Write a program in java to translate infix mathematical expression into postfix expression and a program to evaluate the postfix expression. There should be three separate programs . use stack data abstraction and class implementation. the program has three versions. the first version uses array implementation, the second version uses linked list, and the third one uses double linked list stack implementation in the abstraction . First read and output data using std,then use the file . use the stds only for the first version.
