Why is my code showing the error - 'integer number too large'; although i had already declared the argument type as long?

Question

class Fox{

    long phone_number;

    public Fox(long num){
        this.phone_number = num;
    }
}

public class Box{
    public static void main(String[] args){
        Fox object = new Fox(88888888888888888);
        System.out.println(object.phone_number);
    }

}

Answer 1

88888888888888888 is an int literal (that's the default type for integral literals when no suffix is specified), and it's too large for an int. Use 88888888888888888L or 88888888888888888l for a long literal.
