Please help with user input with "Scanner" function in Java. I like to have this below code to work as a calculator with "get and set" methods. As it is now it's only return fix output as I set to 2 + 4 below. How can I correct the code so the user put in for example 2 + 4 and get the sum 6 at print output. Thanks!  public class Main { public static void main(String[] args) { Calc calc = new Calc(); calc.setCalc(); System.out.println(calc.getCalc()); } }

public class Calc { public Calc() { } public int getCalc() { return 2 + 4; } public void setCalc() { } }
