The first integer value is the index position where the extraction will start, and the second integer value is the length of the substring. 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.. Strings are used for storing text. Begin the extraction at position 2, and extract the rest of the string: If "start" is greater than "end", it will swap the two arguments: If "start" is less than 0, it will start extraction from index We pass begin index and end index number position in the java substring method where start index is inclusive and end index is exclusive. Tip: To extract characters from the end of the string, use a negative start number (This does not work in IE 8 and earlier). The substring begins at the specified beginIndex and extends to the character at index endIndex - 1. Take breaks when needed, and go over the examples as many times as needed. Syntax.
