1 new String();//创建一个空的字符串对象 2 new String(byte[] bytes);//通过使用平台的默认字符编码指定的 byte 数组创建字符串对象 3 new String(byte[] bytes,Charset charset);//通过使用指定编码指定的byte数组创建字符串对象 4 new String(byte[] bytes,int offset, int length); 5 new String(by...
最后通过array()方法获取到真正的字节数组gbkBytes。 完整代码 下面是将字符串转为GBK字节的完整代码: importjava.nio.ByteBuffer;importjava.nio.CharBuffer;importjava.nio.charset.Charset;publicclassStringToGBKBytesExample{publicstaticvoidmain(String[]args){Stringstr="Hello, 你好!";byte[]bytes=str.getBytes()...
String str1 =newString(bytes,"UTF-8");//to UTF-8 string String str2 =newString(bytes,"ISO-8859-1");//to ISO-8859-1 string String str3 =newString(bytes,"GBK");//to GBK string System.out.println(str1);//abc你好 System.out.println(str2);//abc??? System.out.println(str3);/...

使用String类的getBytes()方法将字符串转换为字节数组,再使用新的字符集构造一个新的字符串: String str = "Hello, 你好"; byte[] bytes = str.getBytes("UTF-8"); String newStr = new String(bytes, "GBK"); System.out.println(newStr); 复制代码 使用InputStreamReader和OutputStreamWriter类来进行字...

unicodeToUtf8 (String s) { return new String( s.getBytes("utf-8") , "utf-8"); } UTF-8 转GBK原理也是一样 return new String( s.getBytes("GBK") , "GBK"); 其实核心工作都由 getBytes(charset) 做了。 getBytes 的JDK 描述:Encodes this String into a sequence of bytes using the named...
此时b_gbk的长度为2,b_utf8的长度为3,b_iso88591的长度为1。 public String(byte[] bytes, Charset charset) Constructs a new String by decoding the specified array of bytes using the specified charset. The length of the new String is a function of the charset, and hence may not be equal ...
new String(byte[], charsetName) Constructs a new String by decoding the specified array of bytes using the specified charset. The length of the new String is a function of the charset, and hence may not be equal to the length of the byte array....
