Java Class isLocalClass()方法及示例

Java Class isLocalClass()方法及示例

java.lang.Class类isLocalClass() 方法用于检查该类是否为本地类。如果该类是本地类,该方法返回true。否则返回false。
语法:

public boolean isLocalClass()

参数: 该方法不接受任何参数。

返回值: 如果这个类是本地类,该方法返回 true 。否则返回 false

下面的程序演示了isLocalClass()方法。

示例1:

// 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());
    }
}

输出

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

例2:

// 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
