(a) Create a new class Test_Array that has the following 3 class methods:
(i) fillArray() takes an integer array as an argument. It allows user to fill-up values in this array by using a for loop and a series of dialog boxes.

public static void fillArray(int[] value)
{
String valueInput;
String length;
length = OUDialog.request("How much Value to store?", "1");
value = new int[Integer.parseInt(length)];
for(int i=0; i<value.length; i++)
{
valueInput=OUDialog.request("Please insert an integer value", "0");
value[i]=Integer.parseInt(valueInput);
}
}


int[] a;
Test_Array.fillArray(a);


when executing the array a is stayed null and is not affected.....

hey 7anzala I'm new to the java language but i tried to see what's the problem in this project I am not familiar with the command you are using for the dialog box(which i think is your problem) but here is my way to wright this project :

The class :

import javax.swing.JOptionPane;

public class Test_Array {

public static void fillArray(int[] value){

String valueInput;
String length;
length = JOptionPane.showInputDialog("how much value to store ?");

value = new int[Integer.parseInt(length)];
for(int i=0; i<value.length; i++)
{
valueInput = JOptionPane.showInputDialog("please insert an integer value");

value[i]=Integer.parseInt(valueInput);
}
for (int i=0;i<value.length;i++){
System.out.println("value ["+i+"] = "+value[i]);
}
}
}

The main class :

public class Main {
public static void main(String[] args) {
int[] a = null ;
Test_Array.fillArray(a);
}
}

PS: the last for loop is to display the affected values in the array.

good luck

hope i helped you .......
