Java Class isSynthetic()方法及实例

java.lang.Class类 的 isSynthetic() 方法是用来检查该类是否为合成类。如果该类是合成类，该方法返回true。否则返回false。
语法

public boolean isSynthetic()

参数： 该方法不接受任何参数。

返回值： 如果这个类是合成类，该方法返回 true 。否则返回 false 。

下面的程序演示了isSynthetic()方法。

例1 :

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

输出

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

例2 :

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