- Searching and sorting in Java programming: Write a method remove, that takes three parameters: an array of integers, the length of the array, and an integer, say removeItem. The method should find and delete the first occurrence of removeItem in the array. If the value does not exist or the array is empty, output an appropriate message. Note: after deleting the element, the array size is reduced by 1. You may assume that the array is unsorted. Thank you. I took Java in 2012 and 2013, and we didn't go too deep in this cocept..just a little bit in the Arrays chapter. i wanted to try something ne! Thank you!arrow_forwardWrite the following methodthat tests whether the array has four consecutive numbers with the same value:public static boolean isConsecutiveFour(int[] values)Write a test program that prompts the user to enter a series of integers and displaysit if the series contains four consecutive numbers with the same value. Yourprogram should first prompt the user to enter the input size—i.e., the number ofvalues in the series. Here are sample runs: Enter the number of values: 8↵EnterEnter the values: 3 4 5 5 5 5 4 5↵EnterThe list has consecutive foursEnter the number of values: 9↵EnterEnter the values: 3 4 5 5 6 5 5 4 5↵EnterThe list has no consecutive foursarrow_forwardJava programming Write a method that takes an array of integers as a parameter. The method should return the occurrence of the even numbers in the passed arrayarrow_forward
- A bit new to methods and need a little bit of help. Swap Method Your task is to write a public static method named swap that takes a single parameter which is an array of doubles. This method should swap the first and last element in the array and then return the adjusted double array. You can assume that all arrays passed into the method are a length of 2 or more. For example, the test data provided when passed into the swap method should go from: {8.34, 7.221, 10.643, 93.2} toarrow_forwardPseudocode for Java code Write the algorithm in pseudocode for a method that accepts three parameters: an integer array, an integer representing the number of valid values in the array, and an integer representing a factor. The method will count the number of valid values in the array that are multiples of the factor and will return the count. There is a Java operator that might be very helpful in solving this problem. Testing Above problem: Assuming that the first two parameters are an array containing 4, 10, 15, 12, 8, 20, 100, 25, 32, 7, 28, and 48 and the number 12, come up with three good test cases for the factor and the return value. factor numMultiplesarrow_forward1. Shift Left k Cells Use Python Consider an array named source. Write a method/function named shiftLeft( source, k) that shifts all the elements of the source array to the left by 'k' positions. You must execute the method by passing an array and number of cells to be shifted. After calling the method, print the array to show whether the elements have been shifted properly. Example: source=[10,20,30,40,50,60] shiftLeft(source,3) After calling shiftLeft(source,3), printing the array should give the output as: [ 40, 50, 60, 0, 0, 0 ]arrow_forward
- java plz solve asaparrow_forwardMultiple Frequencies. In the last assignment, we calculated the frequency ofa coin flip. This required us to have two separate variables, which we used to record the numberof heads and tails. Now that we know about arrays, we can track the frequency of all numbers ina 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 numberof 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 thenumber sequence, and another could keep track of the frequencies of each number.Sample Output #1:What’s the highest number you want to generate?: 5How long of a number sequence do you want to generate?: 10Okay, we’ll generate 10 number(s) ranging from 1 to 5!1,…arrow_forwardProgramming in C language. RandomNumbers Declare an integer array locally with the size of 200. Create a program that asks the user how many numbers the have. Use your getChoicel) function from before. Make sure it does not exceed 200 as the locally declared array has the size of 200. Use a loop to assign random numbers from 1 to 10000 to the array elements. (Remember to use srand() to seed the random number generator). Use a second loop to display each number, and also determine the average of all values in the array. You must also find the largest and the smallest numbers. After the for loop, display the average of all numbers. This program will let you enter a list of numbers into an array. It will then display all of the numbers, and finally display the average of all numbers. How many numbers would you like to enter?10 Number 1 is 42 Number 2 is 8468 Number 3 is 6335 Number 4 is 6501 umber 5 is 9170 Number 6 is 5725 Number 7 is 1479 Number 8 is 9359 Number 9 is 6963 Number 10 is…arrow_forward
- For the array ADT, the operations associated with the type array are: insert a value in the array, delete a value from the array, and test whether a value is in the array or not. 1.true 2.falsearrow_forwardPython Programming: Sergey is suffering from a unique brain disease where his brain can only process odd digits. He is performing a task where he has to get the gcd of given numbers in an array. Your task is to write a code which will make sure that the gcd of numbers present in array is odd. You can consider a particular index ore than one time if needed. Your code should return the minimum number of tries after which gcd becomes odd. Input Output 1 1 4 2 64 12 18arrow_forwardTableAA.java Write a program that will store a multiplication table in a 2-D array. The user will enter how many lines (rows) it will have. The table will be printed to the screen. (Make it look nice – consider using printf.) This program will contain a static method. This method will take in an integer (the user’s number) and it will return a 2-D array. The code inside of the method will create the array, fill it with all the appropriate values that one would expect in a multiplication table, and then return that filled array. In the main method, you will ask the user how many lines they want to see and then you will use your static method to get the array. Once you have the array back from the static method, use nested for loops to print it in table form. See samples on the following pages. Program only needs to run once. Add try/catches so the user can only enter positive integers (1 and higher).arrow_forward
