Thread: having a little trouble

I am a student and have an assignment due, I have been trying to figure out this issue for the past 3 days and have yet to get this to work properly without errors. Is there anyone who can help me fix this?

        totalBMI.setText("Your more accurate BMI is: " + bmiTot); //This is where 1 error is, the bmiTot
        //totalBMI.setText("Your more accurate BMI is: " + );
        if (gender == T | gender == t){ //the other 2 errors are both "t" and "T". I've tried string, char and boolean
            if (height >= 65 && wrist >= 7.5){

        frame.setSize(385,255);
        frame.setVisible(true);
}
}

netbeans is the IDE we have to use for the class

This is editted and fixed one problem but created another

 public void actionPerformed(ActionEvent event) {
        String gender = trueFalse.getText();
        double pounds = Double.parseDouble(heavy.getText());
        double height = Double.parseDouble(inches.getText());
        double wrist = Double.parseDouble(circum.getText());
        double num1 = height*height;
        double bmi = (pounds/num1)*703;
 
        //totalBMI.setText("Your more accurate BMI is: " + bmiTot);
        //totalBMI.setText("Your more accurate BMI is: " + );
        double bmiTot = if (gender == () | gender == ()){
            if (height >= 65 && wrist >= 7.5){
                bmiTot = bmi*.9;
            }else   {
                bmiTot = bmi;
            }                
            }else   {
                if (height >= 65 && wrist >= 6.5 || height > 62 && height < 65 && wrist >= 6.25 || height <= 62 && wrist > 5.75){
                    bmiTot = bmi*.9;
            }else   {
                    bmiTot = bmi;
                }
        };
        totalBMI.setText("Your more accurate BMI is: " + bmiTot);

double bmiTot = if (gender == () | gender == ()){

now gives 3 errors stating illegal start of statement

the "t" and "T" are options for a string entry

double bmiTot = if (gender == () | gender == ()){

If statements do not return a value. So what value are your expecting to be assigned to the bmiTot variable?

bmiTot is supposed to return the result of of the if statement's calculation

if i enter it like this:

double bmiTot = //then my error is here (illegal start of expression)
if (gender.equals(T) | gender.equals(t)){
if (height >= 65 && wrist >= 7.5){
bmiTot = bmi*.9;
}else {
bmiTot = bmi;
}
}else {
if (height >= 65 && wrist >= 6.5 || height > 62 && height < 65 && wrist >= 6.25 || height <= 62 && wrist > 5.75){
bmiTot = bmi*.9;
}else {
bmiTot = bmi;
}
};
totalBMI.setText("Your more accurate BMI is: " + bmiTot);

nevermind. I figured it out, my space provided wasn't big enough.

thank you guys so much for helping me with this!!!

here is the completed code if anyone wants it for anything
