"Can not find " means that , the compiler who can't find an appropriate variable, method ,class class, etc...if If you got that error massage , first of all, you want to find the code line where you get the error massage..And
And then you will able to find which variable , method or class have not definebeen defined before using it.After After confirmation initialize, initialize that variable ,method method or class, so it can be used for a later require..require.Consider Consider the following example.
I'll create a demo class and print a name...
class demo{ { public static void main(String a[]) { System.out.print(name); } } Now look at the result..
That error says, "variable name can not find"..Defining Defining and initializing value for 'name' variable cancan be abolished that error..Actually Actually like this,
class demo{ { public static void main(String a[]) { String name String= name="smith";"smith"; System.out.print(name); } } Now look at the new output...
Ok Successfully, we successfully solved that error..At At the same time , if you could get "can not find method " or "can not find class" something , Atat first,define define a class or method and after use that..
