The getEnclosingMethod() method of java.lang.Class class is used to get the enclosing methods of this class. The method returns the enclosing methods of this class if this class is a local class or anonymous class declared in that method. Else this method returns null.
Syntax:
public Method getEnclosingMethod()
Parameter: This method does not accept any parameter.
Return Value: This method returns the enclosing methods of this class if this class is a local class or anonymous class declared in that method. Else this method returns null.

Below programs demonstrate the getEnclosingMethod() method.
Example 1:
Java
import java.util.*;
public class Test {
public static void main(String[] args)
throws ClassNotFoundException
{
Class myClass = Class.forName("Test");
System.out.println("Class represented by myClass: "
+ myClass.toString());
System.out.println("EnclosingMethod of myClass: "
+ myClass.getEnclosingMethod());
}
}
|
Output: Class represented by myClass: class Test
EnclosingMethod of myClass: null
Example 2:
Java
import java.util.*;
class Main {
public Object obj;
public Object func()
{
class Arr {
};
return new Arr();
}
public static void main(String[] args)
throws ClassNotFoundException
{
Main t = new Main();
Class myClass = t.func().getClass();
System.out.println("getEnclosingMethod of myClass: "
+ myClass.getEnclosingMethod());
}
}
|
Output: EnclosingConstructor of myClass: public java.lang.Object Main.func()
