Java String Exercises: Count the number of words ending in 'm' or 'n' (not case sensitive) in a given text

Java String: Exercise-91 with Solution

Write a Java program to count the number of words ending in 'm' or 'n' (not case sensitive) in a given text.

Sample Solution:

Java Code:

import java.util.*;
public class Main
{
public int endWithmOrn(String stng) 
{
  int l = stng.length();
  int ctr = 0;
  stng = stng.toLowerCase();
  for (int i = 0; i < l; i++) 
  {
    if (stng.charAt(i) == 'm' || stng.charAt(i) == 'n') 
	{
      if (i < l-1 && !Character.isLetter(stng.charAt(i+1)))
        ctr++;
      else if (i == l-1)
        ctr++;
    }
  }
  return ctr;
}

public static void main (String[] args)
    {
      Main m= new Main();
      String str1 =  "mam is in the room";
      System.out.println("The given string is: "+str1);
      System.out.println("The number of words ends eith m or n is: "+m.endWithmOrn(str1));
	  }
}

Sample Output:

The given string is: mam is in the room
The number of words ends eith m or n is: 3
