Questions

1. What is the purpose of control flow statements in Java?
Answer: To control the flow of program execution
Explanation: Control flow statements in Java are used to determine the order in which statements are executed in a program.Report for correction
2. Which control flow statement is used to execute a block of code repeatedly as long as a condition is true?
Answer: do-while loop
Explanation: The do-while loop in Java repeatedly executes a block of code as long as the specified condition is true.Report for correction
3. Which control flow statement is used for making decisions based on a condition?
Answer: if-else statement
Explanation: The if-else statement in Java allows you to make decisions based on a condition.Report for correction
4. What is the role of the break statement in a loop?
Answer: It exits the loop prematurely
Explanation: The break statement is used to exit a loop prematurely in Java.Report for correction
5. Which control flow statement is used to specify a default case in a switch statement?
Answer: default
Explanation: In a switch statement, the default case is executed if none of the other cases match the expression value.Report for correction
6. What is the result of the following code snippet?javaCopy codeint x = 10;if (x > 5) { System.out.println("x is greater than 5");} else { System.out.println("x is not greater than 5");}
Answer: "x is greater than 5"
Explanation: The condition x > 5 is true, so the code inside the if block is executed.Report for correction
7. In a for loop, what does the initialization statement do?
Answer: It initializes loop variables
Explanation: The initialization statement in a for loop is responsible for initializing loop variables before the loop starts.Report for correction
8. How can you exit a while loop prematurely?
Answer: Using the break statement
Explanation: The break statement can be used to exit a while loop prematurely in Java.Report for correction
9. What is the purpose of the continue statement in a loop?
Answer: It skips the current iteration and continues with the next one
Explanation: The continue statement is used to skip the current iteration of a loop and continue with the next one.Report for correction
10. Which control flow statement is used to execute a block of code repeatedly for a specified number of times?
Answer: for loop
Explanation: The for loop in Java is used to execute a block of code for a specified number of times.Report for correction
11. What is the result of the following code snippet?javaCopy codeint i = 1;while (i <= 5) { System.out.print(i + " "); i++;}
Answer: 1 2 3 4 5
Explanation: The while loop prints the values of i from 1 to 5.Report for correction
12. What does the switch statement evaluate to determine which case to execute?
Answer: Integer expression
Explanation: The switch statement in Java evaluates an integer expression to determine which case to execute.Report for correction
13. Which control flow statement is used to handle exceptions in Java?
Answer: try-catch statement
Explanation: The try-catch statement is used to handle exceptions (errors) in Java.Report for correction
14. What is the role of the default case in a switch statement?
Answer: It is executed when no other case matches
Explanation: The default case in a switch statement is executed when none of the other cases match the expression value.Report for correction
15. What happens if the condition in a do-while loop is false initially?
Answer: The loop executes once
Explanation: In a do-while loop, the loop body is executed at least once, even if the condition is false initially.Report for correction
16. In Java, how do you specify multiple conditions in a single if statement?
Answer: Separate conditions using ampersands
Explanation: You can specify multiple conditions in a single if statement using the logical AND operator (&&) to combine them.Report for correction
17. What is the purpose of the else if statement in Java?
Answer: To specify an alternative condition
Explanation: The else if statement in Java allows you to specify an alternative condition to be checked if the preceding if condition is false.Report for correction
18. What is the result of the expression true && false in Java?
Answer: false
Explanation: The && operator in Java represents the logical AND operation, and the result is false if any of the operands is false.Report for correction
19. Which Java access modifier allows a member to be accessed only within its own class?
Answer: private
Explanation: The private access modifier restricts access to members only within the same class.Report for correction
20. What is the purpose of the this keyword in Java?
Answer: It refers to the current instance of the class
Explanation: The this keyword in Java is used to refer to the current instance of the class.Report for correction
21. Which Java loop is used when you want to execute a block of code at least once?
Answer: do-while loop
Explanation: The do-while loop in Java is used when you want to execute a block of code at least once, as the condition is checked after the loop body.Report for correction
22. What is the result of the expression 5 / 0 in Java?
Answer: Error
Explanation: Attempting to divide by zero in Java results in an error or exception.Report for correction
23. Which Java keyword is used for method overriding?
Answer: @Override
Explanation: The @Override annotation is used in Java to indicate that a method is intended to override a method from its superclass.Report for correction
24. What is the purpose of the super keyword in Java?
Answer: It calls a method from the superclass
Explanation: The super keyword in Java is used to call a method or access a member from the superclass.Report for correction
