Problem 2: Displaying Multiples of a Number Overview Develop a java program to calculate the multiples of a given number using a for loop. Task Have the user enter a number, and then use a for loop to display all the multiples of that number from 1 to 12. Expected Output: Choose a number: 7 7x1 = 7 7x2 = 14 7x3 = 21 7x4 = 28 7x5 = 35 7x6 = 42 7x7 = 49 7x8 = 56 7x9 = 63 7x10 = 70 7x11 = 77 7x12 = 84
Types of Loop
Loops are the elements of programming in which a part of code is repeated a particular number of times. Loop executes the series of statements many times till the conditional statement becomes false.
Loops
Any task which is repeated more than one time is called a loop. Basically, loops can be divided into three types as while, do-while and for loop. There are so many programming languages like C, C++, JAVA, PYTHON, and many more where looping statements can be used for repetitive execution.
While Loop
Loop is a feature in the programming language. It helps us to execute a set of instructions regularly. The block of code executes until some conditions provided within that Loop are true.

![Problem 1: Validate a Bank PIN
Overview
Develop a java program to validate bank PIN of a customer. Use a while loop to repeat code until a valid PIN
is entered.
9.
Task
1. Declare a valid integer PIN.
2. Prompt the user to enter the PIN.
3. In a while loop, perform the following steps:
o Compare the user-entered PIN with the already declared PIN.
o If the entered PIN is not the same, prompt the user to enter the PIN again.
o Repeat the loop until the correct PIN is entered.
4. Print a message confirming that the correct PIN has been entered and that the user now has access to their
account.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fb599394f-64cd-4bff-bebb-d3de695f8708%2F50cf7bfb-5991-42f5-a6e8-889be7632432%2F3h6w8s3_processed.jpeg&w=3840&q=75)
