public class Test{
public static void Temp(String ClassName,String MethodName,String args)
{
.................................................
}
public static void main(String args[])
{
Temp("Hello","Demo","nihao");
}
}
class Hello
{
public void Demo(String args)
{
System.out.println("Hello"+args);
}
}
写一个方法：public void Temp(String ClassName,String MethodName,String args)，使得这个方法能够实现调用，其中ClassName为类名，MethodName为方法名，args参数。例如：Temp("Hello","Demo","nihao");

- Java code
import java.lang.reflect.Method;public class Test1 { public static void Temp(String ClassName, String MethodName, String args) throws Exception { Class c = Class.forName(ClassName); Method method = c.getDeclaredMethod(MethodName, String.class); Object obj = c.newInstance(); method.invoke(obj, args); } public static void main(String args[]) throws Exception { Temp("Hello", "Demo", "nihao"); }}class Hello { public void Demo(String args) { System.out.println("Hello" + args); }}
