Java Sockets - Unable to enter second input on client side [EDIT] - java

I am trying to make a Connect 5 game, where the game logic is held on the server side, with the client side influencing the current game state. So far, I have the game logic implemented and it works just fine if you were to run it. I am running into issues when trying to implement the actual client/server sider of things.
I am not exactly sure how to go about doing it. What I can do at the moment is get the player names and the size of the board. When it comes to actually playing the game, I run into some issues such as keeping the game running and getting the player's move. Currently the server will stop running after a short period of time. I have tried using a while(true) to keep it running but it doesn't seem to work.
Another issue is displaying the actual board on the client side - while I am able to display the board if you were to just play the game from the server class using System.out.println(fiveInARow);, which displays the board after every move. I have tried using How to send String array Object over Socket? to display the board (testing if I can even just get the empty board at the start of the game to display on the client side), I get an error.
Should I be doing something like How to get input from Console in Java Client Server Program to get an input from the user inside the for (int player = 0; moves-- > 0; player = 1 - player)?
UPDATED: So I'm able to make a move and the move will be played accordingly. However, the second player is unable to make a move (unable to enter input on client side after first input).

Passing Values from Constructor to a Method

My project requires me to make a game where two space ships move around on a game board. I'm not too sure on how to get my X and Y position values from my constructors to my method in my main program.
I got a bit of help from my professor and he said to pass the X and Y values into my print board method I tried to use ship1.XPos, ship1.YPos, ship2.XPos, ship2.YPos in my print board declaration but I got an error about VariableDeclaratiorId.
Here is my main as it is currently as is right now
Java
package ship;
import java.util.*;
public class ShipGame {
public static String[][] makeBoard() {
String[][] f = new String[6][22];
for (int i = 0; i < f.length; i++) {
for (int j = 0; j < f[i].length; j++) {
if (j % 2 == 0)
f[i][j] = "|";
else
f[i][j] = " ";
}
}
return f;
}
public static void printBoard(String[][] f, ship1.XPos, ship1.YPos, ship2.XPos, ship2.YPos) {
for (int i = 0; i < f.length; i++) {
for (int j = 0; j < f[i].length; j++) {
if(x == ship1.XPos && y == ship1.YPos){
System.out.print(ship1);
}
else if (x == ship2.XPos && y == ship2.YPos){
System.out.ptint(ship2);
}
else{
System.out.print(f[i][j]);
}
System.out.println();
}
}
}
public static void main(String[] args) {
int engine;
System.out.println("Welcome First Captian! What kind of ship would you like to create: ");
System.out.println("1. Battlecruiser");
System.out.println("2. Destroyer");
Scanner scan = new Scanner(System.in);
engine = scan.nextInt();
scan.nextLine();
String engineType;
if (engine == 1) {
engineType = "Battlecrusier";
}
else {
engineType = "Destroyer";
}
System.out.println("What would you like to name your vessel?");
String shipName1 = scan.nextLine();
Spaceship1 ship1 = new Spaceship1(shipName1, engineType);
System.out.println("Welcome Second Captian! What kind of ship would you like to create: ");
System.out.println("1. Battlecruiser");
System.out.println("2. Destroyer");
engine = scan.nextInt();
scan.nextLine();
if (engine == 1) {
engineType = "Battlecrusier";
}
else {
engineType = "Destroyer";
}
System.out.println("What would you like to name your vessel?");
String shipName2 = scan.nextLine();
Spaceship2 ship2 = new Spaceship2(shipName2, engineType);
String[][] f = makeBoard();
int count = 0;
printBoard(f);
boolean gaming = true;
while (gaming) {
if (count % 2 == 0) {
ship1.movement1(f);
}
else {
ship2.movement2(f);
}
count++;
printBoard(f, ship1.XPos, ship1.YPos, ship2.XPos, ship2.YPos );
gaming = false;
}
}
}
Here is my Spaceship1 constructor. It is the same as my Spaceship2 constructor so there's no need to add it
Java
package ship;
import java.util.Random;
import java.util.Scanner;
public class Spaceship1 extends ship {
private String ship1;
public Spaceship1(String shipName, String engineType) {
super(shipName, engineType);
double maxSpeed = Math.random() * 2 + 1;
int shipHealth = (int) (Math.random() * 100 + 50);
int attackPower = (int) (Math.random() * 20 + 5);
Random rand = new Random();
int newXPos = rand.nextInt(9);
int newYPos = rand.nextInt(9);
setShipHealth(shipHealth);
setMaxSpeed(maxSpeed);
setAttackPower(attackPower);
setXPos(newXPos);
setYPos(newYPos);
}
public void movement1(String[][] f) {
System.out.println("W Move Up");
System.out.println("S Move Down");
System.out.println("A Move Left");
System.out.println("D Move Right");
Scanner scan = new Scanner(System.in);
String move = scan.nextLine();
int standX = getXPos();
int standY = getYPos();
double standS = getMaxSpeed();
if(move == "W")
{
standY += standS;
setYPos(standY);
}
else if(move == "S")
{
standY += standS;
setYPos(standY);
}
else if(move == "A")
{
standY += standS;
setYPos(standY);
}
else if(move == "D")
{
standY += standS;
setYPos(standY);
}
}
}
I expect there to be the words Ship1 and Ship2 on any space on my game board that is declared as 6x22.
When you define a method, you need to define the arguments it accepts using their types and names that the method will use to refer to those arguments. For example, your code:
public static void printBoard(String[][] f, ship1.XPos, ship1.YPos, ship2.XPos, ship2.YPos)
should actually be written like so:
public static void printBoard(String[][] f, int ship1Xpos, int ship1Ypos, int ship2Xpos, int ship2Ypos)
The reason your code doesn't work is because you're trying to define the method using the values you want to pass into it (e.g., ship1.XPos). When you want to call the method, then you can give it the values that you want it to use, like so:
printBoard(f, ship1.XPos, ship1.YPos, ship2.XPos, ship2.YPos);
Keep in mind that you also have the following line of code which won't work because you're not passing a value for all of the arguments it expects:
printBoard(f);

Why do object arrays in my ArrayList fail to retain their values?

I am creating a program in Java to simulate evolution. The way I have it set up, each generation is composed of an array of Organism objects. Each of these arrays is an element in the ArrayList orgGenerations. Each generation, of which there could be any amount before all animals die, can have any amount of Organism objects.
For some reason, in my main loop when the generations are going by, I can have this code without errors, where allOrgs is the Organism array of the current generation and generationNumber is the number generations since the first.
orgGenerations.add(allOrgs);
printOrgs(orgGenerations.get(generationNumber));
printOrgs is a method to display an Organism array, where speed and strength are Organism Field variables:
public void printOrgs(Organism[] list)
{
for (int x=0; x<list.length; x++)
{
System.out.println ("For organism number: " + x + ", speed is: " + list[x].speed + ", and strength is " + list[x].strength + ".");
}
}
Later on, after this loop, when I am trying to retrieve the data to display, I call this very similar code:
printOrgs(orgGenerations.get(0));
This, and every other array in orgGenerations, return a null pointer exception on the print line of the for loop. Why are the Organism objects loosing their values?
Alright, here is all of the code from my main Simulation class. I admit, it might be sort of a mess. The parts that matter are the start and simulator methods. The battle ones are not really applicable to this problem. I think.

The problem lies in the graphOrgs class when I try to print to check if it is working in preparation for graphing the results. This is when it returns the error. When I try placing the print code in other places in the Simulator class the same thing occurs, a null pointer error. This happens even if it is just after the for loop where the element has been established.
You have code that sets to null elements in your allOrgs array.
allOrgs[partner1] = null;
allOrgs[partner2] = null;
Your orgGenerations list contains the same allOrgs instance multiple times.
Therefore, when you write allOrgs[partner1] = null, the partner1'th element becomes null in all the list elements of orgGenerations, which is why the print method fails.
You should create a copy of the array (you can use Arrays.copy) each time you add a new generation to the list (and consider also creating copies of the Organism instances, if you want each generation to record the past state of the Organisms and not their final state).

I have tried the above code for bigramizing the words in the file "input.txt" i have got the result of bigram but i didnt get the similarity value.
for e.g:
input file contains as
answer:
high
risk
simulate
behaviour
solution
set
rules
[2]
rules
outline
high
source
knowledge
[1]
set
rules
simulate
behaviour
in the above example I have to compare the words under answer with every word under [2] as {high,rules} {high,outline} {high,high} {high,source} {high,knowledge} and I have to store the maximum value of the above comparison and again the second word from answer is taken and then similar process is taken. At last, mean of maximum value of each iteration is taken.

Text file load error and array error on mouse island application

I have a problem, I am not looking for answers to my problem I would like some help finding why my array even though specified in main unders switch: case1, case2, case3. I used a for loops with an array that stops at the 5th iteration. However when I run the program it only runs once, am I specifying correctly to make it run 5 times or should it be declared another way? thanks in advance. I should also include there are no errors reported by eclipse at this time until it is ran and only after the first input.
The text files contains
##B##

The island maps can be found here
[http://rapidshare.com/share/9704FE33EFF98F1C1E71F6F1DF2DC0D4]
This is the array (int i=0;i<5;i++) however I do not think this is the problem, I can also provide the text files if needed
This is the console out

Numbering A Crossword Java ACM Graphics

The problem asks for an acm graphics program that reads a txt file like this:
R
FUN
SALES
RECEIPT
MERE#FARM
DOVE###RAIL
MORE#####DRAW
HARD###TIED
LION#SAND
EVENING
EVADE
ARE

and makes a crossword puzzle, with blank squares on letters, black squares on '#', and nothing on empty spaces. The problem also asks that "if the square is at the beginning of a word running across, down, or both, the square should contain a number that is assigned sequentially through the puzzle."
I have the square drawing working, but I'm stuck on drawing the numbers correctly. There is something wrong with how I'm detecting null space and black squares. Can someone tell me what I'm doing wrong, please?
Here is the code:
import acm.program.*;

import acm.graphics.*;

public class Crossword extends GraphicsProgram {

private int y = 0;
public void makeCrosswordPuzzle(String fileName) {
BufferedReader rd;
int y = 0; // y value for the square being added during that loop. increments by sqCon after every line
int wordNumber = 1; // variable for numbers added to certain boxes. increments every time the program adds a number
try {
rd = new BufferedReader(new FileReader(fileName));
String line = rd.readLine(); //reads one line of the text document at a time and makes it a string
while (line != null) {
int x = 0;
for (int i = 0; i < line.length(); i++) {
char lineChar = line.charAt(i);// the character being examined for each loop
GRect whiteSq = new GRect(sqCon,sqCon); //GRect for blank squares
GRect blackSq = new GRect(sqCon,sqCon);//GRect for black squares
blackSq.setFilled(true);
blackSq.setFillColor(Color.BLACK);
if (lineChar == '#'){
add (blackSq,x,y);
}
if (Character.isLetter(lineChar)) {
add (whiteSq, x, y);
// if the element above or to the left of the current focus is null or blackSq, place the number and then increment wordNumber
GObject above = getElementAt(x+sqCon/2,y-sqCon/2);

I followed the advice of my own comment. I created the crossword puzzle answer, numbered the crossword puzzle answer, and finally drew the crossword puzzle answer.
Here's the applet result:
I kept a List of crossword puzzle cells. That way, I could determine the length and the width of the puzzle by the number of characters on a row and the number of rows of the input text file. I didn't have to hard code the dimensions.
For each crossword cell, I kept track of whether or not it was a letter, and whether or not it was a dark space.
When determining where to put the numbers, I followed 2 rules.
An across number is placed where the cell left of the cell is empty or dark, and there are three or more letters across.
A down number is placed where the cell above the cell is empty or dark, there are three or more letters down, and there is no across number.
You can see in the code that I had to do some debug printing to get the crossword puzzle clue numbering correct. I broke the process into many methods to keep each method as simple as possible.
Finally, I drew the crossword puzzle answer from the information in the List.
Here's the code:
