in java Create two arrays with same length n: - Array A with integer numbers that user will insert- Array B with random numbers from 0 to 100.- Find sum of both arrays,- Find maximum values of both array and compare them: .if maximum of 1 st is lower then maximum of 2nd array: print sums of both arrays.if maximum of 1st is greater then maximum of 2nd array print 2nd array (use println)otherwise print first array in reverse.
/*In this program you need to implement four methods with the following signatures:printArr(int[] a)add(int[] a, int[] b)subtract(int[] a, int[] b)negate(int[] a) 1. Method printArr(a) should print out all elements of a given int array in one line. 2. Method add(a, b) should take two int arrays (assume they have the same length) and return a new array each element of which will be the sum of the corresponding elements in a and b 3. Method subtract(a, b) is similar to add(), except it returns (a - b) array 4. Method negate(a)takes an int array and returns a new array in which every element is multiplied by -1. */ public class ArrayOperations{ public static void main(String[] args){ //The main only has the testing code. //You don't have to change it. int [] a = { 1, 2, 3, 4, 5}; int [] b = {10, 1, 3, 5, 7}; System.out.print("a = "); printArr(a);//Should print each element of a (in one line) System.out.print("b = ");…

Method Details: public static java.lang.String getArrayString(int[] array, char separator) Return a string where each array entry (except the last one) is followed by the specified separator. An empty string will be return if the array has no elements. Parameters: array - separator - Returns: stringThrows:java.lang.IllegalArgumentException - When a null array parameter is provided
Method Details getCountInRange public static int getCountInRange(int[] array, int lower, int upper) Returns the number of values in the range defined by lower (inclusive) and upper (inclusive) Parameters: array - integer array lower - lower limit upper - upper limit Returns: Number of values found Throws: java.lang.IllegalArgumentException - if array is null or lower is greater than upper Any error message is fine (e.g., "Invalid parameters(s)")
