    Default Methods

    Could someone help me with these questions?

    How do I create String array method? Is this correct?
    public static String [] getrandom ()

    How do I pass in String array into method?
    public static boolean getaccess (String[]randomNo,String realNo)

    How do I call that method. This is what I have done and it's giving me errors.
    getaccess(randomNo[],realNo);

    Thanks very much.

    it's giving me errors.
    Please copy and paste here the full text of the error messages.

    Args when calling a method should just be the names of the arg. Leave off the array notation: []

    Exception in thread "main" java.lang.RuntimeException: Uncompilable source code - Erroneous tree type: <any>
    at prog.ass.pkg3.ProgAss3.main

    I have one method to create 50 random Strings, second method for user input and third to compare them. I have done it in one method but I'm trying to do it in 3 methods.

    Did you understand the source change I suggested? Did that fix the problem?

    The error message does not give the source line where the problem is.
    Without the line number and the type of error, it is hard to know what the problem is.

    Yes, I understood, but it didn't fix the problem.
    getaccess(randomNo,realNo); - cannot find symbol variable randomNo and realNo.

    Should I post the whole code?

    cannot find symbol variable randomNo and realNo.
    Where are those two variables defined? The compiler can not find their definitions in scope (within the same pair of {}s) at the line where they are being used.

    String realNo = getrealNo();

    OMG, i'm so ...
    boolean access = getaccess(randomNo,realNo) should be the last one called.
    Thanks a lot.

    Define and assign BEFORE using.
