Thread: Var Might have been initialize

Hello, Soo my java coding has this 2 ways of paymentterm that is cash and credit.
the problem is the category of the File that is being read would be on the Payment Term.
and the payment term would have cash and credit. So what i'm trying to say is that I want the cash and credit to be written in a different output because one of them has a discount.

so I use IF Statement.. which is If ( PaymentTerm == CREDIT )

but apparently the error said Variable Credit might not have been initialize
What should I actually should put?
ps. Im using BlueJ

The error message is pretty clear. You should initialize that variable. And another think I noticed:

if( PaymentTerm == CREDIT  )

You should use the String's equals method instead of the == operator when you want to compare the contents of Strings.

Hope this helps.

Thanks it helped even though i wasn't taught on how to use it~ decided to lurk around on what u meant.
