I've always seen a lot of confusion between (usually) beginners on the Java language about the use of Scanner. As someone who got a bit of knowledge on Java SE, I think I'm able to write a bit of content to help those who are struggling on that problem, just as I did in prior contacts.

As a use case, let's use the following code fragment:

Scanner s = new Scanner(System.in);

System.out.println("Enter your name:");
String name = s.next();

import java.util.*

fun main(args: Array<String>) {
    val scanner = Scanner(System.`in`)
    val operators = listOf('^', '*', '/', '+', '-', '>', '<', '=', '#', '.', '|')
    val operands = "[a-zA-Z0-9]+".toRegex()

    abstract class Expression
    class OperandExpression(val left: Expression, val operator: Char, val right: Expression) : Expression() {
        override fun toString() = "exp($left $operator $right)"
