哪位大神用JAVA把这2题做出来，尽量写的简单易懂些，我才刚学类和对象，才学完无参方法，有参还没学

class Customer
{
private double Saving=100;
public double getSaving()
{
return Saving;
}

}
public class Test
{
public static void main(String[] args)
{
Customer c1=new Customer();
System.out.println("账户余额为:"+c1.getSaving());
}
}

import java.util.Scanner;
public class Test
{
public static void main(String[] args)
{ Scanner in=new Scanner(System.in);
int money=2000;
int n;
int count=0;
boolean b=true;
System.out.print("请猜测\"公主电动车\"的价格:");
while(true)
{
n=in.nextInt();
if(n>money)
{ if(count!=3)
{
System.out.println("再小点!");
System.out.println();
System.out.print("再猜一次吧:");
}
}
else if(n { if(count!=3)
{
System.out.println("再大点!");
System.out.println();
System.out.print("再猜一次吧:");
}
}
else
{
b=false;
System.out.println("猜对了");
}
count+=1;
if(count==4)
{ System.out.println();
System.out.println("4次内没有猜对，下次再努力吧！");
break;
}

}
}
}

public class account
{
    private int money;
    pubilc  int getMoney(){
        return this.money;

    //想知道第二题吗？
}
