Java二进制与任意字符转换源代码

Java二进制与任意字符转换源代码

源代码如下:

public class StrBinaryTurn {
     //将字符串转换成二进制字符串，以空格相隔
     public String toBinary(String str){
         char[] strChar = str.toCharArray();
         String result = "";
         for(int i = 0; i < strChar.length; i++){
           
             result += Integer.toBinaryString(strChar[i]) + " ";
         }
         return result;
       
     }
     //将二进制字符串转换成Unicode字符串
     public String toStr(String binStr){
         String[] tempStr = StrToStrArray(binStr);
         char[] tempChar = new char[tempStr.length];
         for(int i = 0; i < tempStr.length; i++){
             tempChar[i] = toChar(tempStr[i]);
         }
         return String.valueOf(tempChar);
     }
     //将二进制字符串转换为char
     private char toChar(String binStr){
         int[] temp = binStrToIntArray(binStr);
         int sum = 0;
       
         for(int i = 0; i < temp.length; i++){

             sum += temp[temp.length - 1 - i] << i;

         }
   
         return (char)sum;
       
     }
     //将初始二进制字符串转换成字符串数组，以空格相隔
     private String[] StrToStrArray(String str){
         return str.split(" ");
     }
   

     //将二进制字符串转换成int数组
     private int[] binStrToIntArray(String binStr){
       
         char[] temp = binStr.toCharArray();
         int[] result = new int[temp.length];
   
         for(int i = 0; i < temp.length; i++){
             result[i] = temp[i] - 48;
         }
         return result;
       
     }
   
     public static void main(String[] args){
       
         StrBinaryTurn cTob = new StrBinaryTurn();
         System.out.println(cTob.toBinary("橘子，好吃！aaa"));
         System.out.println();
         System.out.println(cTob.toBinary("999111"));
         System.out.println();
         System.out.println(cTob.toBinary("What a nice day!"));
         System.out.println();
         System.out.println(cTob.toBinary("^@^ - -! （）★"));
       
         System.out.println();
         System.out.println();
       
         System.out.println(cTob.toStr("110101001011000 101101101010000 " +
                 "1111111100001100 101100101111101 " +
                 "101010000000011 1111111100000001 " +
                 "1100001 1100001 1100001 "));
         System.out.println(cTob.toStr("111001 111001 111001 " +
                 "110001 110001 110001"));
         System.out.println(cTob.toStr("1010111 1101000 1100001 " +
                 "1110100 100000 1100001 100000 1101110 " +
                 "1101001 1100011 1100101 100000 1100100 " +
                 "1100001 1111001 100001 "));
         System.out.println(cTob.toStr("1011110 1000000 1011110 " +
                 "100000 101101 100000 101101 100001 100000 " +
                 "1111111100001000 1111111100001001 10011000000101 "));
     }
}

输出结果:
