5,继承时候类的执行顺序问题,一般都是选择题,问你将会打印出什么?
答:父类：
package test;
public class FatherClass
{
public FatherClass()
{
System.out.println("FatherClass Create";
}
}
子类:
package test;
import test.FatherClass;
public class ChildClass extends FatherClass
{
public ChildClass()
{
System.out.println("ChildClass Create";
}
public static void main(String[] args)
{
FatherClass fc = new FatherClass();
ChildClass cc = new ChildClass();
}
}
输出结果：
C:>java test.ChildClass
FatherClass Create
FatherClass Create
ChildClass Create
