    One big problem with your code is that it is not indented properly making it very hard to read and understand. The code inside of every {} pair should be indented at least 3 spaces. Look at the many examples posted on this forum.

    number = number++1;

    That is not legal syntax. If you want to increment the variable by 1 then simply use number++;

    In future do not mark your problem ASAP. You are no more important than anyone else asking for help. You will or will not get help depending upon the willingness of the volunteers coming to the forum. In my case I am less likely to help people who say ASAP or URGENT thus reducing your chances of getting help not increasing it.

    class, interface, or enum expected
    Check that all {s have a paired } before line 206
    Look at each method and check that its beginning { has an ending }

    It helps a lot if you align the source line with the beginning { vertically with the ending }

    Also if you label each ending } with what it is ending like the name of the method or class or if or while.

    Another approach is to comment out sections of your code by using /* and */ to see where this error is.
    For example comment out methods.

    Well, these all 17 errors are mostly related to non-positioned closing brace '}'
    Look carefully into your code, either use some editor(Eclipse, IntelliJIDea, NetBeans, JetBrains etc) as Editors guide you with color markers of starting and ending braces.

    find the missing brace?
    Many IDEs editors have a menu item to help you find the paired {}s. Place your curosor on one { press a key combination and the cursor is moved to the pairing }. On my editor I press: CTL + ]

    Otherwise print out the source file and use a pen. Circle a { and draw a line to its pairing }.

    Start at an inner most pair of {} and work out to the outer most pair.

    Well, your code doesn't only have one error but actually alot of errors, although it shows only one error for now, but try removing the brace as i can't figure out your code actually, it's too bad. I have looked over the code and found it difficult to manage. Atleast, no one will spend hours to remove this brace for you. So, use any IDE to figure this out by yourself as it's your code and no one can understand it better than you.
    Your code also has problems of duplicate functions.
