Still very confused.
I need to get from the txtGPA (name of my textbox), and store it as a float in my array.

I'm new to Java so any help is appreciated.

float[] arr = new float[3];
// use the method to get the value of textbox and parse to float
float[0] = Float.parseFloat(textGPA.getValue());
 
 

something like that...

float floatValue = Float.parseFloat(txtGPA.getText());



parseFloat(String str) is the static method of class Float

Thank you so much! That all worked great.
