String lastIndexOf(int ch)

     

In this section, you will get the detailed explanation about the lastIndexOf(int ch) method of String class. We are going to use lastIndexOf(int ch) 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(int ch) method through the following java program. In the program code given below, we have taken a String. To find the last index of any character in a string we have applied lastIndexOf(int ch); method and then we have passed a character from the string in that to find its last index as shown in the output. You must be observing in the output that we have also taken the ASCII value of small "b" which is 98.  Hence its also giving the same result.

NOTE: This method returns the index of the last occurrence of the given character within the string.

Here is the code of the program:

public class LastIndexOfCh {
  public static void main(String args[]) {
  String s = "Honesty is the best Policy";
  System.out.println(s);
  System.out.println("lastIndexOf(b) -> " + s.lastIndexOf(98));
  System.out.println("lastIndexOf(b) -> " + s.lastIndexOf('b'));
  }
  }

Output of the program:

C:\unique>javac LastIndexOfCh.java

C:\unique>java LastIndexOfCh
Honesty is the best Policy
lastIndexOf(b) -> 15
lastIndexOf(b) -> 15
