1. Write a program to define the following variables, assign them values, and print their values on screen: Integer x = 20, Float y = 40.45 Double z = 91.51e+5 Char w = A For the integer variable x, you need to print it in decimal notations, octal notations and hexadecimal notation. For the double variable y, you need to print it in double notations and scientific notation. 1.
