请问a,b,c的答案为？public class M9012 { public static void main(String[] args) { // TODO Auto-generated method stub SubSubClass x = new SubSubClass(100,110,200); x.show(); }} class SuperClass{ int a,b; SuperClass(int aa,int bb){ a=aa; b=bb; } void show() { System.out.println("a="+a+" b="+b); } } class SubClass extends SuperClass{ int c; SubClass(int aa,int bb,int cc){ super(aa,bb); c=cc; } } class SubSubClass extends SubClass{ int a; SubSubClass(int aa,int bb,int cc){ super (aa,bb,cc); a=aa+bb+cc; } void show() { System.out.println("a="+a+" b="+b+" c="+c); } }
