Check out a sample textbook solution- A personal phone directory contains room for first names and phone numbers for 30 people. Assign names and phone numbers for the first 10 people. Prompt the user for a name, and if the name is found in the list, display the corresponding phone number. If the name is not found in the list, prompt the user for a phone number, and add the new name and phone number to the list. Continue to prompt the user for names until the user enters quit. After the arrays are full (containing 30 names), do not allow the user to add new entries. Use the following names and phone numbers: Name Phone # Gina (847) 341-0912 Marcia (847) 341-2392 Rita (847) 354-0654 Jennifer (414) 234-0912 Fred (414) 435-6567 Neil (608) 123-0904 Judy (608) 435-0434 Arlene (608) 123-0312 LaWanda (920) 787-9813 Deepak (930) 412-0991arrow_forwardA personal phone directory contains room for first names and phone numbers for 30 people.

- JAVA Write an application containing three parallel arrays that hold 10 elements each. The first array hold four-digit student ID numbers, the second array holds first names, and the third array holds the students’ grade point averages. Use dialog boxes to accept a student ID number and display the student’s first name and grade point average. If a match is not found, display an error message that includes the invalid ID number and allow the user to search for a new ID number.arrow_forwardwrite a (GUI) application that asks a user how many integers to be entered, then stores the integers in an array. Allow the user to enter all or a portion of the total integers. Display the integers from first to last, and then display the integers from last to first. Display the minimum and maximum numbers as well as the total and average of the numbers.arrow_forwardIn the composer array, create a statement that copies the string "Beethoven."arrow_forward
- Assignment 5A: Multiple Frequencies. In the last assignment, we calculated the frequency of a coin flip. This required us to have two separate variables, which we used to record the number of heads and tails. Now that we know about arrays, we can track the frequency of all numbers in a randomly generated sequence. For this program, you will ask the user to provide a range of values (from 1 to that number, inclusive) and how long of a number sequence you want to generate using that number range. You will then generate and save the sequence in an array. After that, you will count the number of times each number occurs in the sequence, and print the frequency of each number. Hints: You can use multiple arrays for this assignment. One array should hold the number sequence, and another could keep track of the frequencies of each number. Sample Output #1: What's the highest number you want to generate?: 5 How Long of a number sequence do you want to generate?: 10 Okay, we'll generate 10…arrow_forwardCreate 10 accounts in an array with id 0, 1, ..., 9, and an initial balance of $100. The system prompts the user to enter an id. If the id is entered incorrectly, ask the user to enter a correct id. Once an id is accepted, the main menu is displayed as shown in the sample run. You can enter choice 1 for viewing the current balance, 2 for withdrawing money, 3 for depositing money, and 4 for exiting the main menu. Once you exit, the system will prompt for an id again. Thus, once the system starts, it will not stop.arrow_forwardCreate an ArrayList, Named it Husnain that can hold Integers, and fill each slot with a different random value from 1-50. Display those values on the screen, and then prompt the user for an integer to search through the ArrayList, and if the item is present, say so. It is not necessary to display anything if the value was not found. If the item is in the ArrayList multiple times, it's okay if the program prints the message more than oncearrow_forward
- a class with 10 students that will take 3 exams use 3 arrays to hold the scores for each student and anoither array to hold the average of the 3 exams for each student. Print the table with the scores and averagearrow_forwardFor this exercise, please calculate two values from all of the numbers in the two dimensional array. The first value should be the sum of all numbers in the array. This should be stored in a separate "int" variable that is created outside the nested FOR loops. The second value should be the total average of all numbers in the Array. This should be stored in a separate "float" variable, also outside the nested FOR loop structure. So, in short: • Display the sum of the values in the array • Then display the average of the values in the array Please refer to the sample output below for visualization and match its style. As always: • Remember, the class name should be Lab9B. The user input is indicated in bold. Sample Output #1: Please enter the number of rows: 3 Please enter the number of columns: 2 I have 3 rows and 2 columns. I need to fill-up 6 spaces.
