又来一道面试题

Question

1英镑=12先令
1先令=20便士写个方法 把指定的便士转换成 英镑,先令,便士 的格式输出
如:272 便士 = 1,1,12的格式

Answer 1

public class trans 
{
private int pounds;
private int shillings;
private int pence;

public trans(int pence)
{
shillings=(int)pence/20;
this.pence=pence%20;
shillings=(int)pence/20;
pounds=shillings/12;
shillings=shillings%12;
}
public String toString()
{
return(pounds+","+shillings+","+pence);
} public static void main(String[] args)
{
System.out.println(new trans(272));
}
}

Answer 2

public static String getA(int i){
        
        StringBuffer bf = new StringBuffer();
        int j = i/240;
        
        int k = (i-j*240)/20;
        
        int m = i-j*240-k*20;
        bf.append(j).append(",").append(k).append(",").append(m);
        return bf.toString();
        
    }

Answer 3

这种面试题是不是太简单了啊?看不懂二楼和四楼, 怎么还要减?public class CurTrans {
    public static double PenniesToShillings(double pennies) {
        return pennies/20;
    }
    public static double PenniesToPounds(double pennies) {
        return pennies/240;
    }
    public static void main(String[] args) {
        if(args.length > 0) {
            double pennies = Double.parseDouble(args[0]);
            System.out.println(pennies + " pennies is " + 
                PenniesToPounds(pennies) + " pounds, " + 
                PenniesToShillings(pennies) + " shillings.");
        }
    }
}

Answer 4

这道题是非常简单的，只要理清了逻辑关系问题就OK了：
思路：写个转换便士的方法，方法接收所有的便士数，由于1英磅=240便士，即可得到英磅值，1先令=20便士即可得到先令值，剩下的就是便士数咯。
测试源代码：
public class Transfer
{
  public static void main(String[] s)
  {
    int pennies = 72;
    transferToPennies(pennies);
  }
  
  static void transferToPennies(int p)
  {
    System.out.println((int)p/240 + " pounds," + (int)(p%240)/20 + " shillings," + (p%240)%20 + " pennies");
  }
}
