类是 Java 中的综合()方法,带有示例

原文:https://www . geeksforgeeks . org/class-isssynicious-method-in-Java-with-examples/

Java . lang . Classissynamic()方法用于检查该类是否为合成类。如果此类是合成类,则方法返回 true。否则返回 false。 语法:

public boolean isSynthetic()

参数:此方法不接受任何参数。 返回值:如果这个类是合成类,这个方法返回。否则返回。 下面的程序演示了 isSynthetic()方法。 例 1:

Java 语言(一种计算机语言,尤用于创建网站)

// 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());
    }
}

Output: 

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

例 2:

Java 语言(一种计算机语言,尤用于创建网站)

// 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());
    }
}

Output: 

Is A an synthetic: false
