Loops and Methods in Java

What is the syntax for a do-while loop in Java?

What is the purpose of a do-while loop in Java?

• To execute a block of code only once and then terminate the loop.

• To execute a block of code multiple times without any condition.

• To execute a block of code based on a specific condition and then terminate the loop.

• To execute a block of code at least once, and then repeat the execution as long as a certain condition is true.

How many times will a do-while loop execute if the condition is false?

• 3

• 0

• 1

• 2

What is the difference between a while loop and a do-while loop in Java?

• A while loop checks the condition after executing the loop, while a do-while loop checks the condition before executing the loop.

• A while loop can only be used for finite iterations, while a do-while loop can be used for both finite and infinite iterations.

• A while loop can have multiple conditions, while a do-while loop can only have one condition.

• A while loop checks the condition before executing the loop, while a do-while loop checks the condition after executing the loop.

Write a Java code snippet to demonstrate the usage of a do-while loop.

• int i = 0; while(i < 5) { System.out.println(i); i++; }

• int i = 5; do { System.out.println(i); i--; } while(i > 0);

• int i = 0; do { System.out.println(i); i++; } while(i < 5);

What is the syntax for defining a method in Java?

What is the purpose of a method in Java?

• The purpose of a method in Java is to handle exceptions.

• The purpose of a method in Java is to perform a specific task and encapsulate a set of instructions.

• The purpose of a method in Java is to define a class.

• The purpose of a method in Java is to store data.

What is the difference between a method declaration and a method call in Java?

• A method declaration is the process of defining a method in a class, while a method call is the process of invoking or executing a method that has been declared.

• A method declaration is the process of defining a method in a class, while a method call is the process of declaring a method in a class.

• A method declaration is the process of declaring a variable in a method, while a method call is the process of assigning a value to that variable.

• A method declaration is the process of invoking or executing a method that has been declared, while a method call is the process of defining a method in a class.

Write a Java method to calculate the factorial of a given number.

What is method overloading in Java?

• Method overloading in Java is the ability to define multiple methods with different return types but the same parameters in a class.

• Method overloading in Java is the ability to define multiple methods with different names but the same parameters in a class.

• Method overloading in Java is the ability to define multiple methods with the same name but different parameters in a class.

• Method overloading in Java is the ability to define multiple methods with the same name and same parameters in a class.
