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());
}
}
输出
Is A an synthetic: false
