输入一个十进制整数并将其转化为二进制整数输出

package com.rya.three;

import java.util.Scanner;

public class TenToTwo {
    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        System.out.print("请输入一个数：");
        int n = in.nextInt();
        int t = 0;//记录位数
        int r = 0;//存储余数
        int bin = 0;//存储最后二进制数
        while (n != 0) {
            r = n % 2;
            n = n / 2;
            bin += (int) (r * Math.pow(10, t));
            t++;
        }
        System.out.println("对应的二进制为：" + bin);
    }
