示例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
