在java中十进制转换为二进制具有倒车订单的相关问题 [英] Converting decimal to binary in java having trouble with reversing order

问题描述

哎，所以我把我的第一个CS当然永远在我的大学其在java中任教。我在遇到麻烦十进制转换为二进制。我似乎能够得到正确的输出，但其以相反的顺序，我不知道如何把它放在正确的顺序，这里就是我codeD到目前为止，

 进口的java.util。*;
公共类{六硼化镧
公共静态无效的主要（字串[] args）{
扫描仪输入=新的扫描仪（System.in）;
   System.out.print（输入一个十进制数转换为二进制：）;
   INT X = input.nextInt（）;
   诠释Ÿ;
   串Y1 =;
   而（X！= 0）{
       Y = X％2;
       X = X / 2;
       Y1 = Integer.toString（Y）;
       System.out.print（Y1 +）;
     }
}
}
 

解决方案

看来你是显示仅在正确的顺序输出。但是如果你想扭转目前的输出，你可以使用下面code：

 扫描仪输入=新的扫描仪（System.in）;
        System.out.print（输入一个十进制数转换为二进制：）;
        INT X = input.nextInt（）;
        诠释Ÿ;
        串Y1 =;
        串反向=;
        而（X！= 0）{
           Y = X％2;
           X = X / 2;
           Y1 = Integer.toString（Y）;
         // System.out.print（Y1 +）;
           反向= Y1 ++逆转;
         }
        的System.out.println（反向顺序：+反向）;
 

Hey so I'm taking my first cs course ever at my university its taught in java. I'm having trouble converting decimal to binary. I seem to be able to get the correct output but its in reverse order, and I have no idea how to put it in the correct order, here is what I've coded so far,

import java.util.*;
public class lab6 {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
   System.out.print("Enter a decimal number to convert to binary: ");
   int x = input.nextInt();
   int y;
   String y1="";
   while(x!=0){
       y=x%2;
       x=x/2;
       y1 = Integer.toString(y);
       System.out.print(y1+" ");
     }    
}
}

解决方案

It seems you are showing the output in correct order only. But if you want to reverse the current output you can use below code:

        Scanner input = new Scanner(System.in);
        System.out.print("Enter a decimal number to convert to binary: ");
        int x = input.nextInt();
        int y;
        String y1="";
        String reverse = "";
        while(x!=0){
           y=x%2;
           x=x/2;
           y1 = Integer.toString(y);
         //  System.out.print(y1+" ");
           reverse = y1+" "+reverse;
         }          
        System.out.println("Reverse Order :"+reverse);
