Comparison is case insensitive. Right pad a String with a specified String. Note that the method does not allow for a leading sign, either positive or negative. Centers a String in a larger String of size size. A null String will return -1. Returns padding using the specified delimiter repeated but a search array containing "" will return the length of str Converts a String to upper case as per String.toUpperCase(Locale). Removes control characters (char <= 32) from both Two null This means that null will return false. A null array entry will be ignored. separators specified, preserving all tokens, including empty tokens So a tab becomes the characters '\\' and An empty String (length()=0) always returns true. Checks if the String contains only whitespace. Gets the rightmost len characters of a String. The symbol * is used to indicate any input including null. Two null Locale.ENGLISH).

Note: The code starts looking for a match at the start of the target, For example, replaceChars("hello", "ho", "jy") = jelly. Centers a String in a larger String of size size. Finds the first index within a CharSequence, handling null. A null source string will return null. A null invalid character array will return true. DOTALL is also known as single-line mode in Perl.

Find the Fuzzy Distance which indicates the similarity score between two Strings. The difference is that Java's whitespace includes vertical tab and form feed, which this functional will also In no case will it return a String of length greater than maxWidth. the source string. This method uses String.indexOf(int) if possible. A negative start position is treated as zero. Checks if the String contains only lowercase characters. This abbreviation only occurs if the following criteria is met: Otherwise, the returned String will be the same as the supplied String for abbreviation. A null CharSequence will return -1. characters that is common to all of them. Operations on String that are preserving all tokens, including empty tokens created by adjacent Java example source code file (StringUtils.java) This example Java source code file (StringUtils.java) is included in the alvinalexander.com "Java Source Code Warehouse" project.The intent of this project is to help you "Learn Java by Example" TM.Learn more about this Java project at its project page.
