Initialization with inheritance

// The full process of initialization.
class Insect {
  int i = 9;
  int j;
  Insect() {
    prt("i = " + i + ", j = " + j);
    j = 39;
  static int x1 = 
    prt("static Insect.x1 initialized");
  static int prt(String s) {
    return 47;
public class Beetle extends Insect {
  int k = prt("Beetle.k initialized");
  Beetle() {
    prt("k = " + k);
    prt("j = " + j);
  static int x2 =
    prt("static Beetle.x2 initialized");
  static int prt(String s) {
    return 63;
  public static void main(String[] args) {
    prt("Beetle constructor");
    Beetle b = new Beetle();
} ///:~ 

The output for this program is:

static Insect.x initialized
static Beetle.x initialized
Beetle constructor
i = 9, j = 0
Beetle.k initialized
k = 63
j = 39
