    There are two Timer classes. One in the javax.swing package and one in the java.util package. The compier needs to be told which one to use.
    One way is to explicitly code the package name with the class name:

    javax.swing.Timer myTimer = new javax.swing.Timer(...);

    then the compiler will know which one to use.

    The compiler can not find the definition for the TimerActionListener class. Where is it defined?

    not sure if this is correct
    The compiler will tell you. If there are no errors, then it could be correct.

    Sorry, I don't know about your IDE's error messages.

    The formatting of the code is bad enough that it is hard to see where methods begin and end.

    The missing class's definition must be out of scope for where it is referenced. Try moving its definition so it is in scope where it is referenced.
