1、使用Arrays的sort()方法排序 2、使用Arrays的binarySearch(Object[] a, Object key)方法查找元素 3、使用Arrays的copyOfRange(int[] original, int from, int to)方法拷贝元素 将数组中指定范围的元素复制到一个新的数组中,该方法中参数original表示被复制的数组,from表示被复制元素的初始索引(包括),to表示被...
int[] arr = {1,3,4,5,6};intindex=Arrays.binarySearch(arr,4);//index的值为2intindex=Arrays.binarySearch(arr,2);//index2的值为-1 大数据运算 java中long型为最大整数类型,对于超过long型的数据如何去表示呢.在Java的世界中,超过long型的整数已经不能被称为整数了, 它们被封装成BigInteger对象.在B...

Java中的Collection和List是两种常用的数据结构,它们之间有一些区别。 List是一种有序的集合,它继承自Collection接口。List中的元素可以重复,并且可以通过索引来访问。List中的元素可以被重复添加,但是它们在List中的位置是不同的。List中的元素可以被随机访问,因此它们可以被用于实现队列和栈等数据结构。 Collection是一...
