为什么内置JComponent方法抛出'无法找到符号'?

除了getInputMap之外,关于此代码的所有内容都可以正常工作。我看了一遍,找不到原因。在程序中,它说无法找到符号。如果它是JComponent的内置方法,怎么会这样呢?

package dungeon_adventure;


public class Dungeon_Adventure {
public static Dungeon_Adventure_Display Dungeon_Display;

public static void main(String[] args) {

    game_engine();
}

private static void game_engine() {
    String welcome_text = "Welcome to Dungeon Adventure\nStay a while!\nStay 
    forever!";
    Dungeon_Display = new Dungeon_Adventure_Display();
    Dungeon_Display.getInputMap().put("userInput", "myAction");
    Dungeon_Display.change_image("square_1.jpg");
    Dungeon_Display.add_text(welcome_text);
}

}
