Thread: question about my applet

need to write write a Java applet that will let the user guess the gas price and compare it with the price predicted by my program. Guess gas price (100 - 150): that never changes. so far i have this but stuck with method, generate a random number from 100 to 150, inclusive. Set it to predictPrice. so far i have this

import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
 
import javax.swing.JApplet;
import javax.swing.JLabel;
import javax.swing.JTextField;
 
public class Assign7 extends JApplet implements ActionListener
{
int predictPrice;
int guessPrice;
 
JLabel questionLabel;
JTextField answerField;
 
public void init ()
{
 
Container container = getContentPane();
container.setLayout( new FlowLayout() );
 
questionLabel = new JLabel();
container.add ( questionLabel);
answerField = new JTextField ( 3 );
answerField.addActionListener ( this );
container.add (answerField );
 
predictPrice = generateQuestion();
}
 
public void actionPerformed ( ActionEvent actionEvent )
{
 
guessPrice = Integer.parseInt(answerField.getText());
 
displayMessage();
}
public int generateQuestion()
{
int num1, num2;
 
num1 = 1 + ( int ) (Math.random() * 100 );
num2 = 1 + ( int ) (Math.random() * 150 );
 
questionLabel.setText( "Guess oil price (100 - 150)" );
 
return num1 * num2;
}
 
public void displayMessage()
{
if ( guessPrice == predictPrice)
{
showStatus ( "You are right." );
predictPrice = generateQuestion();
}
else
{
  if (guessPrice >= predictPrice);
  {
showStatus ( "Too low." );
predictPrice = generateQuestion(); 
  }
}
}
}
{
}

stuck at generating the number from 100 -150.

ok i have this now

public int generateQuestion()
{
Random rand = new Random();
int num = rand.nextInt(51) + 101;
questionLabel.setText( "Guess oil price (100 - 150)" );
 
return num;
}
 
public void displayMessage()
{
if ( guessPrice == predictPrice)
{
showStatus ( "You are right." );
predictPrice = generateQuestion();
}
else if (guessPrice >= predictPrice);
showStatus ( "Too low." );
predictPrice = generateQuestion(); 
}
}
 
{
}

no cuz im not sure on the return if i leave num as the return does it stay the same number until user guess the right price and my showstatus says "your right"

yes that what im asking. i need the number to stay the same so if i have an instance variable, called int randomNumber. and had this returned would it stay the same?
