多次使用来自扫描仪的用户输入？

Question

I am trying to use a user-entered number from the scanner in my code in multiple places. Below the line should be the same user-entered number as the first. Is this possible?

Scanner inputHere = new Scanner(system.in);
System.out.println("Please select me");
String inputHereOne = inputHere.nextLine();
System.out.println("----------------------------------");

Answer 1

Yes, it's possible. Use the value stored in inputHereOne . No need to call inputHere.nextLine() until you actually need the next line of input. Like so:

System.out.println(inputHereOne);
System.out.println(inputHereOne);

This will print inputHereOne , twice.
