如何阻止我的代码立即将整个地图写入终端？

Question

所以，我在Java中创建了一个二维数组映射，并且它编写了整个映射。这显然是非常滞后的

public static final int WIDTH = 1000;
public static final int HEIGHT = 1000;

public static String[][] map = new String[HEIGHT][WIDTH];

如何阻止它将所有内容写入终端，而是将其打印出来以进行优化？ 这是我的其余代码：

static int x = 0, y = 5;

public static void main(String[] args) {
    myScreen = new MyScreen(TerminalFacade.createTerminal());
    myScreen.startScreen();
    myScreen.drawText("Dungeon Tredge", 0, 0, Color.RED);
    myScreen.drawText("(C) 3 on a Java course", 0, 1, Color.YELLOW);
    myScreen.drawText("TO DO: displayMap, addTree, addRock, addRoom", 0, 2,
            Color.YELLOW);
    myScreen.displayMap(0, y);
    myScreen.refresh();

    while (true) {
        Key key = myScreen.readInput();
        if (key != null)
            handleInput(key.getCharacter());

        if (myScreen.resizePending()) {
            myScreen.displayMap(0, y);
            myScreen.refresh();
        }
