我正在尝试打印迷宫。我是Java Swing图形的新手，我最初的想法是将每个单元格的JFrame个组件添加到CurrPos。运行此代码时，我得到垃圾结果。
有什么办法可以最小化这段代码，以便打印所有面板？请注意，Wall，Unvisited，Visited和JFrame是painComponent的子类，它们实现import java.util.ArrayList;
import java.util.List;
import javax.swing.JFrame;
import javax.swing.JPanel;
public class DrawMaze {
public final int WIDTH = 500;
public final int HEIGHT = 500;
JFrame frame;
public void initializeMaze(){
frame = new JFrame("Maze");
frame.getContentPane().setLayout(null);
frame.setSize(WIDTH, HEIGHT);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
public void drawMaze(String[][] maze, int[] currPosArray) {
//frame.removeAll();
addMazeContentsToList(maze, currPosArray);
frame.setVisible(true);
}
private void addMazeContentsToList(String[][] maze, int[] currPosArray) {
for (int i = 0; i<7; i++){
for (int j = 0; j<9; j++){
if ((i%2 == 1 && j%2 == 0) ||(i%2 == 0 && j%2 == 1) ){
Wall wall = drawWall(i, j);
frame.add(wall);
wall.repaint();
}
else if (i%2 ==0 && j%2 ==0){
if (i==currPosArray[0] && j==currPosArray[1]){
CurrPos currPos = drawCurrPos(i/2, j/2);
frame.add(currPos);
currPos.repaint();
}
else{
if (maze[i][j].equals("Unexplored")){
Unvisited unvisited = drawUnvisited(i/2,j/2);
frame.add(unvisited);
unvisited.repaint();
}
else{
Visited visited = drawVisited(i/2,j/2);
frame.add(visited);
visited.repaint();
}
}
}
}
}
}
private Visited drawVisited(int i, int j) {
int x = (int) Math.floor((i/4.0)*WIDTH);
int y = (int) Math.floor((j/5.0)*HEIGHT);
int width = (int) Math.floor(WIDTH/4.0);
int height = (int) Math.floor(HEIGHT/5.0);
return new Visited(x, y, width, height);
}
private Unvisited drawUnvisited(int i, int j) {
int x = (int) Math.floor((i/4.0)*WIDTH);
int y = (int) Math.floor((j/5.0)*HEIGHT);
int width = (int) Math.floor(WIDTH/4.0);
int height = (int) Math.floor(HEIGHT/5.0);
//System.out.println(x);
//System.out.println(y);
System.out.println(width);
System.out.println(height);
return new Unvisited(x, y, width, height);
}
private CurrPos drawCurrPos(int i, int j) {
int x = (int) Math.floor((i/4.0)*WIDTH);
int y = (int) Math.floor((j/5.0)*HEIGHT);
int width = (int) Math.floor(WIDTH/4.0);
int height = (int) Math.floor(HEIGHT/5.0);
return new CurrPos(x, y, width, height);
}
private Wall drawWall(int i, int j) {
//vertical wall
if (i%2 ==1){
int relativeX = (i+1)/2;
int relativeY = j/2;
int width = (int) Math.floor((1/4.0)*WIDTH*(0.2));
int height = (int) Math.floor((1/5.0)*HEIGHT);
int x = (int) Math.floor(((relativeX/4.0)*WIDTH - width*0.5));
int y = (int) (Math.floor((relativeY/5.0)*HEIGHT));
return new Wall(x, y, width, height);
}
//horizontal wall
else{
int relativeX = i/2;
int relativeY = (j+2)/2;
int width = (int) Math.floor((1/4.0)*WIDTH);
int height = (int) Math.floor((1/5.0)*HEIGHT*(0.2));
int x = (int) (Math.floor((relativeY/4.0)*WIDTH));
int y = (int) Math.floor(((relativeX/5.0)*HEIGHT - height*0.5));
return new Wall(x, y, width, height);
}
}
}
方法。
以下是代码：
public static function tzList()
{
$tzMap = array();
$zones = \DateTimeZone::listIdentifiers();
foreach ($zones as $zone) {
$tz = new \DateTimeZone($zone);
$now = new \DateTime("utc", $tz);
$diffInSeconds = $tz->getOffset($now);
$hours = floor($diffInSeconds / 3600);
$minutes = floor(($diffInSeconds % 3600) / 60);
$tzMap[$zone] = sprintf("%+d", $hours) . ":" . sprintf("%02d", $minutes);
}
return $tzMap;
}
