原文:https://www . geeksforgeeks . org/class-togenericstring-method-in-Java-with-examples/
java.lang.Class 类 的 toGenericString() 方法用于将该类的实例转换为字符串表示形式,以及关于修饰符和类型参数的信息。此方法返回形成的字符串表示形式。
语法:
public String toGenericString()
参数:此方法不接受任何参数。
返回值:这个方法返回这个对象的字符串表示。
下面的程序演示了 toGenericString()方法。
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
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
