private CellComponent label; public void setAIModeGreedyOrNot(boolean AIModeGreedyOrNot) { this.AIModeGreedyOrNot = AIModeGreedyOrNot; } public void setAIModeSmartOrNot(boolean AIModeSmartOrNot){ this.AIModeSmartOrNot = AIModeSmartOrNot; } public GameController(ChessboardComponent view, Chessboard model, CellComponent cellComponent) { this.view = view; this.model = model; this.currentPlayer = PlayerColor.BLUE; this.label = cellComponent; model.currentPlayer = this.currentPlayer; view.registerController(this); //initialize(); view.initiateChessComponent(model); view.repaint(); //System.out.println(currentPlayer + "这个restart到底是怎么回事");//测试restart }怎么对label进行修改

要修改`label`的值,可以提供一个公共的setter方法,例如:
```java
public void setLabel(CellComponent label) {
this.label = label;
}
```
然后在需要修改`label`的地方,调用该方法即可:
```java
CellComponent newLabel = new CellComponent();
// 设置新的label属性值
controller.setLabel(newLabel);
```
注意,该方法必须在`GameController`实例化之后才能被调用,否则会抛出`NullPointerException`异常。

class Gezi { private int x; private int y; private boolean filled; private boolean searched; private boolean colored; private boolean go; private boolean start; private boolean end; public boolean isStart() { return start; } public void setStart(boolean start) { this.start = start; } public boolean isEnd() { return end; } public void setEnd(boolean end) { this.end = end; } public boolean isGo() { return go; } public void setGo(boolean go) { this.go = go; } public boolean isColored() { return colored; } public void setColored(boolean colored) { this.colored = colored; } public int getX() { return x; } public void setX(int x) { this.x = x; } public int getY() { return y; } public void setY(int y) { this.y = y; } public boolean isFilled() { return filled; } public void setFilled(boolean filled) { this.filled = filled; } public boolean isSearched() { return searched; } public void setSearched(boolean searched) { this.searched = searched; } public Gezi() { } public Gezi(int x,int y,boolean filled,boolean searched) { this.filled = filled; this.x = x; this.y = y; this.searched = searched; } }
这是一个Gezi类,它定义了8个私有属性和8个公共方法。其中,x和y表示该Gezi对象在平面上的位置,filled和colored是布尔类型的属性,表示该Gezi对象是否被填充和是否被染色,searched和go也是布尔类型的属性,表示该Gezi对象是否被访问过和是否可以通过。start和end也是布尔类型的属性,表示该Gezi对象是否为起点和终点。这个类可以用于表示平面上的一个格子,并记录格子是否被填充、染色、访问过,以及是否可以通过和是否为起点或终点。
public void Play(boolean isStarting) { if (isStarting==true&&mPlayer!=null&&mPlayer.isPlaying()==false) { mPlayer.start(); } }
) {System.out.println("Let's play!");} else {System.out.println("Game over!");}这个代码片段有什么问题?可以运行吗?如果有问题,请指出并改正。
这个代码片段可以运行,但是if语句中的"isStarting==true"部分可以简化为"isStarting",因为"isStarting"已经是布尔类型,不需要再与"true"进行比较。所以改正后的代码如下:
public void Play(boolean isStarting) {
if (isStarting) {
System.out.println("Let's play!");
} else {
System.out.println("Game over!");
}
}
