java实现输入一个任意十进制数转换为二进制数

package com.xingyi.one.firstdemo;

import java.util.Scanner;

public class FirstDemo {

//将任意一个十进制数转换为二进制数

public void NumberChanger() {

Scanner sc = new Scanner(System.in);

System.out.println("Please input number");

int number = sc.nextInt();

System.out.println("该数字转换后的二进制数字是：");

int sum;

String result = "";

for(int i=number; i>=1; i=i/2) {

if(i%2==0) {

sum = 0;

}else {

sum = 1;

}

result = sum+result;

}

System.out.println(result);

}

public static void main(String[] args) {

FirstDemo fo = new FirstDemo();

fo.NumberChanger();

}
