Copy the content of an array (source) to another array (destination) in Java

Description

The following code shows how to copy the content of an array (source) to another array (destination).

System.arraycopy() copies the content of an array (source) to another array (destination), beginning at the specified position, to the specified position of the destination array.

Example

  
public class Main {
/*from www .j  a va 2s . c  o m*/
  public static void main(String[] a) {
    int[] array1 = { 1, 2, 3, 4 };
    int[] array2 = new int[array1.length];
    System.arraycopy(array1, 0, array2, 0, array1.length);

    for(int i: array2){
      
      System.out.println(i);
    }
  }
}

The code above generates the following result.
