Statements that affect the order in which code is being run are called

• If statements

• While statements

• Control Structures

• Loops

Insert the missing line of code so that the loop iterates until a newline is entered.

• (input = scanner.nextLine()).length() > 0

• (scanner.nextLine() = input).length() > 0

• (scanner.nextLine() = input).length() == 0

• (input = scanner.nextLine()).length() == 0

Conditional expressions are called

• While expressions

• If expressions

• Switch expressions

• Ternary expressions

This statement must be inserted after a switch case to prevent fallthrough

• continue;

• break;

• return;

• goto;

These are values that are passed into a method by the method caller

• Return value

• Variables

• Arguments

• Constants

Complete the for loop such that the output prints the numbers from 1-10

• int i = 1; i < 10; i++

• int i = 1; i <= 10; i++`

• int i = 0; i < 10; i++

• int i = 0; i <= 10; i++

How many of the following snippets of code can be inserted such that the full code compiles and runs without any error

int i = 1; i <= numbersArray.length; i++

int i = 0; i < numbersArray.length; i++

int i : numbersArray

int i : numbersArray[]

• 1

• 2

• 3

• 4

This refers to the name of the method and the names + types of its parameters

• Method declaration

• Method signature

• Method implementation

• Parameter list

What's the difference between the while loop and the do-while loop?

• The while loop consumes less resources than the do-while loop, at the cost of taking longer to execute.

• The do-while loop evaluates the condition after every iteration, the while loop evaluates the condition before every iteration.

• The while loop is counter controller loop while the do-while loop is not.

• There are no differences, it is purely aesthetic.

How many of the following integer array declarations are valid?

• 1

• 2

• 3

• 4
