下面的程序演示了toGenericString()方法。

示例1:

// Java program to demonstrate toGenericString() method 
  
public class Test { 
    public static void main(String[] args) 
        throws ClassNotFoundException 
    { 
        // returns the Class object for the class 
        // with the specified name 
        Class c1 = Class.forName("java.lang.String"); 
  
        System.out.print("Class represented by c1: "); 
  
        // toGenericString method on c1 
        System.out.println(c1.toGenericString()); 
    } 
}

输出：

Class represented by c1: public final class java.lang.String

示例2:

// Java program to demonstrate toGenericString() method 
  
public class Test { 
    public static void main(String[] args) 
        throws ClassNotFoundException 
    { 
        // returns the Class object for the class 
        // with the specified name 
        Class c2 = int.class; 
        Class c3 = void.class; 
  
        System.out.print("Class represented by c2: "); 
  
        // toGenericString method on c2 
        System.out.println(c2.toGenericString()); 
  
        System.out.print("Class represented by c3: "); 
  
        // toGenericString method on c3 
        System.out.println(c3.toGenericString()); 
    } 
}

输出：

Class represented by c2: int
Class represented by c3: void
