Field Summary
FieldsModifier and TypeFieldDescription static Comparator CASE_INSENSITIVE_ORDERA Comparator that orders String objects as by compareToIgnoreCase.
Constructor Summary
ConstructorsConstructorDescription String[] Initializes a newly created String object so that it represents an empty character sequence.
String[byte[] bytes] Constructs a new String by decoding the specified array of bytes using the platform's default charset.
String[byte[] ascii, int hibyte] Deprecated.
This method does not properly convert bytes into characters.
String[byte[] bytes, int offset, int length] Constructs a new String by decoding the specified subarray of bytes using the platform's default charset.
String[byte[] ascii, int hibyte, int offset, int count] Deprecated.
This method does not properly convert bytes into characters.
String[byte[] bytes, int offset, int length, String charsetName] Constructs a new String by decoding the specified subarray of bytes using the specified charset.
String[byte[] bytes, int offset, int length, Charset charset] Constructs a new String by decoding the specified subarray of bytes using the specified charset.
String[byte[] bytes, String charsetName] Constructs a new String by decoding the specified array of bytes using the specified charset.
String[byte[] bytes, Charset charset] Constructs a new String by decoding the specified array of bytes using the specified charset.
String[char[] value] Allocates a new String so that it represents the sequence of characters currently contained in the character array argument.
String[char[] value, int offset, int count] Allocates a new String that contains characters from a subarray of the character array argument.
String[int[] codePoints, int offset, int count] Allocates a new String that contains characters from a subarray of the Unicode code point array argument.
String[String original] Initializes a newly created String object so that it represents the same sequence of characters as the argument; in other words, the newly created string is a copy of the argument string.
String[StringBuffer buffer] Allocates a new string that contains the sequence of characters currently contained in the string buffer argument.
String[StringBuilder builder] Allocates a new string that contains the sequence of characters currently contained in the string builder argument.
