Inserts characters in a subsequence of the specified character sequence value into this string builder at the specified index and returns this instance.
The inserted characters go in the same order as in the value character sequence, starting at index.
index - the position in this string builder to insert at.
value - the character sequence from which a subsequence is inserted.
startIndex - the beginning (inclusive) of the subsequence to insert.
endIndex - the end (exclusive) of the subsequence to insert.
IndexOutOfBoundsException - or IllegalArgumentException when startIndex or endIndex is out of range of the value character sequence indices or when
startIndex > endIndex.
IndexOutOfBoundsException - if index is less than zero or greater than the length of this string builder.
