Write a Java program which implements a stack for checking whether a parenthesized expression is correctly parenthesized. The program should prompt the user to enter the parenthesized expression. The expression entered by the user should then be (1) displayed – with an appropriate label, (2) checked and (3) then an appropriate message relative to whether the expression is correctly parenthesized or not should be printed. If the expression is not correctly parenthesized, the user should be given the reason.

Jennifer has to set up a network in a factory with an environment that has a lot of electrical interference. which cable would she prefer to use? jennifer would prefer to use because its metal sheath reduces interference.

This program should be a short piece of code that prints all of the positive integers from 1 to 100 as described more fully below. the program may contain multiple methods, and if using an oo language, should be contained within a single class or object. the program should be designed so that it begins execution when invoked through whichever mechanism is most common for the implementation language. â–ş print out all positive integers from 1 to 100, inclusive and in order. â–ş print messages to standard output, matching the sample output below. â–ş in the output, state whether the each integer is 'odd' or 'even' in the output. â–ş if the number is divisible by three, instead of stating that the number is odd or even, state that the number is 'divisible by three'. â–ş if the number is divisible by both two and three, instead of saying that the number is odd, even or divisible by three; state that the number is 'divisible by two and three'. â–ş design the logic of the loop to be as efficient as possible, using the minimal number of operations to perform the required logic. sample output the number '1' is odd. the number '2' is even. the number '3' is divisible by three. the number '6' is divisible by two and three.
