How to scan a user's new input using a scanner in a while loop?

Question

I have developed a character sorter and I want to prompt the user to enter a new string every time after the string is sorted. The issue I am having is that the scanner keeps scanning the first input of the user. If I use scanner.next(), it does not counts the white space at the end of the input, which is not the solution.

This is the start of the while loop. Once the code finishes, it starts again from "inputText".

    inputText:
    while(keepSorting){

        System.out.print("Please input the string to be sorted: " );
        c.settingInput(s.nextLine());
        System.out.println(" ");
        int option;

        more code
        .... }

nextLine will give you the next line. Not sure what you mean. — Scary Wombat

Do you want to stay inside the while loop? If so, there must be some line of code that redirects to inputText: — Vaibhav

If you want help debugging your code then you need to post a minimal reproducible example. — Abra

Scanner sc= new Scanner(System.in); 
while(true){
String a = sc.nextLine();
System.out.println(a);

}

If you want to know more about Scanner then read this documentation.
