hi ......i'm very new to java...i'm learning core java for 2 months....i'm getting errors while devoloping a frame based checkbox application ....please look into that and help me to devolope that ...sorry for my bad english ..


here is the program

//CbDemo.java



//it is showing that line no. 34 is an error ....

Cb.Sathya is not abstract method and does not override abstract method ItemStateChanged(ItemEvent) in ItemListener

Look at the method in ItemListener. Look at the method you've implemented. Compare them, carefully. And remember that Java is case sensitive.
