Write a method called makeStars. The method receives an int parameter that is guaranteed not to be negative. The method returns

serious [3.7K]

Answer:

// import the Scanner class

// to allow the program receive user input

import java.util.Scanner;

// The class Solution is defined

public class Solution{

// main method to begin program execution

public static void main(String[] args) {

// scanner object scan is declared

Scanner scan = new Scanner(System.in);

// Prompt the user to enter a number

System.out.println("Enter the number of stars you want: ");

// user input is assigned to numOfStar

int numOfStar = scan.nextInt();

// call the makeStars method

makeStars(numOfStar);

}

// makeStars method print stars using recursion

// the method call itself till starNum == 0

public static void makeStars(int starNum){

if (starNum != 0){

System.out.print("*");

makeStars(starNum -1);

}

Explanation:

The code is well comment and solve the problem using recursion.

Which decimal value (base 10) is equal to the binary number 1012?

GaryK [48]

Answer:

The decimal value of 101₂² base 2 = 25 base 10

Explanation:

The number 101₂² in decimal value is found as follows;

101₂ × 101₂ = 101₂ + 0₂ + 10100₂

We note that in 101 + 10100 the resultant 2 in the hundred position will have to be converted to a zero while carrying over 1 to the thousand position to give;

101₂ + 0₂ + 10100₂ = 11001₂

Therefore;

101₂² = 11001₂

We now convert the result of the square of the base 2 number, 101², which is 11001₂ to base 10 as follows;

Therefore converting 11001₂ to base 10 gives;

11001₂= 1 × 2⁴ + 1 × 2³ + 0 × 2² + 0 × 2 ¹ + 1 × 2⁰

Which gives;

16 + 8 + 0 + 0 + 1 = 25₁₀.

Write a second constructor as indicated. Sample output: User1: Minutes: 0, Messages: 0 User2: Minutes: 1000, Messages: 5000

Mashcka [7]

Complete Question:

Write a second constructor as indicated. Sample output:User1: Minutes: 0, Messages: 0User2: Minutes: 1000, Messages: 5000// ===== Code from file PhonePlan.java =====public class PhonePlan { private int freeMinutes; private int freeMessages; public PhonePlan() { freeMinutes = 0; freeMessages = 0; } // FIXME: Create a second constructor with numMinutes and numMessages parameters. /* Your solution goes here */ public void print() { System.out.println("Minutes: " + freeMinutes + ", Messages: " + freeMessages); return; }}

Answer:

The second constructor is given as:

//This defines the constructor, the name has to be the same as the class //name

PhonePlan(int numOfMinutes, int numberOfMessages) {

this.freeMinutes = numOfMinutes;

this.freeMessages = numberOfMessages

}

Explanation:

The second constructor is defined using java programming language.

The given class has two constructors This is called "Constructor Overloading) which implements polymophism
In the second constructor that we created, we pass in two arguments of type integer numOfMinutes and numberOfMessages.
In the constructor's body we assign these values to the initially declared variables freeMinutes and freeMessages
