Re: Big errors i got plz help me out illegal type of expression type,
 

Yes. Because you have no main method - you need to put any code (other than variable declarations) inside methods. The main method is the method that runs when you first start your program, *edit*


Oops, nevermind - I see that you do have a main method. For statements like String lang, then lang = "abc", you would need to initially just say String lang = "abc"; . . and what I said about only having variable declarations still stands. lang = "abc" is an assignment statement, and thus, isn't allowed unless you do it inside of a method.

Re: Big errors i got plz help me out illegal type of expression type,
 

edit, sorry guys. Combined the two posts.

Re: Big errors i got plz help me out illegal type of expression type,
 

I am not satisfied with this answer

Re: Big errors i got plz help me out illegal type of expression type,
 

It gives me errors like previous one

Re: Big errors i got plz help me out illegal type of expression type,
 

Satisfied or not, he's right. Everything except variable declarations have to be inside a method. Post your latest code, with code=java tags.

Guys i changed the code now i get 3 errors plz HLP me out errors are after the code

Re: Big errors i got plz help me out illegal type of expression type,
 

Everything except variable declarations still have to be inside a method. Indent your code so you can see where methods and classes end. Your errors start immediately after the end of the init method because the following code isn't in a method.
This would have been obvious to you with proper indentation and code tags.

Re: Big errors i got plz help me out illegal type of expression type,
 

ps: If you have code that looks like this:

catch(Exception ee) {}

then what you are saying is: "if my code goes wrong I do not want to know why or where it happened. Please just stop executing and give me no help at all".
Try replacing all those with

catch(Exception ee) {

  ee.printStackTrace();

}

so you know what's happening.

Re: Big errors i got plz help me out illegal type of expression type,
 

thnks my code is now running
