Hi All,

I am new in using Java and javax.swing.
I am using the University Version JBuilder 3.0

I am working on my final project and I keep getting an "Exception in thread
"main" java.lang.NullPointerException
at Calculator.Calculator.<init><Caluclator.java: 147> and
at Calculator.Calculator.main<Calculator.java:74>

I am trying to convert a Java app to a Javax.Swing app

can anyone tell what this message means?
