How to use Java collection framework Arrays

Concept 1. Tool classes used to operate arrays contain static methods. 2. The included method is binary search, copies the specified array length, returns the string of the specified array content, and compares the two arrays to see if the depths of the two arrays are equal to each other, specifies the depth content (hash value) of the array, and compares the two arrays to see if If equal, replace all the contents in the array, return the hash value according to the contents of the array, and sort. Example //The elements in the array are all objects classArraysDemo{publicstaticvoidmain(String[]args){String[]arr={"abc","cc","kk
