True or false game problem

Question

hey all, its me, the java noob!
i've been trying to make a true or false game in which the user has to do the obvious with two of the buttons and press go to start the whole thing.
however, my program has seriusly gone fooba, it says the wrong wrong answere statements, it jumps to another question whe i give an answere and soemtimes says i'm wrong when i'm not. what am i doing wrong?
i'm seriusly confused about what i did wrong. here's the code:
import java.util.Random;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.*;
import java.awt.FlowLayout;
class TF extends JFrame implements ActionListener{
     public static void main(String args[]){
          new TF();
     int otherNum = 0;
     int TFnum = 1;
     JButton t = new JButton("true");
     JButton f = new JButton("false");
     JLabel tf = new JLabel();
     JButton BUtton = new JButton("go!");
     public TF(){
     setDefaultCloseOperation(EXIT_ON_CLOSE);
     setLayout(new FlowLayout()) ;
     add(tf);
     tf.setVisible(false);
     add(BUtton);
     BUtton.addActionListener(this);
     add(t);
     t.addActionListener(this);
     t.setEnabled(false);
     add(f);
     f.addActionListener(this);
     f.setEnabled(false);
    pack();
    setVisible(true);     
     public void actionPerformed(ActionEvent e){
     if(e.getSource() == BUtton){
          t.setEnabled(true);
          f.setEnabled(true);
          tf.setVisible(true);
          BUtton.setEnabled(false);
    int tfr = new Random().nextInt(10) + 1;
     switch (tfr) {
     case 1:
     TFnum = 2;
     otherNum = 1;
     tf.setText(" chess was first invented in India");
     break;
     case 2:
     otherNum = 2;
     TFnum = 0;
     tf.setText("Calvin and hobbes were both names of people in the past one was named Jhon Hobbes and the other named Thomas Calvin t/f");
     break;
     case 3:
     otherNum = 3;
     TFnum = 2;
     tf.setText("a microphone needs a windscreen which is usually made of polyster t/f");
     break;
     case 4:
     otherNum = 4;
     TFnum = 0;
     tf.setText("octopus's ink squirt is a good defense, however, the smell the ink lets off creats a direct path towards the octopus t/f");
     break;
     case 5:

     TFnum = 2;
     tf.setText("Monty Python and the holy grail planned to have a sequal in 1990, but that idea was posponed t/f");

     break;
     case 7:

     TFnum = 2;
     tf.setText("the famous series Doctor who first started in 23 November 1963 t/f");
     break;
     case 8:

     tf.setText("Albert Einstien invented the first laser, albeit only a maschine which caught and concentrated sunlight.");
     break;
     if(e.getSource() == t) {
          t.setEnabled(false);
             f.setEnabled(false);
        if(TFnum == 0) {
             t.setEnabled(false);
             f.setEnabled(false);
              if(otherNum == 2){
               tf.setText("you lose, it was Jhon Calvin and Thomas Hobbes (I switch names around)");
              if(otherNum == 4){
               tf.setText("you lose, the ink blocks all sense of smell");
               if(otherNum == 6){
               tf.setText("you lose, the H's are at 104.45 degrees, so nearly a triangle shape");
              if(otherNum == 8){
               tf.setText("you lose, actually, its 5000 years old and was discovered in eastern Iran as part of a backgammon set");
              if(otherNum == 10){
               tf.setText("you lose, he set the principal but never invented it.");
         } else {
         tf.setText("you win!!!");
    if(e.getSource() == f) {
        t.setEnabled(false);
             f.setEnabled(false);
    if(TFnum == 2){
      tf.setText("you lose");     
      } else {
      tf.setText("you win");
  }i get absolutely no error messages but everything does exactely what its NOT meant to do
if you help me : THANK YOU VERY MUCH !!!!! :)

Answer 1

well, it vary's, but the overall picture is that when i get
A) the true button when its false, it gives a Random answere instead of the one i need e.g. when i say that Einstien did invent the first laser (which is bollucks) it says "you lose, the anlgles at which the H's stand to the o is 104.45 degrees" which is not whatits meant to do because that was the answer for a chemical question.
B) when its false and i click false, it goes perfect!
C) when i click true and it is true,it goes completely and uterly mad and tells me some sort of "you lose" statement.
hope that helps
