I would like to multiply the amount stated inside program by user input. I currently have
public static void setTicket(double ticket)
{
//if statement for tickets
if (ticket == 1)
Ticket = 10.00;
else if (ticket == 2)
Ticket = 20.00;
else if ( ticket == 3)
Ticket = 30.00;
The user should enter 2 and the value should show 20.00. This does work however im looking for a way to say enter 2 = 2*10 instead of stating each value individually.
Write a java program that will ask a user to input grades until the user inputs the sentinel value -1. The program should test each input to determine whether 0<=grade<=100. If the grade entered is within this range, the program should print "Grade accepted;" if not, the program should print "Invalid input".
I have been struggling with this program for weeks. This program is supposed to take a user's inputted odd number and then print out all prime numbers lower than that number.
public class PrimeNumber { Scanner scan = new Scanner(System.in); int userNum; String neg;
class Client{ public static void main(String []args){ Bike R1=new Bike(5.0, 60.0,30.0);//create bike object with params Bike R2=new Bike();//without params System.out.println(R1.increaseSpeed());//calling methods System.out.println(R1.maxDistance()); System.out.println(R2.increaseSpeed()); System.out.println(R2.maxDistance()); } }
Develop a method that accepts as data input three integer numbers, calculates the sum and the product of the numbers, and displays the sum and product.
My assignment is to write some code that will multiply every number in an array by 2 and print it out. This is using a site zyante which is a interactive online book kind of thing.
I have tried For (i=0; I < 8; i++) with like userVals = userVals * 2) }
And it doesn't like that so i'm guessing i am no where close to right. The chapter doesn't give me any example of doing anything close to this so i am completely lost on what i have to do.
This is the program :
import java.util.Scanner; public class NegativeToZero { public static void main(String[] args) { Scanner scnr = new Scanner(System.in); final int NUM_ELEMENTS = 8; // Number of elements
public static void main (String [] args) { int a = (int) 0.25; int b = (int) 1.25; int result = a + b; System.out.println("Result of addition is "+ result); } }
I am trying to make a program to multiplies two numbers without using the "*" operator. My idea was to add x number y amount of times, which is the same as multiplication. I did this with a for loop, but zero is always returned as the answer. How can I fix this?
public class secondMult { public static void main(String[] args){ System.out.println(multWithSum(4,5)); } public static int multWithSum(int x, int y){ int sum = 0; for(int i = 0; i==y;i++){ sum = sum + x; } return sum; } }
I was suppose to create a simple Java program for calculating the area of a rectangle (height * width). Then check the user’s input, and make sure that they enter in a positive integer, and letting them try again if they enter in a negative number. (I'm not sure how to get them to try again.
I am suppose to use an "if" statements and indeterminate loops to achieve the solution. The program will have the following requirements:
1. Ask the user to enter in both a height and width (as an integer) 2. If the user enters in a negative number, display an error 3. If the user enters in a negative number, give them another chance to enter in the correct value 4. Calculate the area and display to the screen once two positive integers have been entered.
import java.util.Scanner; public class RectangleAreaCalc { public static void main(String[] args) { int length; int width; int area;
I have been coding in my class at school (Grade 11 Computer science) and i just downloaded the program on my computer at home, unfortunately i cannot access my computer notes at home and i also dont remember certian specifics of coding, so my question is how would i get user input to create a program. The comments are the parts i dont remember. (I am trying to slowly build my memory with this stuff)
Here is my code so far:
import java.util; [highlight=java] public class hello_world { public static void main(String[] args) { string name; //WHAT DO I PUT HERE????
I'm working on creating a dice game and getting the users input is giving me a really hard time. I have the main game working but this part I'm stuck on. The problem is that it's not giving me the chance to enter the second input when I ask for the game.
//Create Scanner object Scanner keys = new Scanner(System.in); //Get chips
[Code]....
*****This is what I get when I run it
run:
How much money would you like to change? 50
You now have $50 in chips.
What game do you want to play? You did not pick dice.
I have been given a piece of work to do for College that requires me to format user input. For example: This is an example of text that will have straight left and right margins after formatting
The user inputs the width, in the case above being 20. Each line has to therefore be 20 characters long. All spaces are to be replaced with full stops.
This.is.an.example.o f.text.that.will.hav e.straight.left.and. right.margins.after. formatting.......... public class Main { public static void main ( String args[])
ArrayList<Integer> leftCU = new ArrayList<>(); { System.out.println ("Please enter one at a time the number of CU's for each class that is left to complete. Enter Q when done."); leftCU.add(in.nextInt());

I created a scanner object but it's not asking for any input. when I create a new scanner and then tell it to print it it just prints a bunch of weirdness when AFIK it should be asking me to type something and then it should repeat what i entered.
I trying to get this code to get user input instead of reading from a hardcoded array. I'm getting compile errors while trying to get user input. Here's some of the code:
I have a program that asks you for your password and if it is incorrect it reduces your attempts until you are at zero, but I want to be able to tell the user what passwords they have attempted when they run out of attempts. I've tried a couple of things but how to get it to work. This is my code:
import javax.swing.JOptionPane; public class PasswordV4 { //Begin Class public static void main(String[] args) { //Begin main program //initialize variable int passwordAttempt = 5; int value = 0;
I am new to java and I am trying to write a program where someone has to guess the number. The correct number is 3. If they are below three. It tells them that they are too low and to guess again. If they are too high, it tells them they are too high and to guess again.
However, I am having problems once they enter a number and they get the response "The number was too low. Try again" as it lets them try again but doesn't tell them if it's right, wrong, or too high. I'm not sure what piece of code I am missing. Here is what I have so far:
import java.util.Scanner; public class Guessthenumber { public static void main(String[] args) { Scanner input = new Scanner(System.in); System.out.println("Enter a number between 1-10."); double value = input.nextDouble(); if(value == 3)
