public class Converter {

public static void main(String[] args) { Converter and = new Converter(); ans.convert(); }

public void convert() {}

public void calculateResult(String infix) {}

public String[] readPostfix() { BufferedReader input = new BufferedReader(new InputStreamReader(System.in)); String postfixin; try { System.out.print("Input Postfix: "); postfixin = input.readLine(); return postfixin.split(" "); } catch (IOException e) { System.err.println("Input ERROR."); }

// return empty array if error occurs return new String[] {}; }
