The getEnclosingClass() method of java.lang.Class class is used to get the enclosing class of this class. The method returns the enclosing class of this class, if this class is a local class or anonymous class declared in that class. Else this method returns null.
Syntax:
public Class getEnclosingClass() throws SecurityException
Parameter: This method does not accept any parameter.
Return Value: This method returns the enclosing class of this class if this class is a local class or anonymous class declared in that class. Else this method returns null.
Exception This method throws SecurityException if a security manager is present and the security conditions are not met.
Below programs demonstrate the getEnclosingClass() method.
Example 1:
// Java program to demonstrate getEnclosingClass() method import java.util.*;
public class Test {
public static void main(String[] args)
throws ClassNotFoundException
{
// returns the Class object for this class
Class myClass = Class.forName("Test");
System.out.println("Class represented by myClass: "
+ myClass.toString());
// Get the enclosing class of myClass
// using getEnclosingClass() method
System.out.println("EnclosingClass of myClass: "
+ myClass.getEnclosingClass());
}
} |
Class represented by myClass: class Test EnclosingClass of myClass: null
Example 2:
// Java program to demonstrate getEnclosingClass() method import java.util.*;
class Main {
public Object obj;
Main()
{
class Arr {
};
obj = new Arr();
}
public static void main(String[] args)
throws ClassNotFoundException
{
Main t = new Main();
// returns the Class object
Class myClass = t.obj.getClass();
// Get the enclosing class of myClass
// using getEnclosingClass() method
System.out.println("EnclosingClass of myClass: "
+ myClass.getEnclosingClass());
}
} |
EnclosingClass of myClass: class Main
