Java StringBuilder lastIndexOf() Method Example

Java StringBuilder lastIndexOf() method has 2 overloaded versions. Here are all of its forms:
  1. int lastIndexOf(String str) - Returns the index within this string of the rightmost occurrence of the specified substring.
  2. int lastIndexOf(String str, int fromIndex) - Returns the index within this string of the last occurrence of the specified substring.

Java StringBuilder lastIndexOf() Method Example

This example demonstrates the usage of 2 lastIndexOf() overloaded methods.
public class LastIndexOfExample { public static void main(String[] args) { StringBuilder builder = new StringBuilder("javaguides"); // method1 int lastIndexOf = builder.lastIndexOf("guides"); System.out.println(" last index of given string 'guides' in' " + builder.toString() + "' :: " + lastIndexOf); // method 2 lastIndexOf = builder.lastIndexOf("java", 3); System.out.println(" last index of given string 'java' in' " + builder.toString() + "' :: " + lastIndexOf); } }
Output:
 last index of given string 'guides' in' javaguides' :: 4 last index of given string 'java' in' javaguides' :: 0
