help learing JAVA

I am attempting to learn Java for a hobby (haven't written code in 15 years) I am using netbeans and found a good document on oracle.com to help get started however either I am missing the obvious or there is a problem with this site. I'm hoping someone can tell me how to get this to work.

The article is http://www.oracle.com/technetwork/java/netbeans-part1-142734.html#figure7. If you scroll down a bit it tells you to name the variable jlabel6, jlable7 and jlabel8 to ******

When I try that it says it is not a valid variable name. I would think that it needs to be variable name, not asterisks since it will be the results of a calculated field.

Any help for a beginner is very much appreciated.

They recommedn to change not the variable name but the contenst of the text of the label

i guess that is the label of the field rather than the name

Variable name in java can only start with letter and contain charcacters , distis and underscore
They are talking about the contesnt of the text of the lable this contents is data - struig and it can be blank, or asteriksk, or amny
printesd symnbols,
the name of the variables does not need to be changed at this point

I think they misplace this remark, yuou cannot change jlablel to ****

To rename a component, right-click it in either the Design Editor or the Inspector and choose Change Variable Name. Change names for the following components:

This part

Variable Text
jLabel6 **********
jLabel7 **********

Variable Text

jLabel2 Rate/ Hour ($):
jLabel3 Regular Pay:
jLabel4 Overtime Pay:

It looks like they left out some information. I needed to name those variables according to the last lines of code

regularPayField.setText(" " + nfRegular.format(regularPay));
overtimePayField.setText(" " + nfOverTime.format(overTimePay));
totalField.setText(" " + nfTotal.format(total));
