Java中的类 isLocalClass() 方法及示例
Java.lang.Class 类的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,这个方法返回真。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
