Quiz game using java

In this program, we will learn how to create a quiz game using java swing GUI. In this program, we will use the Action listener method and Swing class. first, we create a frame according to the quiz. we use container pane for holding the components.

Create Quiz Game in Java Swing GUI

Here we will create a frame. There will be four options for each question. We will be able to choose any option and then we will be able to submit our answer. We will get the output either: Right answer or Wrong Answer

Java program to build a Java GUI quiz game – Swing

import javax.swing.*;
import java.awt.event.*;
import java.awt.*;
class KbcTest implements ActionListener
{
JFrame fr;
JRadioButton rb1,rb2,rb3,rb4;
JButton b1,b2;
JLabel lb1,lb2;
ButtonGroup bg;
String ques[]={"who developed java?","capitol of italy"};
String op1[]={"Tim","peris"};
String op2[]={"steve","Delhi"};
String op3[]={"mark","Rome"};
String op4[]={"james","bern"};
String ans[]={"james","Rome"};
int cn;
KbcTest()
{
fr=new JFrame();
fr.setLayout(null);
fr.setSize(600,600);
Container c=fr.getContentPane();
c.setBackground(Color.cyan);

lb1=new JLabel(ques[0]);
lb1.setBounds(50,50,300,30);
fr.add(lb1);
lb1.setFont(new Font("chiller",Font.BOLD,30));

rb1=new JRadioButton(op1[0]);
rb1.setBounds(100,120,100,30);
fr.add(rb1);

rb2=new JRadioButton(op2[0]);
rb2.setBounds(350,120,100,30);
fr.add(rb2);
rb3=new JRadioButton(op3[0]);
rb3.setBounds(100,200,100,30);
fr.add(rb3);
rb4=new JRadioButton(op4[0]);
rb4.setBounds(350,200,100,30);
fr.add(rb4);
bg =new ButtonGroup();
bg.add(rb1);
bg.add(rb2);
bg.add(rb3);
bg.add(rb4);
rb1.addActionListener(this);
rb2.addActionListener(this);
rb3.addActionListener(this);
rb4.addActionListener(this);

b1=new JButton("Sumbit");
b1.setBounds(100,400,100,30);
fr.add(b1);

b2=new JButton("Next");
b2.setBounds(250,400,100,30);
fr.add(b2);
b1.addActionListener(this);
b2.addActionListener(this);
fr.setVisible(true);
}
public static void main(String s[])
{
new KbcTest();

}
public void actionPerformed(ActionEvent e)
{
if(e.getSource()==b1)
{

String en="";
if(rb1.isSelected())
en=rb1.getText();
if(rb2.isSelected())
en=rb2.getText();
if(rb3.isSelected())
en=rb3.getText();
if(rb4.isSelected())
en=rb4.getText();
if(en.equals(ans[cn]))
JOptionPane.showMessageDialog(null,"Right Answer");
else
JOptionPane.showMessageDialog(null,"Wrong Answer");
}
if (e.getSource()==b2)
{
cn++;
lb1.setText(ques[cn]);
rb1.setText(op1[cn]);
rb2.setText(op2[cn]);
rb3.setText(op3[cn]);
rb4.setText(op4[cn]);
}
}
}

 

Now, we understand the code in this code we create a button group for holds the radio buttons and perform the action listener method to all button groups.
I hope all of you are understand the problem if not please mention in the comment section we will be reply as soon as possible

   public static void main(String[] args) { Scanner input = new Scanner(System.in); String[] answerkey = {“e”,”d”,”c”,”b”,”a”}; int n = 0; int correct = 0; int incorrect = 0; String answer = “”; for (int i = 0; i 4){ System.out.println(“Correct.”); } else { System.out.println(“Wrong.”); } System.out.println(“Your marks ” + correct + ” correct answers.”);
