Question 1

Rewrite the code snippets below as specified in each part. Where necessary, you may assume that all involved variables and/or methods are already properly defined and/or initialized.

Submit your answers directly in the answer box, making sure to mark clearly the answers to the three parts.

Part A (5 pts):

The following code snippet assigns a value to the int variable price, depending on the String object item:

if (!item.equals("car"))

 price = 190;

else

 price = 12000;

Transform the above logic into a single equivalent assignment statement, using the conditional operator ?:.

Part B (10 pts):

The following code snippet calls a different method according to the value of the int variable choice:

if (choice == 1)

 retry();

else if (choice == 2 || choice == 3)

 proceed();

else

 goBack();

Transform the above logic into an equivalent switch statement.

Part C (10 pts):

In the following code snippet, total is an int variable:

int num = total;

while (num >= 0) {

 System.out.println(num);

 num = num - 2;

}

Transform the above into an equivalent for loop.
