public String (byte[] bytes, int offset, int length)

Constructs a new String by decoding the specified subarray of bytes using the platform's default charset. The length of the new String is a function of the charset, and hence may not be equal to the length of the subarray.

The behavior of this constructor when the given bytes are not valid in the default charset is unspecified. The java.nio.charset.CharsetDecoder class should be used when more control over the decoding process is required.

Parameters:
bytes     The bytes to be decoded into characters
offset     The index of the first byte to decode
length     The number of bytes to decode

Exceptions:
IndexOutOfBoundsException     If the offset and the length arguments index characters outside the bounds of the bytes array
