Loops are frequently used to<u> validate data </u>that is, to make sure it is meaningful and useful.

<h3>What are common blunders made by programmers in coding loops?</h3>

Forgetting to initialize and alter the loop control variable are common mistakes that programmers occasionally make. One set of instructions operates on multiple, separate sets of data. Initialized before joining a while loop.

<h3>What are the three steps that should occur in every loop?</h3>

Provide a starting value for the variable that will contain the loop.
Test the loop control variable to decide whether the loop body executes.
Alter the loop rule variable.

lys-0071 [83]

Answer:

Following are the code to this question:

import java.util.*; //import package for user input

class RetailItem//defining class RetailItem

{

private String desc;//defining String variable

private int unit;//defining integer variable

private double prices;//defining double variable

RetailItem()//defining default Constructor

{

//Constructor body

}

Output:

The Sub Total value: 199.75

The Sales Tax value: 11.985

The Total value: $211.735

Explanation:

In the above code three class "RetailItem, CashRegister, and Main" is defined, in the class "RetailItem", it defines three variable that is "desc, unit, and prices", inside the class "get and set" method and the constructor is defined, that calculates its value.

In the next step, class "CashRegister" is defined, and inside the class parameterized constructor is defined, which uses the get and set method to return its value.

In the next step, the main class is declared, in the main method two-class object is created and calls its method that are "getSubtotal, getTax, and getTotal".

There is some technical error that's why full code can't be added so, please find the attached file of code.

tekilochka [14]

Answer:

The following are the program to the given question:

import java.util.*;//import package for user input

public class Make //define class Make

{

public static void main(String[] ask) //define a main method

{

Scanner obx = new Scanner(System.in); //declare the Scanner class object

int size=obx.nextInt(); //get the size of the array from the user

int a[]=new int[size]; //declare an integer array with given size

String word[]=new String[size]; //declare a string array with given size

for(int i=0;i<size;i++) //set the for loop

word[i]=obx.next(); //get string input from the user

for(int i=0;i<size;i++) //iterates with the array, increase the count

{

for(int j=0;j<size;j++) //defining a loop to check value

{

if(word[i].equals(word[j])) //use if to check that elements of words

a[i]++;//increamenting array size

}

System.out.print("\n"); //use print for break line

for(int i=0;i<size;i++)//set for loop to print the following result

System.out.println(word[i]+" "+a[i]);//print value

}

Output:

Please find the attachment file.

Explanation:

First, establish the predefined package required and instead define the main class and define the main method within the class and method.
Declare the scanner class object and receive an object size in the 'size' variable thru the array.
Next create two arrays, the integer type "a" with both the input size given and the string type "word" with the input size supplied.
Define the loop for which string array elements are acquired and set two to again for loop, which increases with loop iteration the integer data type array by one.
Lastly, set the loop for which this result is printed.
