8、。 5、一个Java类可以有多个父类。 6、子类的域和方法的数目一定大于等于父类的域和方法的数目。 7、System类不能实例化，即不能创建System类的对象。 8、接口里的方法必须全部都声明成abstract。 9、最终类不能派生子类，最终方法不能被重载。 10、设String对象s=”Hello ”，运行语句System.out.println(s.concat(“World!”);后String对象s的内容为”Hello world!”，所以语句输出为：Hello world!。 三、填空题（每空格2分，共20分）1、根据程序的构成和运行环境的不同，Java源程序分为两类：_程序和_程
