java 十六进制数字转换为十六进制的字符串问题？

[tech_leopard]

大家好，请教个问题，我从单片机读取到一段数字，比如：byte []dataBuf={0xaa,0xbb,0xcc,0x08}; 我想转换成字符串String strBuf = "aa bb cc 08"; 请问该如何操作?

	private final static byte[] hex = "0123456789ABCDEF".getBytes();  
	  
	private static int parse(char c) {  
	    if (c >= 'a')  
	        return (c - 'a' + 10) & 0x0f;  
	    if (c >= 'A')  
	        return (c - 'A' + 10) & 0x0f;  
	    return (c - '0') & 0x0f;  
	}  
	// 从字节数组到十六进制字符串转换  
	public static String Bytes2HexString(byte[] b) {  
	    byte[] buff = new byte[2 * b.length];  
	    for (int i = 0; i < b.length; i++) {  
	        buff[2 * i] = hex[(b[i] >> 4) & 0x0f];  
	        buff[2 * i + 1] = hex[b[i] & 0x0f];  
	    }  
	    return new String(buff);  
	}  
	  
	// 从十六进制字符串到字节数组转换  
	public static byte[] HexString2Bytes(String hexstr) {  
	    byte[] b = new byte[hexstr.length() / 2];  
	    int j = 0;  
	    for (int i = 0; i < b.length; i++) {  
	        char c0 = hexstr.charAt(j++);  
	        char c1 = hexstr.charAt(j++);  
	        b[i] = (byte) ((parse(c0) << 4) | parse(c1));  
	    }  
	    return b;  
	}
