Arrays Copy Range 

The following example shows how to use Arrays.copyOfRange API. It copies the specified range of the specified array into a new array. The initial index of the range (from) must lie between zero and original.length, inclusive and end index (to) is the final index of the range to be copied, exclusive.

package com.bethecoder.tutorials.utils.arrays;

import java.util.Arrays;

public class ArraysCopyRange {

  public static void main (String [] args) {
    
    char [] chrArray = 'b''e''t''c''o''d''e''r' };
    System.out.println("Before copy : " + Arrays.toString(chrArray));
    
    //Copy array from index 3 to 8 (exclusive)
    char [] chrArray2 = Arrays.copyOfRange(chrArray, 38);
    chrArray2[4'd';
    
    System.out.println("Copied array : " + Arrays.toString(chrArray2));
    System.out.println("Original array : " + Arrays.toString(chrArray));
    
  }
}
   

It gives the following output,
Before copy : [b, e, t, c, o, d, e, r]
Copied array : [c, o, d, e, d]
Original array : [b, e, t, c, o, d, e, r]


                    Print
