学习面向对象中依赖关系，修改程序出现问题，不会建set,get感觉（新手啊，然后程序都敲好了）
程序代码：package public class BankId {
//声明属性
private String id;
private String pwd;
private double balance;
//声明数组，保存日志
private String[] logInfo = new String[3];
private int index;
//有三个参数的构造方法
BankId(String id,String pwd,double balance){
//System.out.println("BankId(String id,String pwd,double balance)");
this.id = id;
this.pwd=pwd;
this.balance = balance;
}
//查看余额
double getBalance(){
return balance;
}
//存款活期
public void deposit(double amount){
balance += amount;
Logger.log(this,"日志，存款成功"+amount);
//if(inde>2){
// inde = 0;
//}
//logInfo[inde]="活期的存款为："+amount;
//inde++;
}
//存款 定期
public void deposit(double amount, int term){
balance += amount;
Logger.log(this,"日志，存款成功"+amount);
//if(inde>2){
// inde = 0;
//}
//logInfo[inde]="活期的存款为："+amount;
//inde++;
}
//取款，不能透支
public boolean withdraw(double amount){
if (amount > balance){
Logger.log(this,"日志，存款失败"+amount);
//if(inde>2){
// inde = 0;
//}
//logInfo[inde]="取款失败："+amount;
//inde++;
return false;
}else{
balance -= amount;
Logger.log(this,"日志，存款成功"+amount);
//if(inde>2){
// inde = 0;
//}
//logInfo[inde]="取款成功："+amount;
//inde++;
return true;
}
}
//返回日志数组
public String[] getlogInfo(){
return this.logInfo;
}
}程序代码：package class Logger {
public static void log(BankId account,String msg){
String[] logInfo =account.getlogInfo();
int index = account.getindex();
if(index>2){
index=0;
}
logInfo[index]=msg;
index++;
account.setindex(index);//就setloginfo和setloginfo没有前面定义
}
public static void printLog(BankId account){
String[] LogInfo = account.getlogInfo();
for (String s:logInfo){
if(s!=null){
System.out.println("日志"+s);
}
else{
break;
}
}
}
}程序代码：package public class TestBankId {
/**
* @param args
*/
public static void main(String[] args) {
BankId account1 = new BankId("312214","231244",5200);
account1.deposit(2222);
account1.withdraw(1400);
account1.withdraw(1400);
String[] logInfo =account1.getlogInfo();
Logger.printLog(account1);
}
}就是这个程序时让我修改“日志保存”运用依赖关系，建一个类中引用。但是我有点不会，缺了一个set,get感觉。希望大神帮我看看，谢谢
