Getting Class name in a static method in Java

Finding the name of a Class in Java from within a static method

One of our regular visitors (Ranvijay) had asked it a couple of days back. Though, the code is pretty straightforward, I think it might help few others if posted as an article.

One of the many possible ways of finding the name of the class in Java from within a static method is by using a static nested class, which will have a public instance method returning the class name of the enclosing class (in our case the class where we have the particular static method).

public class GetClassNameInStaticMethod {

public static void main(String[] args) {
// Calling a Static Method
System.out.println("Current Class Name: " + getCurClassName());
public static String getCurClassName(){
return (new CurClassNameGetter()).getClassName();

//Static Nested Class doing the trick
public static class CurClassNameGetter extends SecurityManager{
public String getClassName(){
return getClassContext()[1].getName();


Current Class Name: GetClassNameInStaticMethod
