Write a JavaScript function that takes a random array of integers (use math lib for random generation) as input parameter, and returns the largest even integer among them. Use loops and conditional statements. Don’t use min or libraries to automatically get the largest number. Tips: Import the JS code into an HTML, and call the function when the page is loaded. Print the output of the function in the browser console. Use math lib to generate a random array of integers

In java Develop a menu-based shape-maker, using randomly generated sizes & characters: pyramid, inverted pyramid, diamond, and hourglass. Use functions to perform tasks, including separate functions for generating a random integer in a range and for generating a random character in a range. The four different shapes are made from a randomly generated printable character and a randomly generated maximum width between 4 and 12. Beneath the shape, print a descriptive caption stating the symbol and the maximum width.Define the random integer and random character functions in a separate class in a separate source code file and call these functions from the shape maker.
