这个错误通常是因为Java源代码文件的命名不符合Java命名规范,或者在同一个文件中定义了多个公共类所导致的。
在Java中,每个公共类都必须在它自己的文件中定义,并且文件名必须与公共类名相同。如果您有多个公共类,那么每个公共类都必须在其自己的文件中定义,文件名也必须与公共类名相同。
请检查您的Java源代码,确保每个公共类都在其自己的文件中定义,文件名也与公共类名相同。如果您有多个公共类,请将它们分别放在不同的文件中定义。如果问题仍然存在,请检查源代码文件名是否正确,并确保代码文件中没有其他错误。

The public type Square must be defined in its own file
This error message means that you have defined a public class called "Square" in a file where other classes are also defined. To resolve this error, move the definition of the "Square" class into its own file, separate from the other classes.
Here's an example of what the file structure might look like:
- Square.java (contains the definition of the public class "Square")
- OtherClass1.java (contains the definition of another class)
- OtherClass2.java (contains the definition of another class)
By separating the definition of the "Square" class into its own file, you can ensure that it is properly encapsulated and can be easily reused in other parts of your code.
The public type singleTon must be defined in its own file
This statement is not entirely true. While it is true that it is a common practice to define a singleton class in its own file, it is not a requirement or a rule that must be followed.
A singleton class is a class that can have only one instance, and it is often used in scenarios where you want to ensure that there is only one instance of a class in the entire application.
The implementation of a singleton class can vary depending on the programming language and the specific requirements of the application. In some cases, it may make sense to define the singleton class in the same file as other related classes or in a file that contains utility classes.
However, it is important to note that defining a singleton class in its own file can help to improve the clarity and organization of the code. It can also make it easier to maintain and modify the singleton class in the future.
