Java中的类 isLocalClass() 方法及示例

Java.lang.Class 类isLocalClass()方法用于检查该类是否为Local 类。如果这个 Class 是 Local 类,则该方法返回 true。否则返回 false。
句法:

public boolean isLocalClass()

参数:此方法不接受任何参数。
返回值:如果这个类是本地类,这个方法返回。否则返回false
下面的程序演示了 isLocalClass() 方法。
示例 1:

Java
// Java program to demonstrate isLocalClass() 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 localClass
        // using isLocalClass() method
        System.out.println("Is Test an localClass: "
                           + myClass.isLocalClass());
    }
}


Java
// Java program to demonstrate isLocalClass() method
 
public class Test {
 
    public static void main(String[] args)
        throws ClassNotFoundException
    {
 
        class A {
        }
 
        // returns the Class object for A
        Class myClass = A.class;
 
        // Check if myClass is an localClass
        // using isLocalClass() method
        System.out.println("Is A an localClass: "
                           + myClass.isLocalClass());
    }
}


输出:
Class represented by myClass: class Test
Is Test an localClass: false

示例 2:

Java

// Java program to demonstrate isLocalClass() method
 
public class Test {
 
    public static void main(String[] args)
        throws ClassNotFoundException
    {
 
        class A {
        }
 
        // returns the Class object for A
        Class myClass = A.class;
 
        // Check if myClass is an localClass
        // using isLocalClass() method
        System.out.println("Is A an localClass: "
                           + myClass.isLocalClass());
    }
}
输出:
Is A an localClass: true
