我们定义发送者和接收者,发送者作为客户端,接收者作为服务端。 Sender.java import java.io.DataOutputStream;import ...

能使这个算式简便,public String byte2hex(byte[] b) //二行制转字符串 { String hs=""; String stmp=""; for (int n=0;n

Byte.parseByte(s, 16)将s转换成有符号数 ,这一个字节能表示的范围是:-128~127,下面的代码是在搜来的代码基础上稍做了修改,调用的时候你只要把temperature传进去即可得到转换后的byte数组,byte数组的长度由temperature的值决定,你要求只能...

应该用byte型数组 public static String stringToHexString(String strPart) { String hexString = ""; for (int i = 0; i < strPart.length(); i++) { int ch = (int) strPart.charAt(i); String strHex = Integer.toHexString(ch); hexString ...

int x=0xFFAA1234; //这是32位 x = (int)Long.parseLong("FFAA1234",16); byte[] b = new byte[4]; b[0] = (byte)(x>>>24); b[1] = (byte)(x>>>16); b[2] = (byte)(x>>>8); b[3] = (byte)x;

nt main(void) 4{ 5 unsigned char array[4] = {"0x0","0x0","0x02","0xe7"}; 6 unsigned long num; 7 num = 0; 8 for(int i=0; i= '0') && (abt[2 * p] = 'a') && (abt[2 * p] = '0') && (abt[2 * p + 1] = 'a') && (abt[2 * p + 1] > 4); int ...

package lzh.Util; /** * * @author http://hi.baidu.com/gladfeel/blog/item/7d45b01e7be529164034176b.html*/ public class String2Hex { public static String toHexString1(byte[] b) { StringBuffer buffer = new StringBuffer(); for (int...

你自己把这个字符串打转化成二进制就可以了。

如果你需要加密我这里有一个不知道何时不: package com.palic.pss.afcs.worldthrough.common.util;import javax.crypto.Cipher;import javax.crypto.spec.SecretKeySpec;import repack.com.thoughtworks.xstream.core.util.Base64Encoder;/** *...

public class Hex2Image { public static void main(String[] args) throws Exception { Hex2Image to=new Hex2Image(); InputStream is=new FileInputStream("c:/work/today.txt"); InputStreamReader isr = new InputStreamReader(is); Buffer...
