現(xiàn)有:
class Cat {
Cat(int c) { System.out.print("cat" + c + " "); }
}
class SubCat extends Cat {
SubCat(int c) { super(5); System.out.print("cable "); }
SubCat() { this(4); }
public static void main(String [] args) {
SubCat s = new SubCat();
}
}
結(jié)果為:()
A.cat5
B.cable
C.cable cat5
D.cat5 cable
