Is it possible to take length of array from user then initialize array of that length

Question

Array have a specific length, is it possible to create the array according to the user

I always initialize array of 100 elements, but what happened if user want to enter more than 100 elements, then I have to change value from 100 to more than hundred

Answer 1

Yes abcurce you can just take variable and initialize it and give a message of please enter the length
than put the variable to the array container.

eg:-
Scanner sc=new Scanner (System.in);
System.out.print("Enter the length of array");
int a=sc.nextInt();
int b[]=new int[a]; // putting the initialize value.

and start the process.
