Write in java 1. Write a program that calls these two methods as described below a. A void method that prints following pattern (Pay attention to the space in between the characters) 5 54 543 5432 54321 b. A void method that creates an integer array of size 12. The method then ask the user to input these 12 numbers and store them in the array. Then print out the positions of all the even integers. Then print out the positions of all the odd integers. Example: Input a number (1/12): 3 Input a number (2/12): 5 Input a number (3/12): 7 Input a number (4/12): | Input a number (5/12): 2 Input a number (6/12): 3 Input a number (7/12): 10 Input a number (8/12): 6 Input a number (9/12): 2 Input a number (10/12):7 Input a number (11/12): 12 Input a number (12/12): 9

QUESTION 2 Write a Java program to input a single dimensional integer array of size 8. Pass the array to a method named countBigNumbers that return integer. In this method, count the array elements that are bigger than 50 and place them in another array. Display the returned count in main method. Display the two arrays by invoking a method named displayArray. 2 Sample inputs and their outputs are shown below: Input 8 numbers: 5 60 8 99 1 100 7 51 Count of numbers bigger than 50 is 4 Array1 is 5 60 100 51 66 Array2 is 60 99 100 51 Input 8 numbers: 80 19 91 150 37 23 50 49 Count of numbers bigger than 50 is 3 Arrayl is 80 19 91 100 37 23 50 49 Array2 is 80 91 100

You are given an array of n integers. Write a java method that splits the numbers of the array into two equal groups so that the GCD of all numbers in the first group is equal to one and the GCD of all numbers in the second group is not one. After splitting the numbers display the resulting groups as shown in the sample run below. Note: 1. The array has even size. 2. All elements of the array are less than 100. 3. You can define at most only one one-dimensional array. Sample run of the method: Input array: {6,7,9,4,3,2} Output Group one : {7,9,3} //Ignore Order of numbers. Order is not important Group two: {2,4,6} //Ignore Order of numbers. Order is not important
Write a Java program to make two arrays containing random integer values (You can make these arrays with specific sizes using the below makeRandomArray method). The program should sum these two arrays and prints the resulted array (the array that contains the result of the two arrays summing). The program should also show the maximum element of the resulted array. Your program must define and call the following methods to perform the program as illustrated above: A method int [] makeRandomArray(int size ,int a , int b) that makes and returns an array with specific size. The methods fills this array with random integers in a range [a..b] A method public static int findmax(int x[ ]) that finds the maximum value of a number of x array passed to the method. A method public static void printArray(int x[ ]) that prints the elements of the array x passed to the method. A method public int[ ] sumTwoArrays(int x[ ], int y[ ]) that sums the elements of the two arrays(x and y arrays) and puts…
PLEASE HELP ME WITH MY JAVA HOMEWORK PLEASE PLEASE! Write a program that stores positive random integers in an array. • Get the element number(length of the array) from the user. It cannot be less than 10. And fill this array andomly. The range is up to you. No duplicate values are allowed. Display the elements. • Your job is to write a method that finds and returns the next biggest positive integer considering the biggest element in this array. • Show me your main method too. DO NOT USE ANY PRE_DEFINED METHODS IN THE JAVA API.
