Java 11 cannot find symbol

[Wyvern]

I have a small piece of code which on compilation reults in unexpected exception : "UsingExceptions.java:11: cannot find symbol". This code was working perfectly OK before but suddenly started showing me problem. Can anyone help me why is this error appearing?

You might be using some variables in your code that is not defined anywhere. In other words, a variable that is undefined results in this kind of error messages. Just make sure all your variables are defined and at proper locations.

[!const]

This error occurs when compiler has found a variable name that it doesn't recognize or a method call that is missing parentheses. Is there any variable in your code that is misspelled or left undeclared. Also make sure that all the method has opening and closing parentheses.
