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

Code Java:

---

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(); 
  }
}
}
}
{
}

Again I ask- where are you stuck? I'm really not sure what you don't understand. You have an Applet, you know what you have to do... I honestly don't know what the problem is.

stuck at generating the number from 100 -150.

ok i have this now

Code Java:

---

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(); 
}
}
 
{
}

In your other thread, you said you found an algorithm for generating a random number. Where did you get stuck trying to implement that?

Hint: Math.random() gives you a random decimal between 0 (inclusive) and 1 (exclusive). The API is your friend.

...so now is your problem solved? You win the prize for most confusing poster of the day.

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"

If I'm interpreting your question correctly, the answer is no. Every time you call the generateQuestion() function, you'll return a different random number. But then again, I might be misunderstanding what you're asking.

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?

What happened when you tried that? :D
