first - constructor name should be the same as class name.
second - you can initialize array in shorter form.
Code:
public class Abc
{
public long a;
public String b;
public long c;
public Abc(long d, String e, long f)
{
a = d;
b = e;
c = f;
}
}
final class Hij
{
static Abc[] item1 = new Abc[]{new Abc(0, "Kxxx322;opot", 24315),
new Abc(1, "Podciep", 523427),
new Abc(2, "Promocja", 25342537)};
}
