How to Fix Error: “Class, Interface, or Enum Expected” ?

The braces in java are served as a scope limit. The beginning and end of a code block are indicated by curly brackets.

Curly brackets cause the compile-time error known as the class interface or enum expected error in Java. This issue typically happens when the program ends with an extra curly brace.

Since everything in Java is programmed inside a class, interface, or enum, if you close the curly bracket for one class and add another, the compiler will assume that another class is starting and will complain about the class, interface, or enum keyword, as illustrated in the following program:

because of extra braces.

Misplaced Curly Braces

The root cause of the “class, interface, or enum expected” error is typically a misplaced curly brace “}”. This can be an extra curly brace after the class. It could also be a method accidentally written outside the class.

Code Explanation The following error will be raised

To solve this error simply remove extra brace

Function Outside Class (Intro+ Add Code Example Ti Fix Error)

A method present outside of a class may also be the cause of this problem. The compilation process will fail since this method does not belong to any class. Moving the method within the class will fix this issue.

Code Explanation In Above code method1 is outside of class classb this will raise error.To solve this placed method1 inside of classb.

Multiple Package

In a Java file, only one package can be declared. The expected compilation error for a class, interface, or enum will occur if we have more packages than necessary.

Code Explanation To solve error import only one package.Each source file can only have one package statement, and it must apply to all of the file's types.
