2. Write a method that takes a rectangular two-dimensional array of type int and returns a valu of type int. The method returns the number of rows with negative sum. A row has a negative s if the sum of all its elements is less than 0. public static int countNegativeSum (int[][] in) Taken array Result -5 -3 17 -5 -2 30 -19 | -8| -8 1 -5 14 3 -1 -4 78 -3 -5 -1

1. Write a program that calls a method that takes a character array as a parameter (you can initialize an array in the main method) and returns the number of vowels in the array. Partial program is given below. public class CountVowels{ public static void main(String[] args){ char[] arr= System.out.print("There are "+vowels(arr)+" vowels in the array");
The programming language used is Java
Methods Details: public static java.lang.StringBuffer[] getArrayStringsLongerThan(java.lang.StringBuffer[] array, int length) Returns a StringBuffer array with COPIES of StringBuffer objects in the array parameter that have a length greater than the length parameter. If no strings are found an empty array will be returned. Parameters: array - length - Returns: Throws:java.lang.IllegalArgumentException - When a null array parameter is provided
Write a method that takes a rectangular two-dimensional array of type int. The method returns true if the sum of the even elements of the parameter array are larger than the sum of the odd elements, otherwise the method returns false. public static boolean sum(int[]0 in) Taken array Result 1 -3 17 5 -2 30 true 1 3 -1 -1 -3 -4 7 -1 10 false -1 3 -4 15
In JAVA Write the method below: Given a two-dimensional array containing integers, create a method called "matrixOperations" The method should do the following:1. Print out all the numbers in the array row by row (add empty line at the end of the row)2. For each row, print out the length of the row (each row is an array, remember)
