Java arrays
An array is a set of data that has the same data type. Java supports multiple arrays, each base cell of a one-dimensional array is data of the basic data type, and the two-dimensional array is a one-dimensional array of one-dimensional
A one-dimensional array is essentially a set of linear sets of the same type that can be applied when the program needs to process a set of data or pass data.Create a one-dimensional array: An array as an object allows memory to be allocated using
