Hi,

I found that VarWizard created a new code which is not semantic-equivalent to the original code for Nullable annotation in Java. For reproducing the bug, please use the following example

"""
import javax.annotation.Nullable;

public class NullableSample {
    
    public static void main(String[] args) {
        String nullableString = getNullableString(null);
        
        if (nullableString != null) {
            System.out.println(nullableString.toUpperCase());
        } else {
            System.out.println("Nullable string is null.");
        }
    }
    
    private static String getNullableString(@Nullable String nullableString) {
        boolean condition = true; // Simulating some condition
        
        if (condition) {
            return "Hello, World!";
        } else {
            return null;
        }
    }
}
"""

In the new code provided by VarWizard, Nullable annotation is replaced by NotNull annotations. This replacement not only changes the semantics of the code but also creates a critical bug in the new code.

I think the bug may come from your parser which wrongly identified @nullable as a variable name.

Hi,

When installing VarWizard using pip install varwizard, it did not install scipy library automatically. While the missing library can manually be installed, it is great to be fixed.

Thanks.
