#SUBSTRING JAVA CHARACTER CODE#

The substring begins at the specified beginIndex and extends to the character at index endIndex - 1. Returns a new string that is a substring of this string. The integer argument specifies the index of the first character.

Here are several other String methods for manipulating strings: Other Methods in the String Class for Manipulating Strings Method String roar = anotherPalindrome.substring(11, 15) The following code gets from the Niagara palindrome the substring that extends from index 11 up to, but not including, index 15, which is the word 'roar': Here, the returned substring extends to the end of the original string. Searches for a match as specified by the string argument (which contains a regular expression) and splits this string into an array of strings accordingly. Regular expressions are covered in the lesson titled 'Regular Expressions.'ĬharSequence subSequence(int beginIndex, int endIndex) The optional integer argument specifies the maximum size of the returned array. Returns a new character sequence constructed from beginIndex index up until endIndex - 1. Returns a copy of this string with leading and trailing white space removed. Returns a copy of this string converted to lowercase or uppercase. Searching for Characters and Substrings in a String If no conversions are necessary, these methods return the original string. Here are some other String methods for finding characters or substrings within a string. The String class provides accessor methods that return the position within the string of a specific character or substring: indexOf() and lastIndexOf(). The indexOf() methods search forward from the beginning of the string, and the lastIndexOf() methods search backward from the end of the string. If a character or substring is not found, indexOf() and lastIndexOf() return -1.

The String class also provides a search method, contains, that returns true if the string contains a particular character sequence.
