The method throws an IndexOutOfBoundException when the startIndex is less than zero or startIndex is greater than endIndex or endIndex is greater than length of String. This method returns new String object containing the substring of the given string from specified startIndex to endIndex. public String substring(int startIndex, int endIndex):.The method throws an IndexOutOfBoundException when the startIndex is larger than the length of String or less than zero. Thus the length of the substring is endIndex-beginIndex. The substring begins at the specified beginIndex and extends to the character at index endIndex - 1. It returns a new string that is a substring of this string. This method returns new String object containing the substring of the given string from specified startIndex (inclusive). The substring (int beginIndex, int endIndex) method of the String class. ![]() public String substring(int startIndex):.You can get substring from the given String object by one of the two methods: (abc) String cde cde (abc + cde) String c abc.substring(2,3) String d cde.substring(1, 2). Suppose the string is " computer", then the substring will be com, compu, ter, etc. In case of substring() method startIndex is inclusive and endIndex is exclusive. You can write the string explicitly as an argument, like this: SELECT SUBSTRING('This is the first substring example', 9, 10) AS substringextraction This means: I want to find a substring from the text ‘This is the first substring example’. Java String class provides the built-in substring() method that extract a substring from the given string by using the index values passed as an argument. The SUBSTRING () function returns a substring from any string you want. In other words, substring is a subset of another String.
