java 转码

java 转码很简单。
［1］要搞清楚转面源的编码，保证读取进来的字符串是正确的。

   BufferedReader in = new BufferedReader(new InputStreamReader(
				new FileInputStream(f), "GB2312"));

［2］字符串被正确读取后，保存在java中的就是unicode字符集的序列码了。
［3］gbrs.getBytes("UTF-8") 写入目标编码。这一步其实就已经正确的编码了。返回的数组就是编好码的数组

	public static void printBytes(byte[] bytes){
		for (int i = 0; i < bytes.length; i++) {
			int j = (int) bytes[i];
			System.out.println("coding: ------------------"
					+ Integer.toHexString(j));
		}
		
	System.out.println();
				
	}

  		printBytes(gbrs.getBytes("GB2312"));
		
		printBytes(gbrs.getBytes("UTF-8"))

［4］最后用真确的编码转换成字符串

		
		   System.out.println(Charset.availableCharsets());

		File f = new File("/home/linwei007/temp/aa");

		BufferedReader in = new BufferedReader(new InputStreamReader(
				new FileInputStream(f), "GB2312"));
		String gbrs = in.readLine();
		System.out.println(gbrs);
		
		printBytes(gbrs.getBytes("GB2312"));
		
		printBytes(gbrs.getBytes("UTF-8"));

	    System.out.println(new String(gbrs.getBytes("UTF-8"),"UTF-8"));
