可以的。
class Parent(){public Parent(){System.out.println(" parent 1");}public Parent(String n){System.out.println(" parent 2 "+n);}}class Child extends Parent(){public Parent(){super();System.out.println(" Child 1 ");}public Parent(String n){super(n);System.out.println(" Child 2 "+n);}public Parent(int n){System.out.println(" Child 3 "+n);}}
