使用byte []和charset的构造函数创建字符串对象

Question

I am creating a String object using new String(byte[], Charset) where Charset = UTF8 and byte[] is encoded into ISO-8859-1 . I have tested with normal characters and it worked. But not clear if it can create any problem.

Pleas suggest.

new String(byteArray,Charset.forName("UTF-8"));

Read the API documentation regarding the constructor. According to that you will not get any issues even if you get a corrupted byte array.

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 to the length of the byte array. This method always replaces malformed-input and unmappable-character sequences with this charset's default replacement string. The CharsetDecoder class should be used when more control over the decoding process is required
