2d配列と関数paintcomponentを使用して10 x 10のグリッドを作成する私の学校プロジェクト用のコードを書きました。PaintComponentはタイルをペイントしないか、文字列を描画しません
私の問題は、グリッドが表示されないか、文字列が表示されないということです。 （コンパイラがすべてのエラーを表示しません。）
は、ここに私のコードです：事前に
public class Tile extends Board {
public Tile() {
}
final private static int CELL_WIDTH = 50;
final private static int CELL_HEIGHT = 50;
final private static int BOARD_X_OFFSET = 25;
final private static int BOARD_Y_OFFSET = 25;
private int x;
private int y;
private int getScreenX(int x, int y) {
return BOARD_X_OFFSET + x * CELL_WIDTH;
}
private int getScreenY(int x, int y) {
return BOARD_Y_OFFSET + y * CELL_HEIGHT;
}
public Tile(int x, int y) {
this.x = x;
this.y = y;
}
@Override
public void paintComponent(Graphics g) {
g.setColor(Color.BLACK);
g.drawRect(
getScreenX(x, y),
getScreenY(x, y),
CELL_WIDTH,
CELL_HEIGHT);
}
}
おかげ
Board.java

Player hero;
@Override

int i = 0;
int positionX = 50;
int positionY = 50;
for (int y = 0; y < map.length; y++) {
for (int x = 0; x < map.length; x++) {
new Tile(x, y).paintComponent(g);
g.drawString(gameElements[i], positionY, positionX);
map[y][x] = gameElements[i];
positionY += 50;
System.out.print("[" + map[y][x] + "]");
i++;
}
positionY = 50;
positionX += 50;
System.out.println();
paintComponentExecuted = true;
