1. Declare an array capable of holding 4 integers. It must be 4 integers only in the
declaration. int[ ] array = new int[4];
2. Loop prompting the user to enter values to insert into the array until they enter a -1. For
simplicity, we will assume users will only enter values greater than 0.
3. You will need to check to see if the array is full before inserting the value in the next
available spot in the array.
4. If the array is full you will need to invoke the method,
Page 2 of 4
public static int[] expandArray(int[ ] array)
that will double the size of the array and copy in the contents of the array.
5. Include the method
public static void displayArray(int[ ] array)
that will display the contents of the array.
6. Your main will contain the loop that prompts user to enter a value or -1 to indicate to
quit. User will only enter values greater than 0. Insert the value into the next available
slot in the array. You need to check to see if there is room in the array prior to inserting.
After the user enters -1 and the loop terminates, display the contents of the array by
calling displayArray. Hint: your main will want to keep track of the next available index
into the array.
7. When testing your program try to enter 10 values.
The program is written in Java. Please check the source code and output in the following steps.

- 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_forwardIn visual basic Write the code that will sequentially search through the array strFirstNames and will print out the word "Found" if the name "Brian" is in the array.arrow_forwardThe Fibonacci numbers are 0, 1, 1, 2, 3, 5, 8, 13, ... where each number (after the first two values) is the sum of the previous two numbers. Write a program that declares an integer array called fib_numbers with a length of 25 elements. The program then fills the array with the first 25 Fibonacci numbers using a loop. The program then prints the values to the screen using a separate loop.arrow_forward
- Use an array. The program should read 25 integers from a user. Each value should be between 5- 100 (5<-value<-100). As the user inputs values store all the values which are not a duplicate. Print all the array values at the end. Use the smallest possible array.arrow_forwardProblem Description - JAVA PROGRAMMING Use a Two-dimensional (3x3) array to solve the following problem: Write an application that inputs nine numbers, each of which is between 1 and 10, inclusive. Display the array after the user inputs each value. Rotate/flip the array by changing places. Make the rows columns and vice versa. You have to move the elements to their new locations. Remember to validate the input and display an error message if the user inputs invalid data. Documentation and the screenshot(s) of the results. Example: 1 2 3 4 5 6 7 8 9 the result will be : 1 4 7 2 5 8 3 6 9arrow_forwardpart a- 2point) for 3 students find the average of a student by asking him how many grades do you have. The answer to this question, determine the size of the array(list of grades) and then ask the user to enter grades(the number of the grades is equal to the size of the array) then calculate the average for each student. Hence, you will calculate 3 averages. to calculate the average, use the array accumulator. Also when you get each grade validate it. validation for grade means that you check whether a grade is between 0 and 100. if the grade is negative or a grade is more than 100 then it is not valid and you have to ask the user to enter a grade again. Part b- 1 point) Find the maximum and minimum grades for each student. Part c- 1 point) Print the sorted list of the grades for each student. example: if grades user entered are: 60 78 98 23 45 then sorted list is:23 45 60 78 98 (Array not vector)arrow_forward
