Problem with creating a new object

Question

It's my stupid simple code:
class Readers {
     int i, a;
public     Readers(int i, int a){
public static void main(String[] args) {
Readers[] d = new Readers[5];
d[4] = new Readers(2,2);
System.out.println(+d[4].i);
Why do I get the answer 0, instead of 2?

Answer 1

See the comments in your code:
class Readers {
    int i, a; // the global variables 'i' and 'a' are both initialized with zero
    public Readers(int i, int a){
        // the local values 'i' and 'a' are lost: you don't do anything with them!
    public static void main(String[] args) {
        Readers[] d = new Readers[5];
        d[4] = new Readers(2,2);
        System.out.println(d[4].i);
} // note that you don't need semi-colons after a '}'
