Errors compiling Java program

Everytime I try to compile the following errors in this type of code and I dont know why

Welcome to CodeRanch!

Your subject title is confusing. In Java, we don't really refer to source code as "script". And if you meant to write JavaScript, that's a completely unrelated language that has nothing to do with Java.

What error messages is the compiler giving you?

Without looking at your code too closely, I can see that you've written Public and Void a couple of times. It's public and void, without capital letters.

these are the complier error messages that I receive are

not a statement

';' expected

illegal start of expression

and reaching end of file while parsing

Illegal start of statement and reached end of file are both probably caused by having too many {s somewhere. Look at lines 96‑101.

The keywords are public and void, not Public and Void. The P/p or V/v difference is significant.

Yeah, that's because you have stray semi-colons, missing parentheses and other typos in the code. The compiler should tell you exactly where.

Have you gone through the Java tutorials yet? If not, I suggest you take some time to do so: https://docs.oracle.com/javase/tutorial/
