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.
Exception This method throws SecurityException if a security manager is present and the security conditions are not met.
Below programs demonstrate the getEnclosingMethod() method.
Example 1:
Java
// Java program to demonstrate getEnclosingMethod() methodimport 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 methods of myClass // using getEnclosingMethod() method System.out.println("EnclosingMethod of myClass: " + myClass.getEnclosingMethod()); }} |
Class represented by myClass: class Test EnclosingMethod of myClass: null
Example 2:
Java
// Java program to demonstrate getEnclosingMethod() methodimport 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(); // returns the Class object Class myClass = t.func().getClass(); // Get the enclosing constructors of myClass // using getEnclosingConstructor() constructor System.out.println("getEnclosingMethod of myClass: " + myClass.getEnclosingMethod()); }} |
EnclosingConstructor of myClass: public java.lang.Object Main.func()
