Java String lastIndexOf() Sample Code


Description:

Below example shows how to get index of a given character or string from a string in the reverse order, means last occuring index. By using lastIndexOf() method you can get last occurence of the the reference string or character. Also lastIndexOf() method gives last occurence based on a specific position.


Code:
package com.myjava.string;

public class MyStrLastIndexOf {

    public static void main(String a[]){
    
        String str = "Use this string for testing this";
        System.out.println("Basic lastIndexOf() example");
        System.out.println("Char 's' at last occurance: "+str.lastIndexOf('s'));
        System.out.println("String \"this\" at last occurance: "+str.lastIndexOf("this"));
        /**
         * Returns the last occurance from specified start index, 
         * searching backward starting at the specified index.
         */
        System.out.println("first occurance of char 's' from 24th index backwards: "
							+str.lastIndexOf('s',24));
        System.out.println("First occurance of String \"this\" from 26th index backwards: "
							+str.lastIndexOf("this",26));
    }
}

Example Output

Basic lastIndexOf() example
Char 's' at last occurance: 31
String "this" at last occurance: 28
first occurance of char 's' from 24th index backwards: 22
First occurance of String "this" from 26th index backwards: 4

Stream and types of Streams
A Stream is an abstraction that either produces or consumes information. There are two types of Streams and they are:

Byte Streams: Provide a convenient means for handling input and output of bytes. Byte Streams classes are defined by using two abstract classes, namely InputStream and OutputStream.

Character Streams: Provide a convenient means for handling input & output of characters. Character Streams classes are defined by using two abstract classes, namely Reader and Writer.
