java的反射问题

public class ReflectTester {     public static void main (String[] s) throws Exception     {     	ReflectTester rt=new ReflectTester();         rt.copy(new Test());     }     public Object copy(Object obj) throws Exception{     	Class classType=obj.getClass();     	Constructor cons=classType.getConstructor(int.class,String.class);     	Object ob=cons.newInstance(new Object[]{new Object[]{}});     	Field[] f=classType.getDeclaredFields();     	for(Field fi : f){     		String name=fi.getName();     		String firstLetter=name.substring(0,1).toUpperCase();     		String getMethodName="get"+firstLetter+name.substring(1);     		String setMethodName="set"+"get"+firstLetter+name.substring(1);     		Method getMethod=classType.getMethod(getMethodName, new Class[]{});     		Method setMethod=classType.getMethod(setMethodName,new Class[]{fi.getType()} );     		Object value =getMethod.invoke(obj, new Object[]{});     		setMethod.invoke(ob, new Object[]{value}); }     	return null;     } } class Test{ 	private int id; 	private String name; 	private int age; 	Test(){ 	} 	Test(int i,String n){ 		this.id=i; 		this.name=n; 	} 	public int getId() { 		return id; 	} 	public void setId(int id) { 		this.id = id; 	} 	public String getName() { 		return name; 	} 	public void setName(String name) { 		this.name = name; 	} 	public int getAge() { 		return age; 	} 	public void setAge(int age) { 		this.age = age; 	} 这段代码中Method getMethod=classType.getMethod(getMethodName, new Class[]{});的getMethodName不应该是getId的吗？
