Substring java code#

Let's understand the startIndex and endIndex by the code given below. 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. Case mapping is based on the Unicode Standard version specified by the Character class. This method returns new String object containing the substring of the given string from specified startIndex to endIndex. The class String includes methods for examining individual characters of the sequence, for comparing strings, for searching strings, for extracting substrings, and for creating a copy of a string with all characters translated to uppercase or to lowercase. 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. This method returns new String object containing the substring of the given string from specified startIndex (inclusive). public String substring(int startIndex):.You can get substring from the given String object by one of the two methods:

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. Example 1: Let us consider the string bat. Substring: A String that is a part of another string is called substring of the other string. 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. (a) '' is a String in java with 0 character (b) 'd' is a String in java with 1 character (c) 'This is a sentence.' is a string with 19 characters. In other words, substring is a subset of another String.
