How many frames will display with these codes?
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
What happens in this code and why?
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Write a GUI random number generator that works with startup screen, a screen showing user input, After user input press enter
The input is taken from the TextField and number extracted (use Integer.parseInt(str)). The TextField should then be cleared
A message is shown in a label below the TextField. message reads “Your random number between 1 and n is: x†with n from user input and x is a random number in range [1, n]
Solution
import javax.swing.*;
public class Test {
public static void main(String[] args) {
JFrame f1 = new JFrame(\"My Frame\");
JFrame f2 = f1;
JFrame f3 = f2;
f1.setVisible(true);
f2.setVisible(true);
f3.setVisible(true);
}
}
OUTPUT:
ONLY ONE Frame IS DISPLAYED
import javax.swing.*;
public class Test extends JFrame {
public static void main(String[] args) {
JFrame f1 = new Test();
JFrame f2 = new Test();
JFrame f3 = new Test();
f1.setVisible(true);
f2.setVisible(true);
f3.setVisible(true);
}
}
OUTPUT:
3 FrameS ARE DISPLAYED
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import javax.swing.JFrame;
public class Test extends JFrame {

}
});
}
public static void main(String[] args) {
JFrame frame = new Test();
frame.setSize(300, 300);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setVisible(true);
}
}
OUTPUT:
Nothing is displayed
