Can help in java String [] names = {"Dimo Ivanov", "Yani Yanev", "Ana Popova", "Nelly Angelova"}; 1. Display the array in the console using the Arrays.toString () method 2. Display the names and the number of characters in the name (without the space) as a table (use printf) Name Number of lettersDimo Ivanov 10 3. Get an array first_letters of type char [], containing the first letters of the names. Display it with Arrays.toString () 4. Get the arrays of names and surnames containing initial and second names, respectively (first determine the position of the space in the previous name with the indexOf () method of the String class). Display the arrays. 5. Sort the first_names array
Answer both otherwise I’ll mark downvote and bad review too
Please send me answer of this question immediately and i will give you like sure sir
1. Write a program that fills an array with 10 random integer values between O and 100, your program should then calculate and print the alternating sum of all elements in the array. for example, if the array values are (89, 35, 44, 61, 66, 52, 45, 16, 48, 73) then the sum will = 89- 35 + 44 - 61 + 66- 52 + 45 - 16 + 48 - 73 = 55. Sample Run: The generated numbers are: 2 11 44 38 66 72 38 67 43 13 The alternating sum is -8 2. Write a program that reads 10 characters from user and store them in an array. Then display one or more of the following messages: 1. All characters are letters 2. All letters in the list are upper 3. There is no vowel letter in the list 4. There is at least 2 digits in the list 5. There is at least 3 symbols in the list Sample run 1: Enter 10 characters: AB1OK8 M& ? All letters in the list are upper There is at least 2 digits in the list There is at least 3 symbols in the list
Using methods and arrays , write a program that Creates and fills an array A of size 50 filled with random integers in the range 5 to 50 inclusive . prints it out in 5 lines ( 10 values per line ) . • Calculates the sum of the odd elements of A and print it out .
Program: Using a multidimensional array, create a triangular-shaped array. You will ask the user how many lines they want to see and then create the array, fill it, and then print it. You will fill the array with one 1 in the first row, two 2’s in the second row, etc. This should work for any integer that the user enters. (Just because I am starting on 1 does not mean row 0 was skipped.) You must: use a loop to create the array shape. You must: use nested for loops to fill the array and to print the values back to the screen. Your program should print as shown below. Example Output: How many lines would you like in your triangle? >>>9 1 2 2 3 3 3 4 4 4 4 5 5 5 5 5 6 6 6 6 6 6 7 7 7 7 7 7 7 8 8 8 8 8 8 8 8 9 9 9 9 9 9 9 9 9 If your code looks like the code below, it is not what I’m asking for. The code below is making a square multidimensional array, not a triangular one. The code below is just leaving certain spots empty so that it looks like a triangle. I will ask you…
1. Code a method that will read in values from the user. 2. Add the following:  Allow the user to enter any number of positive integers  Store them in an array or array list  Let the user enter -1 to end their list of values.  Add error checking to make sure they enter positive values or a -1.
What is the solution for this question ( using java language)
Ask the user to enter an integer (n)Declare an array of size n with double data type.Ask the user to enter the values of the array.Create another array with of size n with integer data type.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).Output values stored in the two arrays.Find and output how many odd 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/outputEnter n:4Enter array values:1 2 3 4First Array :1 2 3 4 Second Array:4 3 2 1 # of Equal values = 0Enter n:5Enter array values:1 2 3 4 5First Array :1 2 3 4 5 Second Array:5 4 3 2 1 # of Equal values = 1

The Lo Shu Magic Square is a grid with 3 rows and 3 columns shown below. The Lo Shu Magic Square has the following properties: The grid contains the numbers 1 – 9 exactly The sum of each row, each column and each diagonal all add up to the same number. This is shown below: Write a program that simulates a magic square using 3 one dimensional parallel arrays of integer type. Do not use two-dimensional array. Each one the arrays corresponds to a row of the magic square. The program asks the user to enter the values of the magic square row by row and informs the user if the grid is a magic square or not. Processing Requirements - c++ Use the following template to start your project: #include<iostream> using namespace std; // Global constants const int ROWS = 3; // The number of rows in the array const int COLS = 3; // The number of columns in the array const int MIN = 1; // The value of the smallest number const int MAX = 9; // The value of the largest number //…
