I am writing this java program to find all the prime numbers up to num using the Sieve of Eratosthenes, but when I try to compile, it says I can't use a long var as an array index, and it expects an int var in its place. But I'll be working with large numbers, so I can't...
Java集合框架概述集合、数组都是对多个数据进行存储操作的结构,简称Java容器。使用Array存储对象方面具有一些弊端,而Java 集合就像一种容器,可以动态地把多个对象的引用放入容器中。数组在存储多个数据方面的特点:一旦初始化以后,其长度就确定了。 数组一旦定义好,其元素的类型也就确定了。我们也就只能操作指定类型的数据...
