Good day, first time poster here. I've been working on homework involving a fish tank gui that generates and displays fish swimming in a 800 by 500 tank. The issue at hand is that now I must add to the frame something on the bottom that displays information. My problem is that our class had been given almost no training in working with a gui or instructions and all my attempts leave me with a mess of code and no visible jpanel or container. At best I just end up with an area where the panel would go but with nothing displaying and a blue background. What would it take for me to at least add to the bottom of the tank a visible jpanel that I can add components to?
Here is the code I was provided for the gui:
package fishtank.view;
import fishtank.model.Fish;
import fishtank.model.Tank;
/**
* GUI frame for the fish tank that displays the frame and places the fish
* within it.
*
*/
public class FishTankGUI extends JFrame {
private Tank tank; //Class that generates the fish onto the frame.
// Required as JFrame implements Serializable interface
private static final long serialVersionUID = 1L;
private static final int REFRESH_TIME_MS = 500;
/**
* Default constructor that sets up the GUI frame.
* @param width
* The width of the frame
* @param height
* The height of the frame
* @param titleBarText
* The text to display on the title bar
*/
public FishTankGUI(int width, int height, String titleBarText) {
super(titleBarText);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setSize(width, height); //another class defines this as 800 by 500.
setResizable(false);
setVisible(true);
}
/**
* Fills the tank and puts it in motion.
* <p>
* Precondition: none
*/
public void start() {
this.setupTank();
this.animateTank();
}
/**
* Fills the tank and puts it in motion.
* @param totalFish
* The number of fish to place in the tank.
*/
public void start(int totalFish) {
this.setupTank(totalFish);
this.animateTank();
}
private void setupTank() {
TankPane tankPane = new TankPane();
getContentPane().add(tankPane);
getContentPane().validate();
this.tank = new Tank(tankPane);
}
private void setupTank(int totalFish) {
TankPane tankPane = new TankPane();
getContentPane().add(tankPane);
getContentPane().validate();
this.tank = new Tank(tankPane, totalFish);
}
private void animateTank() {
if (this.tank == null) {
this.setupTank();
}
while (true) {
this.pause(REFRESH_TIME_MS);
this.tank.moveFish();
}
}
private void pause(long milliseconds) {
if (milliseconds <= 0) {
throw new IllegalArgumentException("milliseconds is out of range.");
}
try {
Thread.sleep(milliseconds);
} catch (InterruptedException ie) {
System.err.println(ie);
}
}
}
Any help that can be provided, even the slightest amount, would be greatly appreciated!
