JAVA Chapter 9 Multidimensional Arrays and the ArrayList Class Write a value returning method that returns the sum of the elements in the last column of each row in a two-dimensional array of ints. Include code to test your method.

Task 2: Write a static method which takes an ArrayList of Strings and an integer and changes the ArrayList destructively to remove all Strings whose length is less than the integer argument.

Intellij - Java Write a program which does the following: Create a class with the main() method. Take a string array input from the user in main() method. Note: Do not hardcode the string array in code. After the String array input loop, the array should be: words[] = {"today", "is", "a", "lovely", "spring","day", "not", "too", "hot", "not", "too", "cold"}; Print the contents of this array using Arrays.toString() method. Write a method called handleString() that performs the following: Takes a String[] array as method parameter (similar to main method). Loop through the array passed as parameter, and for each word in the array: If the length of the word is even, get the index of the last letter & print that index. Use length() and indexOf() String object methods. If the string length is odd, get the character at the 1st position in the string & print that letter. Use length() and charAt() String object methods.

Write a call to Arrays static method equals with arguments arrayl and array2.

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");

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
