PROBLEM:

“Class, Interface, Or enum Expected” error arises due to additional curly braces at end of Java program.

Considering an example where the file is named as wikitechy.java

public class wiki {     
        public static void main(String[] args) {
            System.out.println(“Wikitechy welcomes you!");
        }
    }
    }

    1 error found:
    File: wikitechy.java  [line: 6]
    Error: class, interface, or enum expected

SOLUTION 1

We need to notice that two curly braces at the end of the program are at the same indentation level, which cannot happen in a valid program. So, if you get this same Class, interface or enum expected error next time, first check if there is an additional curly braces at end of program.

SOLUTION 2

Simply delete one of the curly braces for the code to compile properly and check the code below :

 public class wiki {     
        public static void main(String[] args) {
            System.out.println(“Wikitechy welcomes you!");
        }
    }

SOLUTION 3

We can also identify this kind of error by pressing CTRL-A (to highlight the entire program) and then TAB (to correctly indent the highlighted code)

PROBLEM:

Compiler error: “class, interface, or enum expected”

Considering an example where the file is named as wikitechy.java

import java.util.Random;
import java.Math.*;
import javax.swing.JOptionPane;
public static void wiki(String args[])
{
    // a bunch of code
}

SOLUTION 4

In this program,  class declaration(wiki) is missing . Check the Java code below :

public class wiki{                             
   public static void wiki(String args[]){ ... }
}
