The Math class provides a static method , max, that accepts two int arguments and returns the value of the larger one.
Four int variables , population1, population2, population3, and population4 have already been declared and initialized.
Write an expression (not a statement !) whose value is the largest of population1, population2, population3, and population4 by calling max.
Math.max(Math.max(population1, population2), (Math.max(population3, population4)))
