使用InventoryPart 2程序的Java代码，不知道我做错了什么？

I get the following error code:

我收到以下错误代码:

C:\Documents and Settings\AdminUser\My Documents\InventoryPart2.java:83: class, interface, or enum expected
import java.util.*;

As @Greg and @EboMike stated, make sure you split your code in two files: Television.java and InventoryPart2.java.

正如@Greg和@EboMike所述,请确保将代码拆分为两个文件:Television.java和InventoryPart2.java。

Then, you have a typo here:

然后,你有一个拼写错误:

for (int i = 0; i < 5; i++){ //output total inventory value
    System.out.printf("Total Value of Inventory is: \t$%.2f\n", + myTelevision[i].getCalculateInventory());
    System.out.println();
}

It's myTelevision s[i].

这是我的电视剧[i]。

If you fix what I'm telling you, your code runs fine... no worries. :)

如果你修复我告诉你的内容,你的代码运行正常......不用担心。 :)

EDIT:

I shouldn't be checking your code's logic here but if the last cycle is meant to compute the total inventory sum it should be something like this:

我不应该在这里检查你的代码的逻辑,但如果最后一个周期是为了计算总库存总和,它应该是这样的:

    //output total inventory value
    double total = 0.0;
    for (int i = 0; i < 5; i++){ 
        total +=  myTelevisions[i].getCalculateInventory();            
    }
    System.out.printf("Total Value of Inventory is: \t$%.2f\n", total);

Is this all the same file? The import statement needs to go to the top.

这是同一个文件吗? import语句需要转到顶部。

The error message clearly shows you which line is causing a problem.

错误消息清楚地显示哪条线导致问题。

#3

You've got a line

你有一条线

import java.util.*;

in the middle of your file. Java requires that import declarations go at the top of the file, before any class, interface, or enum declarations.

在您的文件中间。 Java要求在任何类,接口或枚举声明之前,导入声明位于文件的顶部。

#4

Two problems jump out at me:

两个问题突然出现在我面前:

As the error message says, you have an import statement out of place. Imports go at the top, after the package declaration and before the class declaration.

正如错误消息所示,您有一个不合适的import语句。在包声明之后和类声明之前,导入位于顶部。
Assuming that the code you posted is in fact all in one file, you need to separate it into two files. You can't have two public classes in one .java file.

假设您发布的代码实际上都在一个文件中,您需要将其分成两个文件。您不能在一个.java文件中拥有两个公共类。
