   Hello, one again, I went with the GUI version:

   Here’s the heart of the code that does it all:

   public void Calculation(){

   float number1, number2, number3;
   number1 = Float.parseFloat(jTextField1.getText());
   number2 = Float.parseFloat(jTextField2.getText());
   number3 = Float.parseFloat(jTextField3.getText());

   float answer = Math.min( number1, Math.min(number2, number3));

   jTextField4.setText(String.valueOf(answer));

   }

   public void Clear(){
   //clears all text boxes
   jTextField1.setText(”");
   jTextField2.setText(”");
   jTextField3.setText(”");
   jTextField4.setText(”");
   }

   and the buttons that calls these methods.
   private void jButton2ActionPerformed(java.awt.event.ActionEvent evt) {
   Clear();
   }

   private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {

   Calculation();
   }

   private void jMenuItem1ActionPerformed(java.awt.event.ActionEvent evt) {
   Calculation();
   }

   private void jMenuItem2ActionPerformed(java.awt.event.ActionEvent evt) {
   Clear();
   }

   I made the two methods, and within the calculate and clear buttons/menu items (under my options pane), I called these methods. I decided to do this because it makes no sense to write the code multiple times in each button. I wrote the code once and called it four times.

   here’s my screen shot:

   OK, the following 3 text files contain the codes for you to look at:

   The following zip file is the complete package, download, unzip and tweak how ever you want it!

   it’s simple, create gui application.
   add 2 buttons,
   4 textboxes,
   within the program code make the method:

   public void Calculation(){

   float number1, number2, number3;
   number1 = Float.parseFloat(jTextField1.getText());
   number2 = Float.parseFloat(jTextField2.getText());
   number3 = Float.parseFloat(jTextField3.getText());

   float answer = Math.min( number1, Math.min(number2, number3));

   jTextField4.setText(String.valueOf(answer));

   }

   ——–+++++and ++++——

   public void Clear(){
   //clears all text boxes
   jTextField1.setText(”");
   jTextField2.setText(”");
   jTextField3.setText(”");
   jTextField4.setText(”");
   }

   Here’s calculate button code:
   private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {

   Calculation();
   }

   and here’s the clear button code:
   private void jButton2ActionPerformed(java.awt.event.ActionEvent evt) {
   Clear();
   }

   You’re done, you have a running application, you should add labels to explain what does what though.
