How are Java class names and method names distinguished?

In Java, the distinction between class names and method names is implemented through the naming conventions of identifiers. Here are some common naming conventions:

1. Class names should start with a capital letter and use camel case naming convention. For example, MyClass.
2. Method names should start with a lowercase letter and use camel case naming convention. For example: myMethod.
3. To better differentiate class names and method names, you can add a pair of parentheses after the class name. For example, the myMethod method in the MyClass class can be named myMethod().

In summary, the distinction between class names and method names is mainly achieved through the use of uppercase letters for class names and lowercase letters for method names, following certain naming conventions. Class names start with a capital letter, while method names start with a lowercase letter, and usually include a pair of parentheses at the end.
