m.PrintAccuntMeg();
m.saveMonye(100.0);
m.PrintAccuntMeg();
m.getMonye(50.0);
m.PrintAccuntMeg();
}
}
编译的时候在这句BankAccunt m=new BankAccunt("zyb",100.0,0.08);
说找不到符号
这是为什么？
----------------解决方案--------------------------------------------------------
难道大家都不知道错在那里了吗
----------------解决方案--------------------------------------------------------
拜托，把异常信息贴出来阿
----------------解决方案--------------------------------------------------------
void BankAccunt(String m,Double q,Double r)这是一个构造函数，不能用 void,把void去掉
----------------解决方案--------------------------------------------------------
void BankAccunt(String m,Double q,Double r)//构造方法有这种表示吗?不需要返回类型 .
class BankAccunt
{
String m_sName;
double m_dBalance;
double m_dRate;
BankAccunt(String m,double q,double r)//Double 表示的是对象.而double才是表示类型;
{
m_sName=m;
m_dBalance=q;
m_dRate=r;
}
double getBalance()
{
return this.m_dBalance;
}
double getRate()
{
return this.m_dRate;
}
void setRate(double l)
{
m_dRate=l;
}
double saveMonye(double c)
{
return m_dBalance+=c;
}
double getMonye(double t)
{
return m_dBalance-=t;
}
void PrintAccuntMeg()
{
System.out.println(m_sName);
System.out.println(m_dBalance);
System.out.println(m_dRate);
}
}
public class SimpleAccunt{
public static void main(String[] args)
{
BankAccunt m=new BankAccunt("zyb",100.0,0.08);
m.PrintAccuntMeg();
m.saveMonye(100.0);
m.PrintAccuntMeg();
m.getMonye(50.0);
m.PrintAccuntMeg();
}
}

3 楼 4楼 速度蛮快的哦。
我刚看题目的时候你们还没发言.等我把程序帖出来 你们都把问题解决了.哎.
