一个异常处理的问题
package com.Test;
class PasswordException extends Exception{
public String toString(){
return("PasswordException:密码错误");
}
}

class OverTopException extends Exception{
public String toString(){
return("OverTopException:取款超过限额");
}
}
class BlanceLackException extends Exception{
public String toString(){
return("BlanceLackException:余额不足");
}
}

public class Bank {

/**
* @param args
*/
private int top;
private int balance;
private static boolean exceptionSign;
public Bank(int top,int balance){
this.top = top;
this.balance = balance;
this.exceptionSign = false;

}
public void fetchMoney(String password,int money)throws
OverTopExeption,PasswordException,BalanceLackException{
if(password.length()==0)throw new PasswordException();
if(money>top)throw new OverTopException();
if(money>balance)throw new BalanceLackException();
 

}
public static void main(String[] args) {
// TODO Auto-generated method stub
Bank bank = new Bank(2000,1000);
try{
bank.fetchMoney("1", 500);
bank.fetchMoney(" ",1000);
}catch(PasswordException e){
exceptionSign = true;
System.out.println(e);
}catch(OverTopException e){
exceptionSign = true;
System.out.println(e);
}catch(BalanceLackException e){
exceptionSign = true;
System.out.println(e);
}finally{
if(exceptionSign)System.out.println("有错误产生");
else System.out.println("操作完成");
}


}

}




这是一个模拟银行取款业务 的程序 ，不知道哪里错了，求大神指点

都是拼写错误，你好好检查下fetchMoney和main方法里，那些Exception是否有拼写错误。
package com.Test;
class PasswordException extends Exception{
public String toString(){
return("PasswordException:密码错误");
}
}

class OverTopException extends Exception{
public String toString(){
return("OverTopException:取款超过限额");
}
}
class BlanceLackException extends Exception{
public String toString(){
return("BlanceLackException:余额不足");
}
}

public class Bank {

/**
* @param args
*/
private int top;
private int balance;
private static boolean exceptionSign;
public Bank(int top,int balance){
this.top = top;
this.balance = balance;
this.exceptionSign = false;

}
public void fetchMoney(String password,int money)throws
OverTopExeption,PasswordException,BalanceLackException{
if(password.length()==0)throw new PasswordException();
if(money>top)throw new OverTopException();
if(money>balance)throw new BalanceLackException();
 

}
public static void main(String[] args) {
// TODO Auto-generated method stub
Bank bank = new Bank(2000,1000);
try{
bank.fetchMoney("1", 500);
bank.fetchMoney(" ",1000);
}catch(PasswordException e){
exceptionSign = true;
System.out.println(e);
}catch(OverTopException e){
exceptionSign = true;
System.out.println(e);
}catch(BalanceLackException e){
exceptionSign = true;
System.out.println(e);
}finally{
if(exceptionSign)System.out.println("有错误产生");
else System.out.println("操作完成");
}


}

}
