}When I compile it, it will show up like I want it to. But when I click the menu and go down to the calculator I want to pop up, only the window pops up. There's nothing in it. How would I take the input from the user and tell the user if they are overweight or not?
  if ( weight == 0){
            BMI2TextField.setText("Noob");
           }else{
              if( BMI < 18.5){
                  BMI2TextField.setText("UnderWeight");
              }else{
               if( BMI >= 18.5 && BMI <= 24.9){
                  BMI2TextField.setText("Normal");
              }else{
              if( BMI >= 25 && BMI <= 29.9){
                  BMI2TextField.setText("Overweight");
              }else{
              if( BMI > 30){
                  BMI2TextField.setText("Obese");
              }else{
         BMI2TextField.setText("Your BMI is :" + BMI);
}I thought it was that, but when I open the calculator nothing shows up in the window. What do I need to do to take input from the user and output the needed info from the above text?

Answer 1

What do I need to put BMI as? I don't know if having it as a MenuItem is working.
When I compile it, it will show up like I want it to.???
If you didn't understand, I meant that it compiles and opens a GUI window. Just a blank window with a Menu Bar. With two calculators that drop down. When I click the BodyMassIndex one a new GUI window opens up. But nothing is in it. How do I get the user to input the information and output the result of it? This is really confusing me.
