Question

Why is this code not working? I created the two different Java files. One of them named Test.java and the other GuessgameTest.java. On Test.java, it keeps displaying the error :

----jGRASP exec: javac -g GuessgameTest.java

Test.java:138: error: reached end of file while parsing
}
^
1 error

----jGRASP wedge2: exit code for process is 1.
----jGRASP: operation complete.

Please Help!

Getting error.. Add the section that makes the program run...

import javax.swing.JFrame;

public class GuessgameTest{
public static void main(String args[]) throws Exception{
Test guessgame = new Test();
guessgame.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE );
guessgame.setSize(550, 150);
guessgame.setVisible(true);
}
}

Explanation / Answer

It is because you have forgotten one closing curly braces ( ' } ') . Please make sure that you add one in the required place. I have checked it on ideone and found that one closing curly brace is expected. Hope this solves your problem
