原文:https://www . geesforgeks . org/class-is memberclass-method-in-Java-with-examples/

方法检查这个类是否是成员类。如果此类是成员类,则方法返回 true。否则返回 false。

语法:

public boolean isMemberClass()

参数:此方法不接受任何参数。

返回值:如果这个类是成员类,这个方法返回。否则返回

下面的程序演示了 isMemberClass()方法。

例 1:

// Java program to demonstrate isMemberClass() method

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());

        // Check if this class is an memberClass
        // using isMemberClass() method
        System.out.println("Is Test an memberClass: "
                           + myClass.isMemberClass());
    }
}

输出:

Class represented by myClass: class Test
Is Test an memberClass: false

例 2:

// Java program to demonstrate isMemberClass() method

public class Test {

    class A {
    }

    public static void main(String[] args)
        throws ClassNotFoundException
    {

        // returns the Class object for A
        Class myClass = A.class;

        // Check if myClass is an memberClass
        // using isMemberClass() method
        System.out.println("Is A an memberClass: "
                           + myClass.isMemberClass());
    }
}

输出:

Is A an memberClass: true
