为什么会出现语法错误[已关闭]

Question

// The "Summative" class.

// Purpose: To create a program as part of the summative
import java.awt.*;
import hsa.Console;

public class Summative

    static Console c;           // The output console

    public static void main (String[] args)
    {
        c = new Console ();
        
        // Title Page 
        
        c.setColor (Color.orange);
        c.fillRect (0, 0, 2000, 900);
        c.drawRect (0, 0, 2000, 900);
        
        c.setColor (Color.white);
        Font times = new Font ("Times", Font.BOLD, 50);
        c.setFont(times);
        c.drawString ("Summative", 180, 50);
        
        Font tahoma = new Font ("Tahoma", Font.BOLD, 20);
        c.setFont(tahoma);
        
        c.getChar ();
        c.clear ();       
       
        int choice;
       
        {
        c.drawString ("\t\t 1.Count Vowels", 0, 250);
        c.drawString ("\t\t 2.One Dimensional Array Task", 0, 300);
        c.drawString ("\t\t 3.Graphical animation", 0, 350);

        choice = c.readInt ();
        if ((choice < 1) || (choice > 6))
        c.println ("Invalid ... enter 1-6 only");
        }
        while ((choice < 1) || (choice > 6));
        switch (choice)

        c.println ("What word would you like to enter?");
   
    String word = c.readString ();
   
    int count1 = 0;
      for (int num = 0 ; num < word.length () ; num++)
      {
        char numbers = word.charAt (num);

      }

     if (count1 == 0)
  {
     
    int count = 0;
      for (int num = 0 ; num < word.length () ; num++)
      {

        {
          count++;
        }
      }
      c.println (" There are " + count + " vowels");
     
      if (count == 0)
     
      {
      c.println("There are no vowels in the word");
      }
    
  } 

这是我的考试项目，当我运行程序时似乎存在语法错误。错误发生在第 8 行和第 9 行，即类所在行和类下方行。我在这里做的是一个菜单，这些就是选项。我使用“准备编程”来创建程序。

Answer 1

你失踪了

{

:

public class Summative {

    static Console c;

编辑

正如 @ccheneson 所提到的，您的类定义的结束

}

似乎也丢失了。

你应该看看你的代码缩进，一开始似乎很好，但后来就失败了。通过适当的缩进，您可以轻松发现这些错误，因为几乎所有缩进块都必须用

{

和

}

括起来。
