You can create one java project, named as Assignment1_id and add separate java file for each question. You can name your javá files as 01.02.... etc. • Make sure that you include your student ID name and section number as comments at the beginning of each file. • Cheating or copying codes from books, students internet, etc., is not . if required, your instructor may request to meet you to discuss and review your submission. Not attending the meeting considers your Submission as not complete. Sllowed 1. Write a program that reads three integer numbers from user and prints the numbers in ascending order. 2. Write an application that asks the user to enter his income for first six months of the year. The program then calculates and displays the total, the average, the maximum and the minimum income of the user during six months 3. Write a program that finds and prints the first 10 prime numbers. Please note that a prime number is one which is divisible only by 1 and by itself. First four prime numbers are 1. 2. 3. and S. 4. Write a program that find the value of y using the formula given below for first 10 even values of X. y=3X+5x+7 5. Write a program that asks the user to enter a sequence of odd numbers. The program should stop as soon as the user enters an even number. Your program should display how many odd numbers user entered before entering an even number 6. Write a program that generates 1000 random numbers between 1 and 100. Your program should calculate and print how many numbers were between 30 and 40 (including both) 403-CS120/C5101-Assignment-1, 6/20/2020 Page 1 of 2 Jubail University College Computer Science & Engineering Department 7. Write a program that asks the user to enter his score between 1 and 100 and prints its grade according to following table Score Between Letter Grade O and 59 F 60 to 69 D 69 to 79 с 79 to 89 B 89 to 100 8. Modify your program in 07 such that if the user score is near the border that is letter grade can be changed by giving up-to two extra marks than assign the next grade to the user. Test your program with his new criteria.
