Write a java code for the following. Write two methods that return the union and intersection of two arrays of integers using the following header: public int [ ] union(int arr1[ ], int arr2[ ] ) public int [ ] intersection(int arr1[ ], int arr2[ ]) For example, the union of two array lists {2, 3, 1, 5} and {3, 4, 6} is {2, 3, 1, 5, 3, 4, 6} and intersection is {3}. Write a test program that prompts the user to enter two lists of size 4 each, and displays their union and intersection. The numbers are separated by exactly one space in the output.
Consider the following array: int a[ ] = {1, 2, 3, 4, 5, 6, 7, 8, 9, 0}; What is the value of total after the following loops complete? int total = 0; for (int i = 0; i < 10; i++) { total = total + a[i];} int total = 0; for (int i = 0; i < 10; i=i+2) { total = total + a[i];} int total = 0; for (int i = 1; i < 10; i=i+2) { total = total + a[i];} int total = 0; for (int i = 2; i <= 10; i++) { total = total + a[i];} int total = 0; for (int i = 0; i < 10; i=2 * i) { total = total + a[i];} int total = 0; for (int i = 9; i >= 0; i--) { total = total + a[i];} int total = 0; for (int i = 9; i >= 0; i=i - 2) { total = total + a[i];} int total = 0; for (int i = 0; i < 10; i++) { total = a[i] – total;} what are the values in c++

In Java Write an application that inputs five numbers, each between 10 and 100, inclusive. As each number is read, display it only if it’s not a duplicate of a number already read. Provide for the “worst case,” in which all five numbers are different. Use the smallest possible array to solve this problem. Display the complete set of unique values input after the user enters each new value. Rough output in screenshot
(IN JAVA) Write a method which does the following: Ask the user to enter a size of array between 2 to 10. Based on the size entered, write a loop which asks the user to fill values into an integer array. Print the array contents using Arrays.toString(). For this integer array, write a logic that returns true if there exists a place to split the array such that the sum of the numbers on one side is equal to the sum of the numbers on the other. Otherwise return false. Examples: If the array is {1, 1, 1, 2, 1} then return true. If the array is {2, 1, 1, 2, 1} then return false If the array is {10, 10} then return true.
(in Java language) Write a method that is inspired by a photo app that does the following. Ask the user to enter a size of array between 2 to 10. Based on the size entered, write a loop which asks the user to fill values into an integer array. Print the array contents using Arrays.toString(). For this integer array, write a logic that returns true if there exists a place to split the array such that the sum of the numbers on one side is equal to the sum of the numbers on the other. Otherwise return false. Examples: If the array is {1, 1, 1, 2, 1} then return true. If the array is {2, 1, 1, 2, 1} then return false If the array is {10, 10} then return true.
(d). Change the value of the very last array element of the 2D array int_arr to 10.(e). Change the value of the very first array element of the 2D array int_arr to 10(f).

Write a Java for loop to print every array element in the last column. i have this so far int int_arr[][] = new int int_arr[5][7]; # Initialize a 2D array of size 3x4 with zerosint_arr = [[0 for j in range(4)] for i in range(3)] # Assign i*j to each element in the arrayfor i in range(len(int_arr)): for j in range(len(int_arr[i])): int_arr[i][j] = i*j # Change the value of the last array element in row 0 to 5int_arr[0][-1] = 5 # Print the resulting arrayfor row in int_arr: print(row)
Complete the following method in java that takes an array and a key(int value) that traverses the input parameter array with a nested for loop and finds the number of pairs of the numbers in the array that add up to the val(key) parameter. I'm not sure if this is correct: public static int nestedLoopsTwoSum(int[] X, int val) {int count = 0;for (int i = 0; i < X.length; i++){int k;for (k = 0; k < i ; k++){if ((X[i] + X[k]) == val){count++;}}}return count;}
