Java 16-16 Keyboard input data to find the maximum value

Demand:
Keyboard input multiple data, enter 0 o'clock to get results, output the largest one
Analysis:
A: Create A Keyboard entry
B: Because the number of data is uncertain, receive with the collection
C: Put the keyboard input data into the set
D: Because we didn't learn the sort of collection, we had to turn the set into a group
Public object[] ToArray () returns an array that contains all the elements in this list, in the appropriate order (from first to last element).
Public <T> t[] ToArray (t[] a) returns an array containing all the elements in this list in the appropriate order (from first to last); The run-time type of the returned array is the run-time type of the specified array.
E: Sorting data for an array
F: Output index is length-1 that data
G: Print, I want to print out the acquired collection again
A: Create a method to stitch the array to a string
return type: String
Parameter list: Integer XX
B: Refer to this method when printing
