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 100Write a java program: Question 1 Write a program that allows the user to enter name and grade until "QUIT" is entered for name. The grade should be a number between 0 and 100. If the user input of a grade is not in this range, you should ask the user to re-input the grade. Store all the names in an array called names, and all the grades in an array called grades. Print out all the names and the corresponding grades. For Example, Input Enter name: Alice Enter grade: 90 Enter name: Bob Enter grade: 80 QUIT Expected output Name: Alice, Grade: 90 Name: Bob, Grade: 80
- Write a Java method that reverses a given array. the method that reverses the array passed in the argument and returns this array. Write a test program that prompts the user to enter ten numbers, invokes the method to reverse the numbers, and displays the numbers.1. Write a java program with only the main() method that will print out following pattern.Use nested for loops, no input required from the user.55 45 4 35 4 3 25 4 3 2 12. Add to your java program from #1 above, that asks the user to enter an array of integersin the main() method. The program will first ask the user for the number of integerelements, how many, to be inputted into the array, and then ask the user for each elementof the array. Next, build a new method named isSorted() that accepts an array ofintegers and returns true if the list is in sorted in increasing order and false otherwise.For example, if arrays named arr1 and arr2 store [10, 20, 30, 41, 56] and [2,5, 3, 12, 10] respectively, the calls isSorted(arr1) and isSorted(arr2) shouldreturn true and false respectively. Assume the array has at least one integer element.A one-element array is considered to be sorted.Write a java program, I believe the first array should only be changed. In the main method: Create an array with the values: 99, 55, 87, 21, 3, using any method Create a second array Copy the elements of the first array to the second Change an element of the first array. Print both arrays
- Write a Java program to print true if the sum of all the 2's in the array is exactly 8. You can assume the array by your own.Write a Java method that returns the location of the largest element in a two-dimensional array. public static int[] locatelargest (double[][] a) The return value is a one-dimensional array that contains two elements. These two elements indicate the row and column indices of the largest element in the two-dimensional array. Write a Java test Program that prompts the user to enter a two- dimensional array and displays the location of the largest element in the array. Here is a sample run: Enter the number of rows and columns of the array: 3 4 Enter Enter the array: 23.5 35 2 10 |- Enter 4.5 3 45 3.5 -Enter 35 44 5.5 9.6 Enter The location of the largest element is at (1, 2)Write a Java program (One class with a main method) to do the following: 1. Ask the user to enter an integer (n) 2. Declare an array of size n with integer data type. 3. Ask the user to enter the values of the array. 4. Create another array with of size n with integer data type. 5. Make a copy of the first array to the second array but in reverse order (e.g., the last element in the first array should be store in the first element in the second array and so on). 6. Output values stored in the two arrays. 7. Find and output how many values in both arrays are equal based on the index number, i.e. count matching values of two arrays based on same index value AND the element value of the array. Sample Input/output Enter n:4 Enter array values: 1234 First Array :1 234 Second Array:4 321 # of Equal values = 0 Enter n:5 I Enter array values: 12345 First Array :1 2345 Second Array:5 4321 # of Equal values = 1
