// other functions ... } 5. 其他功能方法 1. write/readObject 前面在介绍数据域的时候我就有标注 elementData 是一个 transition 的变量也就是在自动序列化的时候会忽略这个字段。 然后我们又在源码中找到到了write/readObject方法,这两个方法是用来序列化elementData中的每一个元素,也就是手动的对这个字段进行...
Lots of logical errors and a few mistakes of style. First you basically skipped all nonprime numbers, and primes are not abundant. You are really not using the prime-ness anyway so it can be removed. In Java we declare the types as interface, when possible (in anticipation of possible fu...
