Coding Practice

The Test1 program should generate a random number and print if it is evenly divisible by 2. However, the code has an error and always prints “Your number is even”, even if the random number is odd. Fix the code so that it only prints the message when the number is even.

The Test2 program should check your guess against the answer and print that it is too low, correct, or too high. However, the code has errors. Fix the code so that it compiles and runs correctly.

The Test3 program should print “You can go out” if you have done your homework and cleaned your room. However, the code has errors. Fix the code so that it compiles and runs correctly.

The Test4 program should print if x is in the range of 0 to 10 (including 0 and 10). However, the code has errors. Fix the errors so that the code runs as intended.

The Test5 program should print if x is less than 0, equal to 0, or greater than 0. Finish it to work correctly.

Finish the Test6 program so that it prints You can go out if you have a ride or if you can walk and otherwise prints You can't go out. Use a logical or to create a complex conditional.

Finish the Test7 program to print you can go out if you don’t have homework and you have done the dishes.

Finish the Test8 program so that it prints You have a fever if your temperature is above 100 and otherwise prints You don't have a fever.

Finish the Test9 program to print It is freezing if the temperature is below 30, It is cold if it is below 50, It is nice out if it is below 90, or It is hot using nested if else statements.

Rewrite the Loop1 program to use a while loop instead of a for loop to print out the numbers from 1 to 10 (inclusive).

Rewrite the Loop2 program so that it uses a for loop instead of a while loop to print out all the integers from 5 to 15 (inclusive).

Rewrite the Loop3 program to use a while loop instead of a for loop to print out the numbers from 10 to 100 by 10’s (inclusive).

The Loop4 program should print the values from 1 to 10 (inclusive) but has errors. Fix the errors so that the code works as intended. If the code is in an infinite loop you can refresh the page in the browser to stop the loop and then click on Load History and move the bar above it to see your last changes.

The Loop5 program should print the values from 10 to 5, but it has errors. Fix the errors so that the code works as intended.

The Loop6 program should print the values from 10 to 1, but it has errors. Fix the errors so that the code works as intended.

Finish Loop7 program to print a countdown from 100 to 0 by 10’s using a for or while loop.

Finish the Loop8 program to print the value of x and " is even" if x is even and " is odd" if it is odd for all values from 10 to 1.

Finish the Loop9 program to print the values for 10 * x where x changes from 0 to 10 using a loop.

Finish the Loop10 program so that it prints a string message minus the last character each time through the loop until there are no more characters in message. The loop condition should test the length of the message. The loop body should print the message and then use substring to create a new message without the last character.

Finish Loop11 program to loop printing the message each time through the loop and remove an x from the message until all the x’s are gone.

Write a loop in the Loop12 program to print the number of x’s in the string message. Use the indexOf and substring methods.

Write the Loop13 program to print a rectangle of stars (*) with 5 rows of stars and 3 stars per row. Hint: use nested for loops.

Write the Loop14 program to print a rectangle of stars (*) with 3 rows of stars and 5 stars per row.

Write the Loop15 program to print 55555, 4444, 333, 22, 1 with each on a different line.
