java - 语法错误，插入“VariableDeclarators”以完成LocalVariableDeclaration的发生

public class Water {
    private Graphic graphic;
    private float speed;
    private float distanceTraveled;

    public Water(float x, float y, float direction)
    {
        speed = 0.7f;

        graphic = new Graphic();
        graphic.setType("WATER");

        graphic.setX(x);
        graphic.setY(y);

        direction = graphic.getDirection(); //direction from Hero as water is fired
    }
    public Water update(int time)
    {
        graphic.draw();
        return Water.this;
        distanceTraveled; // this is where the error occured...
    }
}

当我尝试调用distanceTraveled时，出现以下错误:

最佳答案

要使语法错误消失并为distanceTraveled分配值，请修改public Water update(int time)方法，如下所示:

public Water update(int time) {
    graphic.draw();
    distanceTraveled = 1; // assign a value before returning
    return Water.this;
}

也许您应该阅读一些有关Java的知识并进行一些教程，因为这是非常基础的内容(至少在我没有弄错的情况下)。
