String lastIndexOf(int ch, int fromIndex)

In this section, you will get the detailed explanation about the lastindexOf(int ch, int fromIndex) method of String class. We are going to use lastindexOf(int ch, int fromIndex) 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, int fromIndex) method through the following java program. In the program code given below, we have taken a String. To find the last index of a character from the specified string, we have applied lastindexOf(int ch, int fromIndex) method and then we have passed the character with the index number to that to find its index as shown in the output. We have also taken the ASCII value of the character in the example below which also gives the same output.

NOTE: This method returns the index of the last occurrence of the given character, searching backward starting at the specified index within the string .

Here is the code of the program:


public class lastIndexofChar{

  public static void main(String args[]){

  String s = "Java is a wonderful language";

  System.out.println(s);

  System.out.println("lastIndexOf(a, 19) = " + s.lastIndexOf('a', 19));

  System.out.println("lastIndexOf(a, 19) = " + s.lastIndexOf(97, 19));

  }

  }

Output of the program:

C:\unique>javac lastIndexofChar.java

C:\unique>java lastIndexofChar
Java is a wonderful language
lastIndexOf(a, 19) = 8
lastIndexOf(a, 19) = 8

C:\unique>
