This is the code that given in our programming instructor and their are errors in this code. the error says "cannot find symbol variable enter":(
this project will submitted this coming wednesday thanks for the help..

Edited 5 Years Ago by twinkle2011: n/a

cannot find symbol variable enter

The error is because you dint declared the variable before using it in your code.

The error is because you dint declared the variable before using it in your code.

Can you teach how? im so confuse about the codes, and im not the one who make this codes

propably the point of this exercise is for you to figure out the obvious: why this code isn't working and to correct it.
it is very, very basic to declare a variable. if you are taking a programming class, chances are this is about the first thing you've learned about, so just overlook your notes of the first classes, or just google what harinath_2007 suggested:
'java declare a variable' that should get you all the information you need.
