java,漢字轉unicode碼|unicode轉漢字

一、java,漢字轉unicode碼|unicode轉漢字:

public class UnicodeStr {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		System.out.println(str2Unicode("最真不過平淡,最美不過平凡。"));
		System.out.println(unicode2Str("\u6700\u771f\u4e0d\u8fc7\u5e73\u6de1\uff0c\u6700\u7f8e\u4e0d\u8fc7\u5e73\u51e1\u3002"));
	}

	 public static String str2Unicode(String s)
	  {
	    String str = "";
	    if ((s == null) || (s.trim().equals("")))
	      return str;
	    for (int i = 0; i < s.length(); i++)
	    {
	      byte[] bytes = String.valueOf(s.charAt(i)).getBytes();
	      String s4;
	      if (bytes.length == 1)
	      {
	        s4 = String.valueOf(s.charAt(i));
	      } else {
	        int ch = s.charAt(i);
	        s4 = "\\u" + Integer.toHexString(ch);
	      }
	      str = str + s4;
	    }
	    return str;
	  }

	 public static String unicode2Str(String theString) {
		  char aChar;
		  int len = theString.length();
		  StringBuffer outBuffer = new StringBuffer(len);
		  for (int x = 0; x < len;) {
		   aChar = theString.charAt(x++);
		   if (aChar == '\\') {
		    aChar = theString.charAt(x++);
		    if (aChar == 'u') {
		     int value = 0;
		     for (int i = 0; i < 4; i++) {
		      aChar = theString.charAt(x++);
		      switch (aChar) {
		      case '0':
		      case '1':
		      case '2':
		      case '3':
		      case '4':
		      case '5':
		      case '6':
		      case '7':
		      case '8':
		      case '9':
		       value = (value << 4) + aChar - '0';
		       break;
		      case 'a':
		      case 'b':
		      case 'c':
		      case 'd':
		      case 'e':
		      case 'f':
		       value = (value << 4) + 10 + aChar - 'a';
		       break;
		      case 'A':
		      case 'B':
		      case 'C':
		      case 'D':
		      case 'E':
		      case 'F':
		       value = (value << 4) + 10 + aChar - 'A';
		       break;
		      default:
		       throw new IllegalArgumentException(
		         "Malformed      encoding.");
		      }

		     }
		     outBuffer.append((char) value);
		    } else {
		     if (aChar == 't') {
		      aChar = '\t';
		     } else if (aChar == 'r') {
		      aChar = '\r';
		     } else if (aChar == 'n') {
		      aChar = '\n';
		     } else if (aChar == 'f') {
		      aChar = '\f';
		     }
		     outBuffer.append(aChar);
		    }
		   } else {
		    outBuffer.append(aChar);
		   }

		  }
		  return outBuffer.toString();

		 }

}

二、還有一種文字轉unicode方法就是安裝了java的jdk後就可以用bin目錄下的native2ascii.exe來轉換。先將要轉換的文字寫入一個文本文件,如str.txt ,則在命令行方式下鍵入命令:native2ascii str.txt (這個網上看到的,未測試)
