Question

Java - Up/Down - Please use WidgetViewer, similar solutions do not.

Write a WidgetViewer GUI that has the following widgets:

a button labeled "go up/down"

a label initialized to 0 (we'll call this the left label)

a label initialized to 0 (we'll call this the right label)

a button labeled "go down/up"

When the "go up/down" button is pushed, a random number between 1 and 10 (inclusive) is generated and added to the left label, and another random number between 1 and 10 (inclusive) is generated and subtracted from the right label.

When the "go down/up" button is pushed, a random number between 1 and 10 (inclusive) is generated and subtracted from the left label, and another random number between 1 and 10 (inclusive) is generated and added to the right label.

Grading Elements

The program uses WidgetViewer to provide a GUI environment

The program displays two JButtons and two JLabels, as specified

The program uses one or more event handlers to detect user input and take appropriate action

The program generates two random numbers in the appropriate ranges when a button is clicked

The program manipulates the JLabels as specified based on the buttons clicked by the user

Explanation / Answer

As per your requirement i have written code which fulfill all your requirements please follow it step by step.

import javax.swing.*; //It is used for Swing class

import java.util.Random; //It is used for random number creation

import java.awt.event.*; //It is used for Event handling

import java.awt.BorderLayout; //It is used for layout manager

public class randUPDOWN extends JFrame

{

//Here we will creates JButton class object

JButton UpDownElement;

//Next here we will creates JLabel class object

JLabel leftLElement, leftCElement, rightCElement, rightLElement;

//Here we will creates JFrame class object

JFrame ffElement;

//Next here we will creates JPanel object

JPanel p1Element, p2Element;

randUPDOWN()

{

//Here we will reate an instance of JFrame class

ffElement = new JFrame("Up Down Operation");

//Next we will sets the layout manager to border layout

ffElement.setLayout(new BorderLayout());

//after we will initializes the JPanel class object

p1Element = new JPanel();

p2Element = new JPanel();

//Next to that initializes JLabel objects

leftLElement = new JLabel("0");

rightLElement = new JLabel("0");

leftCElement = new JLabel("Left");

rightCElement = new JLabel("Right");

//after that initializes JButton class object

UpDownElement = new JButton("go down/up");

//after that add labels to the panel 1

p1Element.add(leftCElement);

p1Element.add(leftLElement);

p1Element.add(rightCElement);

p1Element.add(rightLElement);

//After that adds button to the panel 2

p2Element.add(UpDownElement);

//Later do positions the panels

ffElement.add(p1Element, BorderLayout.NORTH);

ffElement.add(p2Element, BorderLayout.SOUTH);

ffElement.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

ffElement.setSize(200,200);

ffElement.setVisible(true);

//Next perform action listener for UpDownElement button

UpDownElement.addActionListener(new ActionListener()

{

public void actionPerformed(ActionEvent ar0)

{

//Here we will creates the Random class object

Random randomObject = new Random();

int LowElement = 1;

int HighElement = 10;

//Here we will generates the random number

int ResultantValue = randomObject.nextInt(HighElement-LowElement) + LowElement;

int leftValue = Integer.parseInt(leftLElement.getText()) - ResultantValue;

int rightValue = Integer.parseInt(rightLElement.getText()) + ResultantValue;

leftLElement.setText(String.valueOf(leftValue));

rightLElement.setText(String.valueOf(rightValue));

}

});

}

public static void main(String[] args)

{

randUPDOWN randomObject = new randUPDOWN();

}   

}
