Final Exam - JAVA

What statement is used to iterate through elements in an array in many programming languages?

• for loop

• do-while loop

• while loop

• switch statement

Which loop is suitable for situations where the loop condition needs to be checked after the loop body execution?

• for loop

• do-while loop

• while loop

• switch statement

What does a nested loop refer to in programming?

• A loop that contains multiple statements

• A loop that has multiple exit conditions

• A loop that is defined within another loop

• A loop that only executes once

Which statement best describes the purpose of a break statement in a loop?

• Terminates the loop and continues with the next iteration

• Skips the current iteration and moves to the next iteration

• Ends the program execution

• Executes the loop indefinitely

In a nested loop scenario, how many times will the inner loop execute if the outer loop executes 5 times and the inner loop executes 3 times per iteration of the outer loop?

• 3

• 5

• 15

• 18

What is the purpose of using arrays in programming?

• To store only strings

• To store data of the same type in a contiguous memory location

• To store data of different types in a single variable

• To perform arithmetic operations efficiently

Which of the following best describes an array index?

• The number of elements in the array

• The position of an element within the array

• The total memory allocated to the array

• The data type of the array

What is the benefit of using a for loop over a while loop?

• A for loop can't be used to iterate over arrays

• A for loop is simpler and more concise

• A for loop is less efficient than a while loop

• A for loop doesn't allow iteration based on a condition

Which statement about arrays is correct?

• Arrays cannot store more than one type of data

• Arrays are always fixed in size once declared

• Arrays can only store primitive data types

• Arrays can dynamically resize themselves

What will be the result of accessing an array element with an index that is out of bounds?

• The program will crash

• The element will be added to the end of the array

• It will return the last element of the array

• It may cause an error or unexpected behavior
