牛课网刷到一道题
public class Test { public static void main(String [] args){ System.out.println(new B().getValue()); } static class A{ protected int value; public A(int v) { setValue(v); } public void setValue(int value){ this.value = value; } public int getValue(){ try{ value++; return value; } catch(Exception e){ System.out.println(e.toString()); } finally { this.setValue(value); System.out.println(value); } return value; } } static class B extends A{ public B() { super(5); setValue(getValue() - 3); } public void setValue(int value){ super.setValue(2 * value); } } }
