I need this code to be split up into two different classes. One class is the driver that will exicute the code. the other will contain the methods to do the calculations. current output is correct just all in one file

/* postfix2infix/Postfix2infix.java */ package postfix2infix;

import postfix2infix.LinkedStack; import java.io.*;

public class Postfix2infix { public static void main(String [] arg) { BufferedReader input = new BufferedReader (new InputStreamReader(System.in));

String choice = new String("Y");

do { try { System.out.println("Enter a postfix expression:"); String infixStr = input.readLine();

String [] elements = infixStr.split("\\s+"); // split around series of whitespaces

LinkedStack stack = new LinkedStack();

for(int i = 0; i

//top of stack contains the infix expression, stack should be of size 1 if(stack.size() == 1) { System.out.println("In Infix Notation: " + stack.pop()); } else { System.out.println("Malformed post fix expression"); } } catch (Exception e) { e.printStackTrace(); }

System.out.print("Translate another expression [Y/N]? "); try { choice = input.readLine(); } catch (Exception e) { e.printStackTrace(); } } while(choice.compareToIgnoreCase("Y") == 0); } }
