Description
1. Write a Java program by using three for loops to print the following pattern:
1******
12*****
123****
1234***
12345**
123456*
1234567
2.CheckOddEven (if-else): Write a program called CheckOddEven which prints “Odd Number” if the int variable “number” is odd, or “Even Number” otherwise.
The program shall always print “BYE!” before exiting.
3.PrintNumberInWord (nested-if, switch-case):
Write a program called PrintNumberInWord which prints “ONE”, “TWO”,… , “NINE”, “OTHER” if the int variable “number” is 1, 2,… , 9, or other, respectively.
Use (a) a “nested-if” statement; (b) a “switch-case” statement.
4.Write a program called SumAndAverage to produce the sum of 1, 2, 3, …, to 100. Also compute and display the average. The output shall look like:
The sum is 5050
The average is 50.5
5.Modify the above program
a)To sum only the odd numbers from 1 to 100, and compute the average. (HINTS: n is an odd number if n % 2 is not 0.)
b)Too sum those numbers from 1 to 100 that is divisible by 7, and compute the average.
c)To find the “sum of the squares” of all the numbers from 1 to 100, i.e. 1*1 + 2*2 + 3*3 + … + 100*100.
6.Write a program called Product1ToN to compute the product of integers 1 to 10 (i.e., 1×2×3×…×10).
Try computing the product from 1 to 11, 1 to 12, 1 to 13 and 1 to 14. Write down the product obtained and explain the results.
7. PrintPattern (nested-loop): Print each of the followings patterns using nested loops.
