Application: ------------ You are required to write a JAVA program that takes a symbolic infix expression as input and converts it to postfix notation, enter the values of each symbol, evaluates the postfix expression and outputs the resulting expression and its value. All operands are integer values, but intermediate results could be floating points. Your program should support the operators +, -, * and /. Expressions can contain parentheses. You should use the stack implementation you did in part (A) for any stack data structure needed in the program. Postfix Vs. Infix Notations: -------------------------- The standard way of writing expressions is known as infix notation because the binary operator is placed in-between its two operands.Although infix notation is the most common way of writing expressions, it is not the one used by compilers to parse expressions. Instead, compilers typically use a parenthesis-free notation referred to as postfix. In this notation, each operator appears after its operands. Evaluating Postfix Expressions: ------------------------------- The postfix expression is scanned left-to-right. Operands are placed on a stack until an operator is found. Operands are then removed from the stack, the operation is performed on the operands and the result is pushed on to the stack. The process continues until the end of expression is reached.
