令牌上的java Sytnax错误，构造位置错误

Question

我在做一个计算机科学的作业，我有几个错误。我不得不上传代码，因为我无法让它在Stackoverflow上工作。这是链接：http://txt.do/tqmh

以下是错误：

请帮忙

Answer 1

正如已经发布的，在主方法中有静态方法，这是根本错误的。你不能在一个方法中有一个方法——除非它在匿名类中（但我们不要讨论这个）。因此，首先要删除main(String[] args).中的所有方法

例如，你应该

public static void main(String[] args) {
    page1();
    page2();
    page3();
}
// this is now outside of your main method but inside your class 
public static void page1() {

}
public static void page2() {

} 
//etc.

另外，如果您想将参数传递给一个方法，我可以看到您需要为if语句传递参数，您可以通过这样做，即

public static void main(String[] args) {
    // this is just example..!!

    String letter = "A";
    page1(letter);

    // what the above code will do, is pass a letter "A" as an argument to this "page1"
    // method and as a result you will be able to use this letter inside the method

}
public static void page1(String letter) {
    System.out.println(letter); // this will print letter "A"
}

我不明白您想做什么，但此代码应该可以工作：

import java.util.Scanner;
public class CYOA_Om_Malhar 
{
    public static void main(String[]args) 
    {
        Scanner in = new Scanner(System.in);
        String choice = "";
        Introduction();

        //Instructions
        System.out.println("Please type 'A' or 'B' to choose an option: ");
        while(!choice.equalsIgnoreCase("A") && !choice.equalsIgnoreCase("B") ){
            choice = in.nextLine();
        }

        page1(choice);
        page2(choice);
        page3(choice);
        page4(choice);
        page5(choice);
        page6(choice);
        page7();


    }

        System.out.println("You reach over to pick it up, and you realize that it's a wallet full of cash. ");
        System.out.println("You take it home to your rat infested apartment. ");
        System.out.println("You then start counting the money as soon as you sit on the squeaky chair of yours. ");
