✐ Examples
1 Copying an Array
In this example,
- We create an array named
array1
with elements. - We then use the
arraycopy()
method to copyarray1
intoarray2
. arraycopy()
method copies a range of elements from one array to another array.
Java Program
import java.util.Arrays;
// Copying an Array
public class Main {
public static void main(String[] args) {
int[] array1 = {1, 2, 3, 4, 5};
int[] array2 = new int[array1.length];
System.arraycopy(array1, 0, array2, 0, array1.length);
System.out.println("Array 1: " + Arrays.toString(array1));
System.out.println("Array 2 (copy of Array 1): " + Arrays.toString(array2));
}
}
Output
Array 1: [1, 2, 3, 4, 5] Array 2 (copy of Array 1): [1, 2, 3, 4, 5]
