Java行动连线游戏：静态方法调用警告及Linux运行环境咨询

Hey there! That IDE warning is pointing out a common Java best practice misstep—you're calling a static method using an instance of the Board class, which isn't the standard way to access static members. Let's break down two clear fixes depending on how your Board class is designed.

Option 1: Call the static method directly via the Board class (Recommended for static methods) #

Since newBoard(int) is a static method, it belongs to the Board class itself, not any individual instance of the class. So you should call it using the class name instead of an object reference:

public class Loa{
    public static void main(String[] args) {
        int boardSize = Integer.parseInt(args[0]);
        // Call static method directly using the Board class name
        Board.newBoard(boardSize);
    }
}

This gets rid of the warning and follows Java's standard conventions for static method access. Use this approach if newBoard is meant to handle class-wide operations (like initializing a static board array shared across all Board instances).

Option 2: Convert newBoard to an instance method (If it's meant to initialize a specific board) #

If newBoard is supposed to set up the state for a specific Board object (i.e., it initializes instance variables unique to that board), remove the static modifier from the method in your Board class:

// Inside your Board class, update the method to remove static
public void newBoard(int boardSize) {
    // Your existing logic to initialize this instance's board array
}

With this change, your original Loa code will work without warnings, because newBoard is now an instance method meant to be called on a specific Board object (like playBoard). This makes sense if each Board instance has its own unique game board state.
