No, they're not.

Code:

public class Example1 {
    public static void main(String[] args) {
        Example2 e2 = new Example2();
        e2.var = 56; // 1
        e2.setVar(56); // 2
    }
}

public class Example2 {
    public int var;
    
    public void setVar(int v) {
        var = v;
    }
}

1 and 2 both work.

Is this what you mean or...?
