java实现十六进制字符unicode与中英文转换示例

关于unicode和utf的关系，可以简单的记忆：Unicode是一个编码组织、一个编码规范、在java中指utf-16；utf是Unicode编码的translation转换格式，以便于很好地在网络中传递、在存储媒介汇总保存，于是utf存在多种格式，如8、16、32，而关联le、te的区别，Unicode编码格式才会有以下过程中的10种。

复制代码代码如下:

public static void main(String[] args) throws UnsupportedEncodingException {
StringUtil.str2all("0 产品型号描述");
StringUtil.str4all("30000900A74EC1548B57F753CF63F08F");
}

/**
* 尝试所有编码格式对十六进制数字字符串进行编码
*
* @param hexStr
* @throws UnsupportedEncodingException
*/
public static void str4all(String uStr) throws UnsupportedEncodingException{

  System.out.println("+++++++++++++++++++++++++++++++++++++++++++++++++++");

  byte[] bs = new byte[uStr.length()/2];
  for (int i = 0; i < bs.length; i++) {
   bs[i] = (byte) Integer.parseInt(uStr.substring(i*2, i*2+2), 16);
  }

  System.out.println(new String(bs, "utf-8"));
  // 16
  System.out.println(new String(bs, "utf-16")); // 同unicode
  System.out.println(new String(bs, "utf-16le"));
  System.out.println(new String(bs, "x-utf-16le-bom"));
  System.out.println(new String(bs, "utf-16be"));
//  System.out.println(new String(bs, "x-utf-16be-bom")); // UnsupportedEncodingException
  // 32
  System.out.println(new String(bs, "utf-32"));
  System.out.println(new String(bs, "utf-32le"));
  System.out.println(new String(bs, "x-utf-32le-bom"));
  System.out.println(new String(bs, "utf-32be"));
  System.out.println(new String(bs, "x-utf-32le-bom"));
}
/**
* 列出所有编码对应的解码后的十六进制数字字符串
*
* @param uStr
* @throws UnsupportedEncodingException
*/
public static void str2all(String uStr) throws UnsupportedEncodingException{

  System.out.println("+++++++++++++++++++++++++++++++++++++++++++++++++++");

  byte[] bs = new byte[]{};

  bs = uStr.getBytes("utf-8");
  for(byte b:bs){
   System.out.print(Integer.toHexString(b & 0xff));
  }
  System.out.println();
  // 16
  bs = uStr.getBytes("utf-16");
  for(byte b:bs){
   System.out.print(Integer.toHexString(b & 0xff));
  }
  System.out.println();
  bs = uStr.getBytes("utf-16le");
  for(byte b:bs){
   System.out.print(Integer.toHexString(b & 0xff));
  }
  System.out.println();
  bs = uStr.getBytes("x-utf-16le-bom");
  for(byte b:bs){
   System.out.print(Integer.toHexString(b & 0xff));
  }
  System.out.println();
  bs = uStr.getBytes("utf-16be");
  for(byte b:bs){
   System.out.print(Integer.toHexString(b & 0xff));
  }
  System.out.println();
//  bs = uStr.getBytes("x-utf-16be-bom"); // UnsupportedEncodingException
  // 32
  bs = uStr.getBytes("utf-32");
  for(byte b:bs){
   System.out.print(Integer.toHexString(b & 0xff));
  }
  System.out.println();
  bs = uStr.getBytes("utf-32le");
  for(byte b:bs){
   System.out.print(Integer.toHexString(b & 0xff));
  }
  System.out.println();
  bs = uStr.getBytes("x-utf-32le-bom");
  for(byte b:bs){
   System.out.print(Integer.toHexString(b & 0xff));
  }
  System.out.println();
  bs = uStr.getBytes("utf-32be");
  for(byte b:bs){
   System.out.print(Integer.toHexString(b & 0xff));
  }
  System.out.println();
  bs = uStr.getBytes("x-utf-32le-bom");
  for(byte b:bs){
   System.out.print(Integer.toHexString(b & 0xff));
  }
  System.out.println();
}
