I need help please in this Advanced Java Assignment, it's a project that I have to submit. Much appreciated in advance and many thanks!

Concepts Stacks Queues Programming Problems Stack- Implementation. You will be able to use the push, pop and peek of Stack concept Post-Fix calculator -When an arithmetic expression is presented in the postfix form, you can use a stack to evaluate the expression to get the final value. For example: the expression 3 + 5 * 9 (which is in the usual infix form) can be written as 3 59 +in the postfix. More interestingly, post form removes all parentheses and thus all implicit precedence rules. Use the stack concept to create a post-fix calculator. Queue Implementation. Palindrome Checker - A palindrome is a string that is the same forwards as backwards. For example, the following strings are palindromes: " ", "a", "aa", "bb", "aba", "bab", "bob" These are not ab", "ba", "bba", "abb" Use the Queue concept to create a palindrome checker. Submission: Please submit two separate projects for each concept. In addition, please submit a word document with all the code pasted in. Also, embedded with screenshots of the tested output to prove your data structure code works
