在Java中,你可以通过new String(byte[] bytes, String charsetName)构造函数来创建一个新的String对象,并指定字节数组和相应的编码格式。这种方式非常实用,尤其是在从网络或文件中读取字节流的时候。 代码示例 以下是一个基本示例,展示如何从字节数组创建字符串,并指定编码格式: importjava.nio.charset.StandardCharsets...
string.getBytes("charset"):将string中的字符数组按照我们指定charset格式转成字节数组。 new String(byte[] byteArray, "charset"):告诉java说,字节数组byteArray是按照charset格式解码得来的,现在需要对它进行解析并转化成内码为Utf-16格式的字符。因此,使用这个方法,要先确定好字节数组byteArray是按照什么编码格式得...

jsp ___byte[] bytes = stemp.getBytes("ISO-8859-1");1.String name=request.getParameter("putInName"); 2.String n=request.getParameter("putInNumber"); 3.byte[] b=name.getBytes("ISO-8859-1"); 4.name=new String(b,“gb2312”); 3行和4行什么意思? 为什么要执行第三行(直接name不行?)?
properly, and it comes with full support for all commonUnicodeaware charsets such as UTF-8, UTF-16, UTF-16BE, UTF-16LE, UTF-32, UTF-32LE, UTF-32BE, and GB18030. AByte-Order Mark (BOM)is supported for both input and output, even if a BOM is optional for the selected charset....
