In this section, you will get the detailed explanation about the lastIndexOf(String str) method of String class. We are going to use lastIndexOf(String str) method of String class in Java. The description of the code is given below for the usage of the method.

Description of the code:

Here, you will get to know about the
lastIndexOf(String str) method through the following java program. In the program code given below, we have taken a String. To find the last index of a Substring from the String, we have applied lastIndexOf(String str); method and then we have passed the Substring in that to find its last index as shown in the output.

NOTE: This method returns the index of the rightmost occurrence of the given substring within the string.

Here is the code of program:

public class LastIndxOfStr {
  public static void main(String args[]) {
  String s = "Honesty is the best Policy";
  System.out.println(s);
  System.out.println("lastIndexOf(the) -> " + s.lastIndexOf("nest"));
  }
  }

Output of the program:

C:\unique>javac LastIndxOfStr.java

C:\unique>java LastIndxOfStr
Honesty is the best Policy
lastIndexOf(the) -> 2

C:\unique>

I don't understand the example

In the example you have shown lastIndexOf('the') in the output message. But in the actual method you have taken the substring as 'nest'. In the Output the index is shown as 2. Can you please explain how did u get the output and also for which sub string is that output meant to be.
