Thread: Bad Output

I was writing up a little game kit, when i ran into a little problem. When you enter a command, it skips past all the if/else statements, and defaults to the final else statement.

import java.util.*; //used to make imput work
 
class Text_Game_Kit
{
	//main method, where the game takes place
	public static void main(String args[])
	{
		//Declaring everything
 
 
 
		//position as a Y cordinate
		int POSY = 0;
 
		//position as an X cordinate
		int POSX = 0;
 
		//Placeholder for input
		String input = "";
 
		//The First Chest is not open
		boolean Chest1 = false;
		String Chest1OPCL = " closed"; // the first chest is closed. This is to enhance the text.
 
		//Is there an enemy?
		boolean enemy = false;
		String enemyname = ""; //Type of enemy. i.e. Skeleton, Zombie, etc.
 
		// boolean to see if the game is done
		boolean done = false;
 
		//if the game is not done, keep running
		while (!done)
		{
 
			//quickly check if the game is done. if it is, break everything
			if (done)
			{
				break;
			}
 
 
			//these are commands. try to see how they work. all commands must be lowercase.
 
			//Movement Outputs: tells the user what the character sees
 
			if (POSX==0&&POSY==0) //If you are at the starting position: 0,0. You see a chest from here. Reach it by saying "move up" 3 times.
			{
				System.out.println("You wake up in a poorly lit room. You see a" + Chest1OPCL + " chest 3 steps to the north");
			}
			else if (POSX==0&&POSY==3) //You have just moved up 3 times. you can open the chest by saing "open"
			{
				System.out.println("There is a" + Chest1OPCL + " chest in front of you.");
			}
 
 
			//Danger Commands: tells the user other information besides the Movement Outputs
			if (enemy)
			{
				System.out.println("You are being attacked by a" + enemyname + ".");
			}
 
 
			//Get the input
			input=in();
 
 
			//handle the input. This includs all do able commands. typing help will list them. typing help and then a command will describe it. The only changing here should be to add commands
 
			//Moving Commands
			if (input==("up")) 
			{
				POSY++; //move up
			}
			else if (input==("down"))
			{
				POSY--; //go down
			}
			else if (input==("left"))
			{
				POSX--; //move left
			}
			else if (input==("right"))
			{
				POSX++; //move right
			}
 
			//opening commands: deals with: is there a chest, is it open, and what happens
 
			else if (input==("open"))
			{
				if (POSX==0&&POSY==3&&!Chest1) //if the chest isnt open and you are at 0,3: the place where chest1 is.
				{
					System.out.println("You open the chest and find a sword. You hear the rattling of bones behind you.");
					enemy=true;
					enemyname=" Skeleton";
					Chest1=true;
					Chest1OPCL="n open"; //now text thinks its open
					// you open the chest and are now being attacked by a skeleton. use "attack" to kill it.
				}
 
				// you can insert more chests here, you must use else if
 
				//if there is no chest
				else
				{
					System.out.println("You see nothing to open!");
				}
 
			}
 
			//Attacking Command
			else if (input=="attack")
			{
				if (enemy)
				{
					System.out.println("You attack a" + enemyname + ". It falls rather easily.");
 
					//Staging. this is rather difficult because the attack command dosent know what you just attacked.
					if (enemyname == " Skeleton")
					{
						done=true; //in this short kit, killing the skeleton is the end. however, you can use anything here. if you want, you can make this progress, or have another enemy pop up, a door open, etc. if you need help here, just ask. I understand its a bit vague.
					}
				}
				else
				{
					System.out.println("You find nothing to attack, so you swing at the air for good measure");
				}
			}
 
			//help, and any variants. Add more if you make new commands
			else if (input=="help")
			{
				System.out.println("Commands are: up, down, left, right, open, help, and attack. Say help with a command after it to see more information"); //make sure to put any added here.
			}
 
 
			//indepth command help
			else if (input=="help up")
			{
				System.out.println("This makes you move fowdard");
			}
			else if (input=="help down")
			{
				System.out.println("This makes you move backwards");
			}
			else if (input=="help left")
			{
				System.out.println("This makes you move left");
			}
			else if (input=="help right")
			{
				System.out.println("This makes you move right.");
			}
			else if (input=="help open")
			{
				System.out.println("This opens a chest, if there is one.");
			}
			else if (input=="help attack")
			{
				System.out.println("This attacks an enemy, if there is one.");
			}
			else if (input=="help help")
			{
				System.out.println("You IQ must me in the double digits");
			}
 
			//The end of the command cycle. all other commands must be above this
			else
			{
				System.out.println("That is not a command. Try using help to find more commands.");
			}
 
 
 
		}
 
		//end of the loop. only goes here when the game is done
		System.out.println("Congradulations! You've won!");
 
	}
 
 
	//This method gets input
	public static String in()
	{
		Scanner scan=new Scanner(System.in);
		String word = "Temp";
		word=scan.next();
		return word;
	}
}

You know that strings needs to be compared using the "equals(...)" method instead of the regular "==" expression?
