about java: get `String[].class` from `String.class`, what if `String.class` is a “runtime type”? [duplicate]

Answer 1

Another trick I found is using varargs on util method.

public static void main(String[] args) throws ClassNotFoundException {

    Class demo = Main.getArrayClass();
    System.out.println(demo);
}

static  Class getArrayClass(T... param){
    return param.getClass();
}
