Find their basic knowledge is not solid enough, slowly review!Array creation:Mode one: type[] Variable name = new type[element number]; -such as: int[] a = new int[10];Mode two: type variable name [] = new type[element number]; -such as: int a[] =

An array is a collection of ordered data. Elements in an array may not belong to the same data type. Using a uniform array name and subscript to uniquely determine an element in an array, changing one of the elements does not affect other elements.

In Java, you can use the copy statement "A=b" to pass values to the basic type of data, but if a and B are two arrays of the same type, copying is equivalent to passing a reference to an array variable to another array, and if an array changes,

Assigns the same value to all elements of the array:Boolean[] Resarray=new boolean[100]; Arrays.fill (Resarray, true);Copying between arrays:System.arraycopy (object src, int srcpos, object DST, int dstpos, int length)src: source array; Srcpos: The
