Cava modifiers

static

The static modifier defines class functions. Apply it to methods only — Cava does not support class variables. For more information, see Classes and objects.

Correct usage — static method:

class Example {
    static int main() {
        return 0;
    }
}

Incorrect usage — static variable:

Applying static to a variable causes a compilation error:

class Example {
    static int i; // Error: static variables are not supported.
    static int main() {
        return 0;
    }
}

ERROR cava.common.Diagnostics : benchmark/example.cava:1.15-2.16 [30001] static variable is not support:i

Access modifiers

Cava is syntactically compatible with these access modifiers:

• public

• protected

• private

• final

However, these modifiers do not affect the access to a class member. No matter which access modifier you use, all class members are publicly accessible regardless of which modifier you apply:

class Example {
    public double PI; // <==
    Example() {
        PI = 3.1415926;
    }
    static int main() {
        Example example = new Example();
        double a = example.PI;
        return 0;
    }
}

Because access modifiers have no effect in Cava, avoid using them to prevent confusion.
