- Write a program that creates and initializes an array with the following four values: 2.3, 4.5, 8.0, and 2.1. Use a for loop to print the array elements and then use a for loop to print the array elements in reverse order. Using java programmingTwo-Dimensional ArrayInstruction:Create a java program that generates elements (randomly from 10 – 75) of a 2-dimensional array (5x5) using the Random Class then perform the following: NOTE: Please do not use the array methods available on the internet. Use the for loop, while loop or do-while loop statement in your codes.Program this in java:a. I input an array of integers: int[] arr = { 4, 100, 2, 50, 7, -45, -23, 84, 51, 120, 98, -72 }.b. Declare an integer variable that named "total".c. create a loop.d.1. The loop control variable value to be declared is 0. This will be represented by the variable "i" and it represents the index of the inputted array.e.2. The loop has a condition that if the current loop control variable value is greater than or equal to the size of the array minus the first item of the array, the loop will break.f.3. After the body or function is executed, the loop control variable is incremented by 2.g.4. The body of the loop has a conditional statement. if arr[i] is even, add it to total, else minus it to the total.g. After the loop breaks or finishes, display the value of the total.
- Write a program in Java programming language that reads an array of strings! The program should write all the strings from array that end with letter 'a'.Nrite a program in Java that reads 10 integers and store them in AN ArrayList. Then, do the following: ) Print the ArrayList in the reverse order b) Sort the ArrayList, and display the data after sorting c) Print the largest and the smallest element in the ArrayListWrite an application that stores nine integers in an array. Display the integers from first tolast, and then display the integers from last to first.
- Write a program that creates and initializes an array with the following four values: 2.3, 4.5, 8.0, and 2.1. Use a for loop to print the array elements and then use a for loop to print the array elements in reverse order.Write the statement necessary to create an ArrayList of integers named numberList. this is needed in JavaHow to use for and foreach loops to display elements of an array? write code in java.
- JAVAWrite a program that searches person's name and display all matched name. For example, if a user inputs the letter "Davis", the program searches all name which includes "Davis" in an array. Then, display all matched names on the screen. You must declare a single dimensional array which has all people’s name. Use methods of string classComplete the following program ArrayMax.java. The function max() should return a new array containing the max value of each corresponding value in two arrays. Below is the code, with the section that needs to be completed. The output should look exactly like what is given below, alsoWrite this program in Java using a custom method. Implementation details You will implement this program in a specific way in order to gain some experience with loops, arrays and array lists. Use an array of strings to store the 4 strings listed in the description. Use a do-while loop for your 'game engine'. This means the game starts once the user enters money. The decision to stop occurs at the bottom of the loop. The do-while loop keeps going until the user quits, or there is no money left. The pseudocode for this 'game engine' is shown below: determine the fruits to display (step 3 below) and print them determine if there are 3 or 4 of the same image display the results update the customer balance as necessary prompt to play or quit continue loop if customer wants to play and there's money for another game. Use the Random class to generate a random number between 0 and 3. This random number will be an index into the array of strings. Add the string at that index to an…
