Question

Java如何获取方法的参数名称

Answer 1

package test;

import java.lang.reflect.Method;

public class TTT {
public static void main(String[] args) {
Class c = Test.class;
Method[] methods =c.getDeclaredMethods();
for (Method method : methods) {
System.out.print("方法的返回值"+method.getReturnType().getName());
System.out.print(" 方法名："+method.getName()+"(");
Class[] paraTypes = method.getParameterTypes();
for (Class class1 : paraTypes) {
System.out.print("参数类型："+class1.getSimpleName()+",");
}
System.out.println(")");
}

}
}

class Test
{
public void say(String word)
{
System.out.println(word);
}

public void say(String word,int n)
{
for(int i=0;i<n;i++){

System.out.println(word);
}
}

}
