我的类编译的时候怎么找不到文件啊，一个文件夹下其他文件又可以，javac编译的
class SavingsAcount{
private double balance;// 存储余额
// private double interest;
private double rate;
public SavingsAcount( double initia, double rate ){ //构造一个有初始余额账户
this.balance = initia;
this.rate = rate;
}
//在账户存款
public void deposit( double amount ){
this.balance = this.balance + amount;
}
//在账户取款
public void withdraw( double amount ){
this.balance = this.balance - amount;
}
public double getBalance(){
return this.balance;
}
public double addInterest( ){
double interest = this.balance * this.rate ;
return interest;
}
}//请哪位帮我看看，顺便帮我编译下
