Question

java 问题，希望高手们指点迷津

public class Clock
{
int hour;
int miunte;
int second;
public void setTime(int newH,int newM,int newS)
{
hour=int newH;
minute=int newM;
second=int newS;
}
public void showtime()
{
systemm.out.println(hour+":"+miunte+":"+second);
}
}

Answer 1

public class Clock
{
int hour;
int miunte;
int second;
public void setTime(int newH,int newM,int newS)
{
hour=newH; //int 去掉，直接将参数赋值给属性
miunte=newM; //同上，miunte你也拼错了
second=newS; //同上
}
public void showtime()
{
System.out.println(hour+":"+miunte+":"+second); //System拼错了
}
}

Answer 2

public class Clock
{
int hour;
int miunte;
int second;
public void setTime(int newH,int newM,int newS)
{
hour=newH;
minute=newM;
second=newS;
}
public void showtime()
{
systemm.out.println(hour+":"+miunte+":"+second);
}
//要想让这个类运行起来,必须有这个main方法才可以的.
public static void main(String[] args){
Clock clock = new Clock();
clock.setTime(12,01,03);
clock.showtime();
}
}

Answer 3

整理后代码 我没有删除你原来的错误代码 你自己对比一下
public class Clock {
int hour;
int miunte;
int second;

public void setTime(int newH, int newM, int newS) {
// hour=int newH;
// minute=int newM;
// second=int newS;
hour = newH;
miunte = newM;
second = newS;
}

public void showtime() {
// systemm.out.println(hour + ":" + miunte + ":" + second);
System.out.println(hour + ":" + miunte + ":" + second);
}

//追加部分
public static void main(String[] args) {
Clock c = new Clock();
c.setTime(1,2,3);
c.showtime();
}
}

Answer 4

具体代码 就不写了
总结下错误吧
1 LZ对实参和形参的不是很理解 在setTime（）方法中 newH前面没有int的
2 整个方法 如果你要对它进行编译 是不是缺了个主方法？
3 showtime方法中 system拼写错了

Answer 5

public class Clock
{
int hour;
int miunte;
int second;
public void setTime(int newH,int newM,int newS)
{
hour= newH;\\这里不应该有int
minute= newM;
second= newS;
}
public void showtime()
{
systemm.out.println(hour+":"+miunte+":"+second);\\System.out
}
}
