Java字符串转成二进制码的方法

public void toBinary(){  String str = "王雪";  char[] strChar=str.toCharArray();  String result="";  for(int i=0;i<strChar.length;i++){    result +=Integer.toBinaryString(strChar[i])+ " ";  }  System.out.println(result);}

//将二进制字符串转换成int数组  public 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;  }    //将二进制转换成字符   public char BinstrToChar(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;  }  public void BinstrToStr(){    String binStr = "111001110001011 1001011011101010 ";    String[] tempStr=binStr.split(" ");    char[] tempChar=new char[tempStr.length];    for(int i=0;i<tempStr.length;i++) {      tempChar[i]=BinstrToChar(tempStr[i]);    }    System.out.println(String.valueOf(tempChar));   }
