Can there be multiple public classes in java?

no. In Java, there can only be one public class in a source file to prevent name conflicts, clarify program entry points, and maintain code organization.

Can there be multiple public classes in Java?

Answer: No

Explanation:

In Java, there can only be one in a source file public classes, so the compiler will not compile source files containing multiple public classes. The public class is the entry point in the file from which the Java Virtual Machine (JVM) begins executing the program.

Reason:

• Prevent name conflicts: Multiple public classes will cause name conflicts, because in Java, the name of the class Must be unique within the package scope.
• Clear program entry point: Having only one public class ensures that the program has a clear entry point, which is required for JVM execution.
• Keep your code organized: Organizing multiple classes into a single source file can make the code difficult to read and maintain.

Note:

• If you want to define multiple classes in a single source file, these classes must be nested classes or belong to different package.
• Even though these classes are not public classes, they can still access other classes in the same source file.
