- Create a Java program that declares and initializes two integer variables, "num1" and "num2", with values of your choice Output the values of "num1" and "num2" to the console using the System.out.println() method. Use the addition operator (+) to add "num1" and "num2" together and output the result to the console. Use the subtraction operator (-) to subtract "num2" from "num1" and output the result to the console. Use the multiplication operator (*) to multiply "num1" and "num2" together and output the result to the console. Use the division operator (/) to divide "num1" by "num2" and output the result to the console. Use the modulus operator (%) to find the remainder when "num1" is divided by "num2" and output the result to the console. Use the increment operator (++) to increment the value of "num1" by 1 and output the new value to the console. Use the decrement operator (--) to decrement the value of "num2" by 1 and output the new value to the console.java You must print the number declared double x; on the screen. With which of the following options do you know that a number in the range -9999.99999 to 9999.99999 is printed with exactly 4 decimals and that all numbers in the number are displayed? Choose an alternative: a.System.out.format ("%. 4f", x); b.System.out.format ("% 4.1f", x); c.System.out.format ("% b", x); d.System.out.format ("% s", x); e.System.out.format ("% d", x);Question 1: With Java, Write a program that will ask the user to enter the following personal information about himself/herself (full name, address, date of birth, phone), store each in a variable, the program will then print them, each on a separate line using one print statement.

- Write a java program called Sales considering the following directions and the sample run. Practice here first the write answer on the answer sheet. Also, make sure to distinguish high and low caps as Java is case - sensitive. - import and declare a Scanner class - declare three floating – point variables named price, discount, and discountPrice - ask the user for the price (print statement) and get the price (Scanner) from the user - calculate the discount if price is less than 100, then the discount is 10% of price, else discount is 14% of price - print the discounted prices for the item Sample Run Enter the price 90.0 The discount price is 81.0 Enter the price 200.0 The discount price is 172.0Write a java program that declares the following int variables with the assigned values: a = 4; b = 12; c = 37; d = 51; NOTE: You do not have to use scanner to input the values of your variables. Just assign them when initializing the variable (i.e. int a = 4;). The program should compare the following variables and display the indicated message (not the int value), for instance print out "a < b" not "4 < 12": a < b – Display: “a < b” a > b – Display: “a > b” d <= c – Display: “d <=c” c != d – Display: “c !=d” What is the value of result after the following Java statements execute (assume all variables are of type int)? Create a program to prove your answer. In the comments section at the beginning of your program, type in the definition of modulus. Display a statement during execution of the program that looks something like this: "The result of d % a * c + a % b + a = ___", the underscore should…Create a java program that reads integers from the user until the enter key is pressed. Oncea allof the integers have been read your program should display all of the negativen numbers followed by all of the zeros, followed by all of the positive numbers. Withine eachgroup the numbers should be displayed in the same order that they were enteredbyt theuser. For example, if the user enters the values 3, -4, 1, 0, -1, 0, and -2 thenyourp programshould output the values -4, -1, -2, 0, 0, 3, and 1. Your programshould displaye eachvalue on its own line.
