Java字符串跟ASCII码互转详解编程语言

1.由于项目中遇到，在服务器端起的jar包程序，给前台发消息后，前段收到的消息出现乱码情况，所以采取在后才发消息前先把消息字符串转成ASCII码再发往前台，前台采取在收到后台消息先把ASCII码转成字符串的解决方案进行解决。

 1）将字符串转成ASCII的Java方法

public static String stringToAscii(String value) 

 StringBuffer sbu = new StringBuffer(); 

 char[] chars = value.toCharArray(); 

 for (int i = 0; i chars.length; i++) { 

 if(i != chars.length - 1) 

 sbu.append((int)chars[i]).append(","); 

 else { 

 sbu.append((int)chars[i]); 

 return sbu.toString(); 

} 

2）将ASCII转成字符串的java方法

public static String asciiToString(String value) 

 StringBuffer sbu = new StringBuffer(); 

 String[] chars = value.split(","); 

 for (int i = 0; i chars.length; i++) { 

 sbu.append((char) Integer.parseInt(chars[i])); 

 return sbu.toString(); 

} 

main方法测试：

public static void main(String[] args) { 

 String str = "{name:1234,password:4444}"; 

 String asciiResult = stringToAscii(str); 

 System.out.println(asciiResult); 

 String stringResult = asciiToString(asciiResult); 

 System.out.println(stringResult); 

 

输出：

123,110,97,109,101,58,49,50,51,52,44,112,97,115,115,119,111,114,100,58,52,52,52,52,125 

{name:1234,password:4444}
