Write a Java Program with Algorithm to copy all elements of one array into another array.

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
