and:
22. Test t = new Test();
23. // insert code here
Which two will compile without errors when inserted at line 23?
(Choose two.)
A. Object x = t.findLarger(123, “456”);
B. int x = t.findLarger(123, new Double(456));
C. int x = t.findLarger(123, new Integer(456));
D. int x = (int) t.findLarger(new Double(123), new Double(456));

Object x = t.findLarger(123, "456");-----> 类型转换异常
int x = t.findLarger(123, new Double(456)); ;----->   编译失败
int x = t.findLarger(123, new Integer(456)); ;-----> 456
int x = (int) t.findLarger(new Double(123), new Double(456));;-----> 编译失败
