lastindexOf() in Java strings ?

 lastindexOf() in java strings ?

>> In Java, lastindexOf() method is available in String class.

>> lastindexOf() method is used to retrieve the index of a given character or substring.

>> If it is not found it will return -1.

Java program using lastindexOf():

Lets say we have given input string:

lastIndexOf()

public class lastIndex {

    public static void main(String[] args) {
    String s = "This is example string";

    // lastIndexOf("String")
    System.out.println("Position of x=" + s.lastIndexOf("x"));
    System.out.println("Position of string=" + s.lastIndexOf("xample"));
    System.out.println("if searched string not present=" + s.lastIndexOf("adsa"));

    // lastIndexOf('character')
    System.out.println("Position of character=" + s.lastIndexOf('i'));

    // lastIndexOf("string","fromIndex")
    System.out.println("Position of searched string from specified index=" + s.lastIndexOf("e", 9));

    // lastIndexOf('character',"fromIndex")
    System.out.println("Position of searched character from specified index=" + s.lastIndexOf('i', 6));

    System.out.println("if searched substring not occur=" + s.lastIndexOf("a", 20));
  }
}

Output:
lastindexOf() java
As mentioned in above program we have 4 types lastindexOf() methods:
int lastindexOf(String substring) - returns the last index of given substring
int lastindexOf(int ch) - returns the last index of given character value
int lastindexOf(string substring,int fromindex) - returns last index position for the given substring and from index(before the index)
int lastindexOf(int ch,int fromindex) - returns index position for the given char value and from index(before the index)
