STEP 6: arr2[i] =arr1[i]

STEP 7: DISPLAY elements of arr1[].

STEP 8: REPEAT STEP 9 UNTIL (i<arr1.length)

STEP 9: PRINT arr1[i]

STEP 10: DISPLAY elements of arr2[].

STEP 11: REPEAT STEP 12 UNTIL (i<arr2.length)

STEP 12: PRINT arr2[i].

STEP 13: END

Answer 2

We can clone or copy an Object using the clone( ) method of Object class so, we can ultimately clone an Array too.

Demonstration

Code:

import java.util.Arrays;  

public class CopyArray {

   public static void main(String[ ] args) {

       // Test array to copied

       int[ ] array = {1, 5, 2, 4, 7, 6, 9, 3, 0};

       System.out.println("Original Array - " + Arrays.toString(array));

       // New copied array

       int[ ] newArray = array.clone( );

       System.out.println("New Array - " + Arrays.toString(newArray));

   }

}

Output:

Original Array - [1, 5, 2, 4, 7, 6, 9, 3, 0]

New Array - [1, 5, 2, 4, 7, 6, 9, 3, 0]
