Example 1

//import statement

import java.lang.reflect.Array; 
public class ReflectArraysetDoubleExample1 { 
    public static void main(String[] args) 
    { 
        double arr[] = new double[3];  
        Array.setDouble(arr , 0 , 2.4);
          Array.setDouble(arr , 1 , 7.4);
            Array.setDouble(arr , 2 , 9.4);
        
        for (int i = 0; i < arr.length; i++) { 
  
            double vl = Array.getDouble(arr, i); 
            System.out.print(vl + "  , ");
