The value of where must be nonnegative and specify a location within the string. Here, where is the index of the character that you want to obtain. To extract a single character from a String, the charAt( ) method is used. To obtain this value, the length( ) method is used to find length of a string. The length of a string is the number of characters that it contains. The constructor can have a String object that contains the same character sequence as another String object using following constructor: Here, startIndex specifies the index at which the subrange begins, and numChars specifies the number of characters to use. String(char chars, int startIndex, int numChars ) It is possible to specify a subrange of a character array as an initializer using the following constructor: Here, the constructor has the char array as an argument. 
To create a String initialized by an array of characters, use the constructor shown here: The String class provides a variety of constructors to handle this. Here, it will create an instance of String with no characters in it. To create an empty String, call the default constructor.
