How to resize an array and preserve the data in Java

Answer 1

import java.util.Arrays;

class Program {
    public static void main(String[] args) {
        int[] arr = {1, 3, 5, 6, 9, 10, 12, 13};

        int[] newArray = Arrays.copyOf(arr, arr.length + 5); 

	    System.out.println(Arrays.toString(newArray));  
    }
}



      
/*
run:
      
[1, 3, 5, 6, 9, 10, 12, 13, 0, 0, 0, 0, 0]
     
*/
