Write a method that counts the occurrences of each digit in a string using the following header: public static int[] count(String s) The method counts how many times a digit appears in the string. The return value is an array of ten elements, each of which holds the count for a digit. For example, after executing int[] counts = count("12203AB3"), counts[0] is 1, counts[1] is 1, counts[2] is 2, and counts[3] is 2. Write a test program that prompts the user to enter a string and displays the number of occurrences of each digit in the string. Here is a sample run: Enter a string: 23231adbc1234 2 Digit 1 occurs 2 times Digit 2 occurs 3 times Digit 3 occurs 3 times Digit 4 occurs 1 time
package Lab_4;
import java.util.Scanner;
public class CountDigitOccurrence {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.print("Enter a string : ");
String string = input.next();
input.close();
int[] counts = count(string);
for (int i = 0; i < counts.length; i++) {
if (counts[i] > 0) System.out.println("Digit " + i + " occurs " + counts[i] + " times");
}
}
public static int[] count(String s) {
int [] counts = new int[10];
char[] individual = s.toCharArray();
int counter = 0;
for (int i = 0; i < counts.length; i++) {
for (int j = 0; j < individual.length; j++) {
if (Character.isDigit(individual[j]) && i == Character.getNumericValue(individual[j])) {
counter++;
}
}
counts[i] = counter;
counter = 0;
}
return counts;
}
}
Please write code in C++ and include all headers not bits/stdc: 17.10 (Occurrences of a specified character in a string) Write a recursive function that finds the number of occurrences of a specified letter in a string using the following function header. int count(const string& s, char a) For example, count("Welcome", 'e') returns 2.

Problem 1.Write a program that prompts the user to enter the number of milliseconds and converts the milliseconds to a string hours:minutes:seconds. The program should use the convertMillismethod with the following header:public static String convertMillis(long millis)For example, convertMillis(5500) returns the string 0:0:5, convertMillis(100000) returns the string 0:1:40, andconvertMillis(555550000) returns the string154:19:10.Problem 2. (Count occurrence of numbers)Write a program that reads integers between 1 and 100 and counts the occurrence of each (you should store the numbers in an array). Output...

Question 1: Write a method that computes and returns the area of a square using the following header: public static double area ( double side) Write a main method that prompts the user to enter the side of a square, calls the area method then displays the area. Question 1a: Write a method that converts miles to kilometers using the following header: public static double convertToKilometers (double miles)...
This needs too be in java programming language 2 Write a recursive method that parses a hex number as a string into a decimal integer. The method header is: public static int hex. 2 Dec (String hexstring) Write a pensare cam that that prompts the user to enter a hex, string & displays its decimal equivalent. Recalls Anc=1010566-110. z 490 Use the following her values to convert: BAD, BAC98, BabA73
Write code in Java. In this step, functions and methods are synonymous. You may assume that strings only contain uppercase letters A through Z. 1. Write a function as follows: o Receive a string as a parameter. o Count the length of the string Count the occurrences of each distinguishable symbol in the string (use an array or map/dictionary). o Divide the factorial of the length by the product of the factorials of the occurrences. o Return the quotient as...
I need java code for the following problem. Lab 7: Methods 1. Write a Java program called Numbers that calls the following methods and displays the returned value: Write a method called cubelt that accepts one integer parameter and returns the value raised to the third power as an integer. o Write a method called randominRange that accepts two integer parameters representing a range. The method returns a random integer in the specified range inclusive. 2. o Write a method...
Write a test program that prompt the user to enter seven numbers, stores them in an array list and do the following: 1. Displays its elements (numbers) in increasing order by invoking a method with the following header that sorts the array: public static void sort(ArrayList<Integer>list) 2. Write a method that returns and displays the sum of all numbers (elements) of the ArrayList. Using the following header: public static double sum(ArrayList<Integer>list) 3. Write a method that removes the duplicate numbers...
A. Write an Array Program Write a main program that counts the number of occurrences of the number 6.0 in a large array of doubles and then prints out the number of elements in the array and the number of values that are 6.0. Also, compute and print the average value to 7 decimal places of all the elements in the array. 1. Use a for loop. The array fArray [ is defined in a file called Lab8Adatasetx.h that will...
