我想知道什麼使用new創建一個JLabel對象,並將其放置在數組中的相應元素中。 (grid [row] [col])的意思。我正在創建一個Tic-Tac-Toe程序。我正在使用for循環來初始化網格。 這裏就是我的for循環:數組中的對應元素
package tic.tac.toe;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class TicTacToe extends JFrame implements ActionListener, MouseListener
{
Container content = this.getContentPane();
//Program Arrays
JLabel [][] grid = new JLabel[' '][' '];
char [][ ]game = new char [' '][' '];
// Graphical User-interface Fields
JButton restart = new JButton("Restart");
JPanel p = new JPanel();
JLabel status = new JLabel("Welcome to Tic-Tac-Toe");
//Primitive Fields
int numClicks = 0 ;
boolean isDone = false;
boolean isXTurn = true;
public TicTacToe()
{//GUI
this.setVisible(true);
this.setTitle("Tic-Tac-Toe");
this.setSize(900,500);
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
//SetLayout
//Add Status Label
content.add(status);
status.setOpaque(true);
status.setBackground(Color.yellow);
status.setForeground(Color.blue);
status.setFont(new Font("Helvetica", Font.BOLD, 12));
//Initailize the Main Panel
p.setLayout(new GridLayout(3,3));
p.setBackground(Color.black);
content.add(p, BorderLayout.CENTER);
//Initialize the grid
for(int row = 0; row<=3;)
{
for (int col = 0; col<=3;)
{
JLabel lbl = new JLabel();
grid[row][col] = lbl;
grid[row][col].addMouseListener(this);
grid[row][col].setOpaque(true);
grid[row][col].setBackground(Color.white);
grid[row][col].setFont(new Font("Helvetica", Font.BOLD, 39));
p.add(grid[row][col]);
}
}
}
@Override
public void actionPerformed(ActionEvent ae)
{

@Override

你在問什麼,我不清楚 –
這顯然是家庭作業的幫助,而且你沒有付出努力。 –
@ChristopherSchneider我不想把整個代碼放進去,因爲它太長了,但這裏是我真正擁有的東西 – dude546546575
