Question

Write a program whose input is a string which contains a character and a phrase, and whose output indicates the number of times the character appears in the phrase. Ex: If the input is: n Monday the output is: n appears this many times: 1 Ex: If the input is: z Today is Monday the output is: z appears this many times: 0 Ex: If the input is: n It's a sunny day the output is: n appears this many times: 2 Case matters. Ex: If the input is: n Nobody the output is: n appears this many times: 0

Answer 1

Answer:

import java.util.Scanner;

public class NumberOfOccurences {

public static void main(String[] args) {

 // Create an object of the Scanner class to allow for user inputs

 Scanner input = new Scanner(System.in);

 // Prompt user to enter text

 System.out.println("Please enter the phrase");

 // Store text in a variable

 String phrase = input.nextLine();

 // Prompt user to enter character to be checked

 System.out.println("Please enter the character to check");

 // Store character in a char variable

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

 // Create and initialize a variable count to zero

 // count will hold the number of occurrences of the character in the phrase

 int count = 0;

 // Loop through each of the character in the string text

 // At every cycle of the loop, compare the character of the string

 // with the character to be checked.

 // If they match, count is incremented

 for (int i = 0; i < phrase.length(); i++) {

  if (phrase.charAt(i) == character) {

   count++;

  }

 }

 // Print out the number of occurrences due to count

 System.out.println(character + " appears this many times " + count);

}

}
