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:

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:

Transform the above logic into an equivalent switch statement.

Part C (10 pts):

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

Transform the above into an equivalent for loop.

Explanation / Answer

Part A

Given code is converted to

price = (!item.equals("car")) ? 190 : 12000;

The syntax is variable = condition ? <true part> : <false part>;

Part B

Code converted to Switch statement is as follows

switch(choice) {

case 1:

retry();

break;

case 2:

case 3:

proceed();

break;

default:

goBack();

}

Part C

Equivalent code in for loop is

for(int num = total; num >= 0; num = num -2) {

System.out.println(num);

}
