一维数组(one-dimensional array)实质上是一组相同类型数据的线性集合,是数组中最简单的一种数组。 数组是引用数据类型,引用数据类型在使用之前一定要做两件事情:声明和初始化。所以本文将重点介绍一维数组的创建、初始化和使用。 创建一维数组 为了在程序中使用一个数组,必须声明一个引用该数组的变量,并指明整个变量...
Concept: Each element in an array is a one-dimensional array, and the array is called a two-dimensional array.静态初始化：Static initialization:动态初始化：Dynamic initialization:注：其中列个数可以省略不写，因为Java中的二维数组存在不规则矩阵这样的数组，因此写了也没有多大意义。Note: The number of...

one-dimensional array is faster than a two-dimensional array. Use the faster switch bytecode. Use private and static methods, and final classes, to encourage inlining by the compiler. Reuse objects. Local variables are the faster than instance variables, which are in turn faster than array elem...
/**(Sales Commissions) Use a one-dimensional array to solve the following problem: A company pays its salespeople on a commission basis. The salespeople receive $200 per week plus 9% of their gross sales for that week. For example, a salesperson who grosses $5,000 in sales in a week ...
In computer science, the maximum sum subarray problem is the task of finding a contiguous subarray with the largest sum, within a given one-dimensional array A[1...n] of numbers. Formally, the task is to find indices and with, such that the sum is as large as possible. ...

It works on an N-dimensional array object and provides basic mathematical functionality such as size, shape, mean, standard deviation, minimum, maximum as well as some more complex functions such as linear algebraic functions and Fourier transform. You will learn more about these as we move ...
