How To Make Line To Follow Rectangle When Moving Or Rotating
Oct 18, 2014After i draw line between 2 fixed points on two different rectangles i need to rotate them. The problem is that my line is not updated, it stays on the same x1,y1 x2,y2. How to make line to follow rectangle when they are moving or rotating? I wrote some example code to demonstrate this.
Object that i want to draw:
[public class Object {
private int xPos;
private int yPos;
private int width;
private int height;
float xDistance = 0f;
float yDistance = 0f;
double angleToTurn = 0.0;

Eclipse - Coding Multiple If / Else Statements
Apr 22, 2015What I am attempting to program is a simple Boss battle. I would like the user to have 2 options (for now): Run, or Attack. I got the portion completed and working, but once I tried to implement the Run feature (the way that it's supposed to work is you can either attack OR run), both Attack and Run will happen. Also, for some reason, the running always fails (it will always return the else statement, then move onto the attack.) Here's my code:
import java.util.*;
public class AdvancedBossBattle {
public static void main (String[] args) {
Scanner scan = new Scanner (System.in);
Random gen = new Random();
int bosshp, bossdmg, playerhp, playerdmg, runChance;
String answer;
bosshp = 100;

How Curly Braces Follow Assignment Statement
Apr 7, 2015@Override
@SuppressWarnings("unchecked")
public TableCell<S, T> call(TableColumn<S, T> p) {
TableCell<S, T> cell = new TableCell<S, T>() {
@Override
public void updateItem(Object item, boolean empty) {
if (item == getItem()) {
return;
}
The line in the code above TableCell<S, T> cell = new TableCell<S, T>() {
I don't understand how curly braces follow an assignment statement?What does the line of code mean?
How To Make Robot Print Out Colons
May 1, 2014I've tried making my robot print out colons but I just can't seem to. I tried doing
Java Code:
robot.keyPress(KeyEvent.VK_COLON); mh_sh_highlight_all('java');
and
ava Code:
robot.keyPress(KeyEvent.VK_SHIFT);
robot.keyPress(KeyEvent.VK_SEMICOLON); mh_sh_highlight_all('java');
And neither seem to work, in fact I can't seem to get any symbols typed out (I don't want to copy to clipboard and paste out) (yes, I do keyRelease as well -> I've tried a bunch of stuff)...

Program To Simulate Operation Of Simple Robot
Apr 26, 2015Write a program to simulate the operation of a simple robot. The robot moves in four directions: Forward, backwawrd, left, and right. The job of the robot is to move items and place it in the right slots in each station. There are 8 stations plus the pickup station. Pick up station is the initial start where the robot picks the items. 8 items can be placed on each station. The nearest station must be filled before placing items on the next station. The items are marked with identification or serial numbers. The items with odd serial number go to the right and items with even number go to the eft. The last slot, number 7 is reserved for light items which are less than 80kg. The serial number is a five digit number, the MSB digit 5 indicates that the product must be placed in the fifth station which is keeping the product at 20 degree F.

How To Make File Reader Object Move To Next Line If There Is No More Input On Line
Feb 18, 2015How do I make the file reader object move to the next line if there is no more input on the line. Here is my text and output file as you can see that my text file column cuts off on the 2nd line after 70. I want to read that next line which is 100 into my labs variable however its reading it into my final exams variable. I'll also post the code but I didn't think it was necessary.
textfile:

Find A String And Display Line Number And Line Itself?
Oct 20, 2014I'm creating a program that searches a txt file for a given string, then return the number line and the line itself. However, my testFile class isn't detecting my searchWord methods.
The searchWord and recursiveSearch is written in a java class called BasicFile
public List<String> searchWord(String key) throws Exception {
LineNumberReader lnr = new LineNumberReader(new FileReader(f));
return recursiveSearch(lnr.readLine(), key, lnr);
}
public List<String> recursiveSearch(String currentLineText, String key, LineNumberReader lnr)
[code]....
Is it because I'm using a list instead of a string?
Scanning Next Line Of Input Without Advancing Past Line
Apr 12, 2014I'm doing an assignment for uni and have come across a small hiccup. What I'm trying to do is scan in a text file and read "commands" for it line by line, E.g:
Student Mary 12345 19
Student Joe 12346 19
Change Joe 19 20
Change Mary 19 20
So that lines that begin with the word "Student" indicate that I should create a new student file with that name, student ID, and age.
"Change" indicates that I should be changing the specified student's current age to the new age etc.
What I'm currently doing is something along the lines of this:
Scanner input = new Scanner(new FileReader(args[0]));
String[] line;
while (input.nextLine().startsWith("Student")) {
line = input.nextLine().split("s+");
[Code] ....
The problem I'm having is that every second line seems to be getting skipped (because I'm calling nextLine() so much?) but I can't think of a way to "peek" at the first word of each line without advancing past it. Is there any way of doing this?

Jun 9, 2014public int getIndexOfAMonster(String nameToGet){

for (int i = 0; i <= numberOfMonsters - 1; i++)
if (monsters[i].getName().equals(nameToGet))

}
1.What does the if-condition do?If the name of a monster in the array is equal to the name stored in the variable, return the monster's assigned value.
2.What does the for loop do? The loop condition simply loops through the whole arraylists. (In other words, it simply checks each Monster contained in the lists).
3.Assuming that the driver code compiles, explain what it’s use is? If the name of the monster is the same as the variable passed unto this method, return the number assigned to that Monster.
Coding AI Game Through Java
Apr 10, 2015The game has two players: x and o. The players take alternate turns, with player x moving first at the beginning of each game.
Player x starts at position (1,1) while o starts at (8,8).
Each turn, a player can move like a queen in chess (in any of the eight directions) as long as her path does not cross a square already filled in or occupied. After moving, the space vacated by the player is designated as filled and cannot be moved to again. Notice that only the space that was occupied is filled, not the entire path.
The game ends when one player can no longer move, leaving the other player as the winner.
The coordinate (1 1) indicates the top left hand side of the board.
The board is specified as a list of rows. Each row is a list of entries:
- is an empty square * is a filled in square x is the current position of the x player o is the current position of the o player
The board will always be 8 by 8.
Your player function should take in the parameters as described above and return a move as a list in the format (row column) within 1 minute. If you cannot move, return (nil nil). The Tournament Referees will check for this. If you return an illegal move, the other player (and the Tournament Referees) will detect it and you will lose.
Additionally if your time expires you will lose.

View Replies View RelatedJava Coding For Constructors And Input
Oct 25, 2014I was required to make a program that contains 3 data fields, 2 constructors, and 4 methods. I'm having a hell of a time trying to put some input into this, where the user would choose from 1 of the 3 data fields I made up for car prices and choose their vehicle. As far as the constructors go, I made a default one but I'm not sure on how to A) implement another constructor and how do I involve the input into this and C) where the methods go in that.
I'm thinking of putting the input first but that ruins my constructors? I realize I asked a lot, but this is an online class without a text, and I'm basically starving for knowledge. [code]

Sieve Coding Not Pairing In Output
Apr 1, 2015When I compile the code, it goes through fine in the compiler. However after entering the boundaries for the lower an upper it doesn't produce the prime pairs between the two boundaries that the user sets. I have tried changing some of my integers that i initialized no luck. I looked at the last section of public void showPrimes() . However I can't seem to see where it has gone wrong there. I have included the entire code, plus the section again that I think is wrong. I have also posted the final output of what it looks like and what else should be included to make it easier to see what I am missing. Basically it keeps giving me zero primes even when the boundary is 100 and 200, or so and so forth.
import java.util.Scanner;
public class kbeaudry_xSieve
{
public static void main (String args[]){
kbeaudry_xSieve i = new kbeaudry_xSieve();
}
boolean primes[] = new boolean [50001];
int upper;
int lower;
[code]....
This is what i get when I actually run the program. However in the section where I have added *****, this is where it should put the prime pairs in.
Please enter a lower boundary and an upper boundary and I will print all of the sexy prime pairs between those boundaries.
Please enter the lower boundary (between 1 and 50000): 200
Please enter the upper boundary (between 1 and 50000): 600
There were 0 sexy pairs displayed between 200 and 600.. I am still working on another code for my that I had issues with, however I had to go out of the country for a few days to take care of some work.
