Programming Project: Expression TreesThis project is adapted from Project 1 of Chapter 9 of the textbook. It deals with a simple kind of expression trees, in which there are two kinds of nodes:(a) Leaf nodes, which contain a real number as their clement; and(b) Non-leaf nodes, which have exactly two children and contain one of these characters as their element: +, -, * and /. These characters represent arithmetic operations and have usual interpretations.Implement a class for expression trees with these operations:(a) A constructor that builds an expression tree. It accepts a String that represents a grammatically correct expression as its sole input. Hint: refer to a previous assignment on evaluating expressions.(b) A recursive method named eval that evaluates a non-empty expression tree using these rules:i. If the tree has only one node (which must be a leaf), then eval returns the real number that is the node's clement;ii. If the tree has more than one node and the root contains op where op is one of +, -, * and /, then eval first evaluates the sub-trees of the root and returns the real number obtained by performing operation op on the results from evaluating the sub-trees.(c) A recursive method named infix that output the expression represented by a non-empty expression tree to a String in infix format.(d) A recursive method named postfix that outputs the expression represented by a non-empty expression tree in postfix format.You also need to write another class that applies the operations of the above class.Please submit1. Analysis: test data;2. Design:
3. Code;4. Screen snapshots of test runs.
This exercise begins with information for a building project. Working in Microsoft Project, you will create the task list, including summary tasks and their sub-tasks, create links between tasks and their predecessors, add resources, and make chan..
