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

In this program, we need to copy all the elements of one array into another. This can be accomplished by looping through the first array and store the elements of the first array into the second array at the corresponding position.

ARRAY 1 =1   2  3  4  5

ARRAY 2 = 1   2  3  4  5

### Algorithm

• 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

### Program:

1. public class CopyArray {
2.     public static void main(String[] args) {
3.              //Initialize array
4.         int [] arr1 = new int [] {1, 2, 3, 4, 5};
5.          //Create another array arr2 with size of arr1
6.         int arr2[] = new int[arr1.length];
7.         //Copying all elements of one array into another
8.         for (int i = 0; i < arr1.length; i++) {
9.             arr2[i] = arr1[i];
10.         }
11.          //Displaying elements of array arr1
12.         System.out.println(“Elements of original array: “);
13.         for (int i = 0; i < arr1.length; i++) {
14.            System.out.print(arr1[i] + ” “);
15.         }
16.
17.         System.out.println();
18.
19.         //Displaying elements of array arr2
20.         System.out.println(“Elements of new array: “);
21.         for (int i = 0; i < arr2.length; i++) {
22.            System.out.print(arr2[i] + ” “);
23.         }
24.     }
25. }

Output:

``` Elements of original array
1 2 3 4 5
Elements of new array:
1 2 3 4 5```
