我只写到了将任意十进制转换成二进制- -
求大神指点指点
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.util.Scanner;
public class Conversation {
public static void main(String args[]){
Scanner input = new Scanner(System.in);
System.out.print("请输入二进制数字: ");
int m=input.nextInt();
toBinary(m);
}
static void toBinary(int num){
if(num/2==0){
int w = num%2;
System.out.print(w+" ");
}
else{
int w = num%2;
toBinary(num/2);
System.out.print(w+" ");
}
}
}
额，这是把二进制转换成十进制的....
package com.rui.test;
public class test {
public static void main(String[] args) {
//定义一个二进制的数
String str="1010";
//将这个二进制的字符串进行反串
char [] ch=str.toCharArray();
for (int i = 0; i < ch.length; i++) {
char c=ch[i];
ch[i]=ch[ch.length-i- 1];
ch[ch.length-i-1]=c;
if ((ch.length-1)/2 ==i) {
break;
}
}
StringBuffer strbuff=new StringBuffer(String.copyValueOf(ch));
int num=0;
for (int i = 0; i < strbuff.length(); i++) {
num+=(strbuff.charAt(i)-48)*Math.pow(2,i);
}
System.out.println(num);
}
}
