What is StringUtils.right() in Java?
Overview
right() is a StringUtils class that is used to get the rightmost characters of a string.
How to import StringUtils
The definition of StringUtils can be found in the Apache Commons Lang package, which we can add to the Maven project by adding the following dependency to the pom.xml file.
<dependency>
<groupId>org.apache.commons</groupId>
<artifactId>commons-lang3</artifactId>
<version>3.12.0</version>
</dependency>
For other versions of the
commons-langpackage, refer to the Maven Repository.
You can import the StringUtils class as follows.
import org.apache.commons.lang3.StringUtils;
Syntax
public static String right(final String str, final int len)
Parameters
final String str: The string to get the rightmost characters from.final int len: The length of the rightmost characters to extract from the string.
Return value
This method returns the rightmost characters of the string.
Code
The code below shows how the right() method works in Java.
import org.apache.commons.lang3.StringUtils;public class Main{public static void main(String[] args) {// Example 1String string = "hello-educative";int len = 5;System.out.printf("StringUtils.right('%s', %s) = '%s'", string, len, StringUtils.right(string, len));System.out.println();// Example 2len = -1;System.out.printf("StringUtils.right('%s', %s) = '%s'", string, len, StringUtils.right(string, len));System.out.println();}}
Output
The output of the code will be as follows:
StringUtils.right('hello-educative', 5) = 'ative'
StringUtils.right('hello-educative', -1) = ''
Explanation
Example 1
string = "hello-educative"length = 5
The method returns ative which is the rightmost substring of the given string with length 5.
Example 2
string = "hello-educative"length = -1
The method returns ``, an empty string, as the length value is negative.
