Infix to Postfix Notation (24 to 48 hours)

Design, implement, and test a JAVA program that read infix expressions from a file, [url removed, login to view], converts the infix expression to postfix notation, and evaluates the postfix expressions. We make the following Simplifying assumptions:

1) All operators and operands are one character long in the original infix expression

2) Allowable operators are +, -, *, / (integer division), ^ (exponentiation).

3) All operators are left associative

3) There are no unary operators

4) Each expression is contained on its own line withing the file

5) Parentheses can of course be used in normal fashion, and blanks should be allowed between symbols

The infix expressions below should be read into the program from a file, [url removed, login to view]

1: 8 + 4 * 2 - 6

2: 7 * 2 - 4 * 3 + 2 * 5

3: 2 * 3 * 4 - 8 + 9 / 3 /3

4: 5 + 7 * 4 - 6

5: 4 * ( 3 + 2 * 4) - 7

6: ( 5 + 7 ) / ( 9 - 5)

7: 3 * ( 5 * ( 5 - 2 ) ) - 9

8: ( ( 5 * ( 4 + 2 ) - ( 8 + 8 ) / 2 ) - 9 ) ^ 3

9: ( ( 5 + 5 * ( 6 - 2 ) + 4 ^ 2 ) * 8 )

10: ( ( ( 3 ^ 4 ) ) )

Be sure that the program outputs the original infix expression, its postfix equivalent, as well as the evaluation of the postfix expression. All outpout should be sent to a file called csis.txt.

The only stack class that should be used in this lab is the ObjectStack class that will be provided in a .txt file.

You should use at least the following classes and interface for the project.

Driver

ObjectStack

ObjectStackInterface

InfixToPostfix

EvalPostfix

The only user-defined static function should be main(). No floats, doubles, or scientific notation should be used.

The program should be able to handle the following ill-formed expressions, indicating that such an expression is erroneous, identifying the type of error, and going on to process the nest infix expression.

1 + * 2

1 2 * 3 ^ 4

( 1 + 2

( 1 + 2 ) * 3 )

You can use Java's Scanner class to open a file for input

Required declarations:

import java.io.*;

import [url removed, login to view];

public static void mains(String[] args) throws IOException {

To open a file for input and create a Scanner Object:

Scanner filescan = new Scanner(new File("[url removed, login to view]"));

To read a line from the file using the Scanner object:

while ([url removed, login to view]()) {

String buf = fileScan,nextLine();

To close the Scanner object:

[url removed, login to view]();

The conversion from infix to postfix will require the comparison of operator priorities. Here's a method that will take an operator as input and retunr its priority:

private int priority(char op) {

switch (op) {

case '^': return 3;

case '*':

case '/': return 2;

case '+':

case '-': return 1;

default : return 0;

}

}

Every class must have a Javadoc class comment

Every method must have a Javadoc method comment

Every method parameter must have an @param tag

Every method with a return statement must ahve an @return tag

Generate the HTML Javadoc documentation

Each data structure must implement an interface for that data structure. The interface files must be included.
