- Can you help with the following question? Write a Java program that creates and initializes an array of integers. Then it finds and prints theminimum odd value in this array with its index. Assume that all the values < 1,000,000.Your Friendly Array Neighbor Program only in java not in python Create a Java program that takes an array called ar as an input that keeps track of arrays. Every day a new array is produced using the array of the previous day. On the n’th day, the following operations are performed on the array of day n – 1 to produce the array of day n: -If an element is smaller than both left and right neighbor, then this element is incremented -If an element is bigger than both its left neighbor and its right neighbor, then this element is decremented. -The first and last elements should never change Eventually after some days the array will not change, some examples: Example: Input from user: ar = [6,2,3,4] Output from program: [6,3,3,4] After the first day the array is changed from [6,2,3,4] to [6,3,3,4] and no further operations may be completed. Example: Input from user: ar = [1,6,3,4,3,5] Output from program: [1,4,4,4,4,5] After the first day the array is changed from [1,6,3,4,3,5]…1. When you are taking java, you are aware that a[] is an array, It can also be evalutated under certain circumstances. if you have x[2*z+4], what do you need to be true to evaluate? a. 3<= x < z.length b. 3<= x < (z.length-1)/2 c 2 <= x < z.length d. 4<= x < z.length/2 2. Given the program solve the problem for (int i=0; i ! lolma.length-1; i= i+1){ lolma[i] = lolma[i]+lolma[i+1] the array looks like from 0-3: 5, 9, 1, -3 What will be the next order a. 5,9,1,-3 b. 11,19,3,-5 c. 14,10,-2,-3 d. 5, 14,10,-2
- 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.Can help in java ? Define a two-dimensional array of names.
