Sep 16, 2014

i am currently making a game in java and currently i am working on the basic mechanics. most of it is working fine but i cannot seem to make it so when the user presses and movment key and space to fire a bullet the bullet fires in the direction they are moving. here is the code i have for movement.

public void keyPressed(KeyEvent e) {
// TODO Auto-generated method stub
int bulletx = Player.x + 100;
int bullety = Player.y + 20;
int key = e.getKeyCode();
if( key == e.VK_W){

Sudoku Is Not Working For Few Inputs

Apr 22, 2015

The thing my coding for sudoku is not working for few inputs... it works fine with all its value initially at 0, but when i place numbers more than 4 at random places it stops responding (it doesn't show any value). My assignment is to get a solved sudoku for these values:

//Sample Input:
{0,2,7,3,8,0,0,1,0},
{0,1,0,0,0,6,7,3,5},
{0,0,0,0,0,0,0,2,9},
{3,0,5,6,9,2,0,8,0},
{0,0,0,0,0,0,0,0,0},
{0,6,0,1,7,4,5,0,3},
{6,4,0,0,0,0,0,0,0},
{9,5,1,8,0,0,0,7,0},
{0,8,0,0,6,5,3,4,0}

My current code

public class Sudoku {
static int userGrid[][]=new int[][]
{{0,0,0,0,0,0,0,0,0},
{0,0,0,0,0,0,0,0,0},
{0,0,0,0,0,0,0,0,0},
{0,0,0,0,0,0,0,0,0},
{0,0,0,0,0,0,0,0,0},
{0,0,0,0,0,0,0,0,0},
{0,0,0,0,0,0,0,0,0},
{0,0,0,0,0,0,0,0,0},
{0,0,0,0,0,0,0,0,0}};//[horizontal][vertical]
static int grid[][]=new int[9][9];//the grid that the program experiments on

Exceptions For Multiple Inputs

Oct 29, 2014

I'm writing a program that accepts three doubles from the user, and performs calculations on them. I want to be able to handle input mismatch exceptions on each individually (i.e., if the user enters a double for the first, then a letter for the second, I'd like to be able to keep the value entered for the first, and only require that the user try again with the second, then the third, etc.)... I tried putting each input instance into its own try/catch blocks, but it always goes back to #1 when an invalid input is entered. Right now, I have all three in one try/catch:

Java Code:

package com.itse2317;
import java.util.Scanner;
import java.util.InputMismatchException;
class Triangle
{
public static double side1 = 0.0, side2 = 0.0, side3 = 0.0;

Storing Multiple User Inputs In Array

Feb 28, 2015

I need to generate a league table in Java based on results provided in the shape of user input. I have the 6 teams in an array. I need to ask the user how many wins, draws, losses each team has had.

for (String element : teams) {
System.out.println(
"Please enter the number of wins, draws and losses for " + element);
int[] wins = new int [6];
int[] draws = new int [6];
int[] losses = new int [6];
}

How do I pull 3 separate values from the user and then store each value in a separate element of each array? so if one team wins 3, draws 2 and loses 1 - I need to put 3 into the wins array, 2 into the draws array and 1 into the losses array? I then need to total all this in a table.

Text Based RPG Game - Working With Multiple ArrayLists

Feb 22, 2014

I have come across an issue with arraylists. I am writing a text based RPG game as something to start with ...

Initially I had a single zone which was all stored in an arraylist and everything was working in regards to the player moving around. The problem I now have is how to add further zones to my game. Ideally I would like an arraylist for each zone, and would use the below to create each arraylist

public static ArrayList<RoomsClass> castleMap = new ArrayList<>();

The problem I now have is how to handle the player moving, initially with a single zone/arraylist I could reference that arraylist directly

public void findRoomCoords(int ID) {
for (int i = 0; i < castleMap.size(); i++) {
if (castleMap.get(i).roomID.equals(ID)) {
PLAYER.setCurrentRoomZone(castleMap.get(i).roomZone);
PLAYER.setCurrentRoomX(castleMap.get(i).roomX);
PLAYER.setCurrentRoomY(castleMap.get(i).roomY);
PLAYER.setCurrentRoomZ(castleMap.get(i).roomZ);
}
}
}

My initial thought was to use a getter/setter to remove the reference of castleMap from my movement code in order to access different arraylists, however this is where things have fallen over, I can't seem to work out how to get the arraylist name to change, depending on the outcome of the setZoneMap() method.

public void setZoneMap() {
switch (PLAYER.getCurrentRoomZone()) {
case 0: {
zoneMap = Castle.castleMap;
break;

Calculations On Text Box Inputs

Mar 7, 2014

I have made a simple form, it consists of 3 text box's textbox1, textbox2 and textbox3 as well as 1 button button1. What I want to be able to do is put numbers into textbox 1 and 2 and then show the multiplication of these numbers in textbox 3 when the button is pressed and I was wondering what is the standard way of reading these numbers from the text box and allowing us to do the conversion obviously in the textbox its a string and we need to convert to an int or double or whatever to be able to perform calculations on them then convert it back into a string to display in text box 3?

Reading Inputs Using Buffered Reader

Oct 13, 2014

I am trying to read the following input (which will be inputted by the user when run) using the BufferedReader approach:

1
*** * * * *** *** *** ***
* * * * * * * * *
* * * *** *** *** *** ***
* * * * * * * * *
*** * * *** *** *** ***

I am reading each line of the input one line at a time and incrementally storing four char positions into an array, so i am able to hold a vertical representation of each column. I.e. column 1 will be stored in array[0].

The problem with my code is that is does not read the last line of the input, it reads all the other inputs before it but just refuses to read the last line and execute the procedure of storing the characters.

Code:

public void defuseBomb(){
try {
BufferedReader reader = new BufferedReader(new InputStreamReader(
System.in));
String asciiLine = reader.readLine()+ " ";
int digit = (asciiLine.length())/4;

Anomaly While Using Scanner Class For Taking Inputs

Feb 1, 2015

There is a problem that I am facing while using the Scanner class for taking inputs from the user. Suppose if I need to take an integer and a String input from the user, and I take the integer input first then the place where the user has to input the String skips and the variable shows a "" nothing on printing it. Suppose in this code snippet

import java.util.Scanner;
public class Test
{
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
System.out.println("Enter a number");
int n = sc.nextInt();
System.out.println("Enter a word");
String str = sc.nextLine();
System.out.println("Enter integer is " + n);
System.out.println("Entered statement is " + str);
}
}

The output is
Enter a number
13
Enter a word
Enter integer is 13
Entered statement is

I need to know why this happens and how should I avoid it. I've seen that taking the String input first solves the issue but while taking the input in a loop to populate a database the program only lets the user enter the first statement and the following statements are skipped.

Return A String That Holds User Inputs

Apr 18, 2015

I'm working on an assignment for my Java Programming class that requires me to work with Multiple Classes.

Overview of the assignment: Create a "Database" that allows a user to input information about a College Class.

My program has three Classes:

The information that must be tracked in the Course Class is:
- Section Number
- Instructor
- Classroom
- Students (an ArrayList of class Student)

The information that must be tracked in the Student Class is:
- Name
- Major
- GPA
- Hours

The Driver class will use the main method to print the user a prompt asking for inputs, then display all of the user's inputs after he/she wished to exit the program.

I'm having no trouble with asking the user for inputs and then checking the validations for the inputs, I'm currently struggling with return a String that houses all of the user's inputs for the variables above. The information must be returned in a method called toString(). Both the Student and Course Class must have a toString() method that returns the information in the class (value of the variables), I must then call upon these methods from the main method of the Driver Class to print them back to the user.

The toString methods within the Student & Course Classes are at the bottom of the code

To Summarize: What I need to do within the toString() methods to return the values the user has inputted for the various variables? Such as.. Should I pass something through the method? Do I need the this keyboard to pass through the variable again? I just fear that I'm currently misunderstanding a very critical part of programming.

My Driver Class

import java.util.Scanner;
public class Driver {
Course courseInputs = new Course();
Student studentInputs = new Student();
public static void main(String[] args) {

[Code] .....

can count the numbers from 0-9 if the user puted but if it is 10 it doesnt count it , and i need to write all the numbers to have that option. . . . Is there an easy way that includes all the numbers? like if(word.equals(number)){<<<???? (numbers) i know htat doesnt work but is there anything similar ?? ??

countNumbers++;
}
System.out.println("Type Something , , , and to end the the termination type STOP");
word=input.nextLine();
count++;
}
System.out.println("You wrote "+count+" lines wich from those lines "+countNumbers+" were numbers and the programe terminated ");

Developing A Program That Inputs Telephone Numbers

Jan 26, 2014

Develop an algorithm for a Java program that takes as input a single letter and displays the corresponding digit on the telephone. The letters and digits on a telephone are grouped this way:

2 = ABC 3 = DEF 4 = GHI 5 = JK 6 = MNO 7 = PQRS 8 = TUV 9 = WXYZ

The screen dialog might look like this: Enter a single letter, and I will tell you what the corresponding digit is on the telephone. R The digit 7 corresponds to the letter R on the telephone.

The program should display a message indicating that there is no matching digit for any non-alphabetic character entered by the user. Also, the application should recognize only uppercase letters. If a user enters a lowercase letter, the program should display an error message. Prompt the user with an informative message for the input value as shown above.

The application should include the input letter as part of the output.

Write the algorithm to solve this problem including steps for prompting the user, getting input from the keyboard, and displaying the results.

Write the Java program that you designed, using your algorithm as a guide. Use your algorithm as comments in the body of the main method.

Use proper indentation, and meaningful identifiers throughout the code.
