【Java】字符串转为十六进制

作者:akang / 发布于2015/10/19/ 911


	public static void demoChangeStringToHex(final String inputString) {
	 int changeLine = 1;
	 String s = "Convert a string to HEX/こんにちは/你好";
	 if (inputString != null) {
	 s = inputString;
	 }
	 System.out.println(s);
	 for (int i = 0; i < s.length(); i++) {
	 byte[] ba = s.substring(i, i + 1).getBytes();
	 // & 0xFF for preventing minus
	 String tmpHex = Integer.toHexString(ba[0] & 0xFF);
	 System.out.print("0x" + tmpHex.toUpperCase());
	 System.out.print(" ");
	 if (changeLine++ % 8 == 0) {
	 System.out.println("");
	 }
	 // Multiply byte according
	 if (ba.length == 2) {
	 tmpHex = Integer.toHexString(ba[1] & 0xff);
	 System.out.print("0x" + tmpHex.toUpperCase());
	 System.out.print(" ");
	 if (changeLine++ % 8 == 0) {
	 System.out.println("");
	 }
	 }
	 }
	
	 System.out.println(""); // change line
	 System.out.println(""); // change line
	}

试试其它关键字

　十六进制　

同语言下

可能有用的
