JavaMadeSoEasy.com (JMSE): Resolve error: Class names, 'className', are only accepted if annotation processing is explicitly requested

You are here : Home / Core Java Tutorials /

In this java tutorial we will solve error: Class names, 'className', are only accepted if annotation processing is explicitly requested

Contents of page >

1) Why error: Class names, ‘className’, are only accepted if annotation processing is explicitly requested occurs>
2) First create below java program in E:\MyJavaProgram.java>
3) Let’s try to create class file of above program using CMD, Go to CMD, and try to compile java file by typing below command to produce error: Class names, ‘className’, are only accepted if annotation processing is explicitly requested >

Way 1 to produce error: Class names, ‘className’, are only accepted if annotation processing is explicitly requested >
Way 2 to produce error: Class names, ‘className’, are only accepted if annotation processing is explicitly requested >
Way 3 to produce error: Class names, ‘className’, are only accepted if annotation processing is explicitly requested >
Way 4 to produce error: Class names, ‘className’, are only accepted if annotation processing is explicitly requested >

4) For solving this error: Class names, 'className', are only accepted if annotation processing is explicitly requested

1) Why error: Class names, ‘className’, are only accepted if annotation processing is explicitly requested occurs>

Extension .java was missing during compilation of java file.
.Java was used, J was capital, it should have been .java during compilation of java file.
jav was used, it should have been .java
class name used was incorrect during compilation of java file.

Now let’s discuss all above ways in detail.

2) First create below java program in E:\MyJavaProgram.java>

public class MyJavaProgram{

public static void main(String[] args) {

System.out.println("This is MyClass");

}

3) Let’s try to create class file of above program using CMD, Go to CMD, and try to compile java file by typing below command to produce error: Class names, ‘className’, are only accepted if annotation processing is explicitly requested >

Way 1 to produce error: Class names, ‘className’, are only accepted if annotation processing is explicitly requested >

E:\>javac MyJavaProgram

error: Class names, 'MyJavaProgram', are only accepted if annotation processing is explicitly requested

1 error

Reason of error :

Extension .java was missing.

Way 2 to produce error: Class names, ‘className’, are only accepted if annotation processing is explicitly requested >

E:\>javac MyJavaProgram.Java

error: Class names, 'MyJavaProgram.Java', are only accepted if annotation processing is explicitly requested

1 error

Reason of error :

.Java was used, J was capital, it should have been .java

Way 3 to produce error: Class names, ‘className’, are only accepted if annotation processing is explicitly requested >

E:\>javac MyJavaProgram.jav

error: Class names, 'MyJavaProgram.jav', are only accepted if annotation processing is explicitly requested

1 error

Reason of error :

.jav was used, it should have been .java

Way 4 to produce error: Class names, ‘className’, are only accepted if annotation processing is explicitly requested >

E:\>javac MyJavaProg

error: Class names, 'MyJavaProg', are only accepted if annotation processing is explicitly requested

1 error

Reason of error :

class name used was incorrect (it should have been MyJavaProgram)

And

.java was missing

4) For solving this error: Class names, 'className', are only accepted if annotation processing is explicitly requested

E:\>javac MyJavaProgram.java

E:\>

And problem is resolved, class file is created in E:\MyJavaProgram.class
