【问题描述】:
应该是一个简单的修复,但我想知道如何使用在 main.js 中创建的对象。我试着说人类 h;在 main (或任何其他方法)之外,所以我可以在其他方法中调用它,但是因为我使用的是静态方法,所以我不能使用 h.现在有了这段代码,java 告诉我找不到 h(在人工滚动方法中)。
import java.util.Scanner;
class Main
{
// static Human h;
public static void main(String[] args)
{
Scanner scan = new Scanner(System.in);
Computer c = new Computer();
Human h = new Human();
System.out.println("Let's play PIG");
System.out.println("What is your name");
String name = scan.nextLine();
System.out.println("Hello" + " " + name + " " + "you can go first");
startGame(h, name);
}
public static void startGame(Human h, String name)
{
Scanner scan = new Scanner(System.in);
System.out.println("Press r to start your roll");
String rresponse = scan.nextLine();
if(!rresponse.equalsIgnoreCase("R"))
{
System.out.println("Try again");
startGame(h, name);
}
if(rresponse.equalsIgnoreCase("R"))
{
System.out.println("You pressed r, lets roll");
humanRoll(h, name);
}
}
public static void humanRoll(Human h, String name)
{
if(h.getRollNumh()==1)
{
System.out.println(name + " " + "you got a " + h.getRollNumh());
System.out.println("You got a score of" + h.getHumanTurnScore() + "this turn");
System.out.println("Here is your current overall score" + h.getHumanOverallScore());
System.out.println("Your rolled a one, now its the Computers' turn");
switchHuman();
}
}
}
如果您需要查看 Human 类以提供上下文,我可以快速响应并添加它,但它只是实例变量、默认构造函数、重载构造函数、访问器方法和 mutator 方法。
【问题讨论】:
-
您需要添加一个参数并将该对象作为参数传递。例如,
public static void humanRoll(Human h)。然后用humanRoll(h)调用它。
