What will be the result of attempting to compile and run a Java class that contains a variable declared as int public;?

A compilation error will occur due to using a reserved keyword as a variable name.
The code will compile and run without errors.
The code will compile but result in a runtime error.
The code will compile but will produce a warning message.

In Java, "public" is a reserved keyword used to declare access modifiers. Using it as a variable name will result in a compilation error since you cannot use reserved keywords as variable names. This is a fundamental rule in Java's syntax. Attempting to compile and run such code will indeed lead to a compilation error.
