Write a program whose input is a character and a string, and whose output indicates the number of times the character appears in the string. Ex: If the input is: n Monday, the output is:

import java. util. Scanner;

public class ANot {

public static void main (String[] args) {

System. out. println ("Enter a character");

Scanner in = new Scanner (System. in);

char character = in. next (). charAt (0);

System. out. println ("Enter a string");

String string = in. next ();

//Calling the method

System. out. println (countChar (character, string));

}

public static int countChar (char a, String in) {

int counter = 0; / / initialize counter

for (int i=0; i
if (a = = in. charAt (i))

counter++;

}

return counter;

}

}

Explanation:

This program is written in Java Programming language.

We created a method countChar that returns a integer called counter

Using a for loop in the method we iterate through the string object and check (a = = in. charAt (i)) so as to increase counter when ever there is a match.

In the main method a Scanner Class is used to request user to input a character and a string which is passed to countChar when called.

NOTE that this program has considered lower case letters to be different from upper cases as such a is not equal to A
