Can we have multiple classes in the same java file?

No, you cannot have multiple classes in the same Java file. Each Java file can contain only one public class. If you try to declare more than one public class in a single Java file, you will get a compiler error.

Why?

This is because Java is a strongly typed language, which means that each class must be defined in its own file. This rule helps to keep your code organized and makes it easier to debug and maintain.

If you need to define multiple classes in the same file, you can do so by making them all non-public. Non-public classes are only accessible within the same file. For example:

class A { }
class B { }
class C { }

In the above example, all three classes are only accessible within the same file. If you try to access them from another file, you will get a compiler error.

So, in summary, you cannot have multiple public classes in the same Java file but you can have multiple non-public classes. This rule helps to keep your code organized and makes it easier to debug and maintain.

1. Can we have multiple classes in one java file?

No, you cannot have multiple classes in the same Java file. Each Java file can contain only one public class. If you try to declare more than one public class in a single Java file, you will get a compiler error.

2. How many classes can a Java file contain?

A Java file can contain any number of non-public classes, but it can contain only one public class. If you try to declare more than one public class in a single Java file, you will get a compiler error.

3. What is the purpose of multiple classes in one java file?

The purpose of having multiple classes in one java file is to keep your code organized and make it easier to debug and maintain. This rule helps to keep your code organized and makes it easier to debug and maintain.

4. How do I create multiple classes in one java file?

You cannot have multiple classes in the same Java file. Each Java file can contain only one public class. If you try to declare more than one public class in a single Java file, you will get a compiler error.

5. What are the benefits of multiple classes in one java file?
