2. Write a program that prints the following patterns separately, one below the other. Use for loops to generate the patterns. All asterisks (*) should be printed by a single printf statement of the form printf( "%s", ** }; (this causes the asterisks to print side by side). [Hint: The last two patterns require that each line begins with an appropriate number of blanks.) (A) (B) (C) ********** (D) ***** ******** ********* *** ******* ******** *** **** ******* ***** 時 由 由会 ***** ****** 時 ***** ****** ******* **** **** ******* ******** *** *** ******** ******** ** ********* ******* ** **********

4. In IntelliJ: By using java code a) Turn the For loop into a loop that adds the numbers from 50 to 1 and execute it. b) Turn the While loop into a loop that adds the numbers from 1 to 50, but does not add the number 25, and execute it. c) Turn the Do-while loop into a loop that add all numbers from 50 to 1, but does not add neither number 25, 27 and 37, excute it

How do I write the while loop using a sentinel value to control the loop, and also write the statements that make up the body of the loop? Also including the calculations to compute the average rating.

3. Write a program called NestedLoop that prints the below. Use a for nested loop. No credit if nested loop is not used. (10 pnts) 1 22 333 4444 55555

12. Write a loop of the specified type that sums up the even integers between 1 and 21. a. a while loop b. a for loop
