如题:
import static net.mindview.util.Print.*;
class Insect {
private int i = 9;
protected int j;
Insect() {
print("i = " + i + ", j = " + j);
j = 39;
}
private static int x1 =
printInit("static Insect.x1 initialized");
static int printInit(String s) {
print(s);
return 47;
}
}
public class Beetle extends Insect {
private int k = printInit("Beetle.k initialized");
public Beetle() {
print("k = " + k);
print("j = " + j);
}
private static int x2 =
printInit("static Beetle.x2 initialized");
public static void main(String[] args) {
print("Beetle constructor");
Beetle b = new Beetle();
}
}
------解决方案--------------------
static Insect.x1 initialized
static Beetle.x2 initialized
i=9,j=0
Beetle.k initialized
k=47,j=0
