This document presents a solution for a Postfix Calculator project implemented in Java, addressing the requirements of a computer science assignment. The project involves creating a program that evaluates postfix expressions using a singly linked list to manage a stack. The solution includes detailed explanations of the code, including variable declarations, the use of the BufferedReader class for file input, and the implementation of a 'Singly linked list' class for stack operations. The program utilizes a switch-case method for handling different operators (addition, subtraction, multiplication, and division). The algorithm involves scanning tokens, pushing operands onto the stack, and popping operands and operators to perform calculations. The project also includes test cases and a conclusion summarizing the program's efficiency and the benefits of using data structures. The provided references support the concepts and techniques used in the implementation.
