Step by step
Solved in 2 steps
- 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,-2Write 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.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]…
- Consider the following code: int a[5] = {1,3,5,7,9};int b = a[3]; // <--- here Rewrite the last statement (marked “here”) without using array brackets [ ]. Group of answer choices int b = a + 3; int b = *(a + 3); int b = *a + 3; int b = *(a + 2);I need this program in java please. #Given Arrayarray=[1,1,1,2,2,2,2,2,4,5,5,6,6,6] #Insert valuevalue=3 index=0for x in array: if value<x: #inserting to the array in the position index array.insert(index,value) print ("Output :",array) break #Incrementing position by 1 index=index+1*IN JAVA PLEASE* 2)For this exercise, you are given an array of integers. Return true if every element in the array is an odd number, otherwise return false. 3) Given an array of strings, return the array in reverse order. For example, given: reverse({"one", "two", "three"}); You would return: {"three", "two", "one"} 4) For this exercise, you need to shift all the elements in the array one space to the right (increase the index of the element by 1). The last element will wrap around and become the new first element. For example, given: moveUp({"first", "second", "third", "fourth"}); You would return: {"fourth", "first", "second", "third"}
- Q1: Write a program in Java that reads 10 integers and store them in AN ArrayList. Then, do the following : a) Print the ArrayList in the reverse order b) Sort the ArrayList, and display the data after sorting c) Print the largest and the smallest element in the ArrayListFirst, write a Java method isSequence that takes as parameters a non-empty 2-dimensional array of integers. The method checks whether the elements of the array are consecutive or not.Second, write a java methods printArray(int[][]a) that writes the elements of an array passed in parameter to the standard output.Finally, use the following main method to test your different methods:Can help in java ? Define a two-dimensional array of names. For each row: • specify the name with the longest length • check for a name starting with "A" (save its index) Save the results in one-dimensional arrays (initialize all elements of the second result array with -1 initially). Display an array of names, the names with the longest length of each line, and the name starting with "A" from each line or a message that there is none.
- Answer the given question with a proper explanation and step-by-step solution. In Java, please. Consider the following problem. Input: an array of integers A[] Output: rearranges the array to have the following property: Suppose the first element in the original array A[], A[0] = x. In the rearranged array, suppose that x is at index i, that is A[i] = x. Then, we want the rearranged array to be such that A[j] <= x for all j < i and A[j] > x for all j > i. The rearranging should place all the values less than (or equal to) x to the "left" of x and all values larger than x to the right of x. Here's an example. Suppose the array has the elements in this initial order: 4 3 9 2 7 6 5 A[0] = 4. After rearranging elements, we get: 3 2 4 5 9 7 6 That is, A[0] = 4, is positioned in the resulting array so that all elements less than 4 (that is, 2, 3) are to its left (in no particular order), and all elements larger than 4 are to its right (again, in no particular order).I am trying to write a code that swaps 1st element of an array with 2nd one, 3rd with 4th and keeps like that. It is not working and instead I wrote a code that is reversing the order. (better explanation on pictures attached.) I am using Java. public static void swapPairs(String[]array) {for(int i= 0; i< array.length / 2; i++) {int j= array.length - i -1;swap(array, i, j);}}public static void swap(String[] array, int i, int j) {String temp= array[i];array[i]= array[j];array[j]= temp;}Machine Problem #7. Using the concept ArrayList, write a method-oriented Java program that will take 10integer inputs from user and print the following: number of positive numbers, number of negative numbers,number of odd numbers, number of even numbers, number of 0s. Note: 0 is not considered a positive number.ClassName: MethodArrayListArraySearchSample Input/OutputEnter values of the Array List-9-81005608-1214Number of positive numbers: 7Number of negative numbers: 3Number of odd numbers:2Number of even numbers: 6Number of 0s: 2Machine Problem #8.
