Return its contents as a String. If you look in the file MathVector.java you'll see there is a way to output the contents of a MathVector object as a String. This makes it useful for displaying to the user. You might have noticed that there's an @override term there. That's because many objects already have a "toString()" method associated with them... because Java was designed to include them by default. Here, the override tells Java "I know, I know. You already have a toString() that you'd assign here. But it's not good enough. Here's a better one for this particular kind of object." It's a little bit like saying "Most humans have two legs. So, by default, I'll give everyone two legs. But sometimes we override that and give no legs, or just one leg to a person. And sometimes we give them four so that they can be a centaur!" To use this in a println() method, just name your object. The toString()…Please read the instructions carefully and keep in mind of the bolded phrases.

- How do I create in Java create a public static method named manipulateString that asks the user for a sentence using the Scanner. Use the String class’s split method to split the text into an array of Strings using “ “ (space) as the delimiter. Print the words of the sentence in reverse order. The words at odd indexes prior to the reversal should have all their characters converted to lowercase. The words at even indexes prior to the reversal should have all their characters converted to uppercase. Example Run1: Enter a sentence: User enters: “Now is the time for all good programmers to come to the aid of their country!” Method prints: “country! THEIR of AID the TO come TO programmers GOOD all FOR time THE is NOW” Example Run2: Enter a sentence: User enters: “an apple a day keeps the doctor away" Method prints: “away DOCTOR the KEEPS day A apple AN"On line 47, I am trying to create a method that which takes a String parameter and updates the arrayfor the user.

- In java Start with the file AList.java and add the following methods: Add the method public int getLastIndex(T item) which returns the index of the last entry which is equal to item. If item is not found, it returns -1. Add the method public int removeEvery(T item) that removes all occurrences of item and returns the number of removed items. Add the method public boolean equals(Object other) that returns true when the contents of 2 AList objects are the same. Note that 2 AList objects are the same if they have the same number of items and each item in one object is equal to the item in its corresponding location in the other objectModify the NumbersDemo application whose main() method holds two integer variables. Assign values to the variables. In turn, pass each value to methods named displayTwiceTheNumber(), displayNumberPlusFive(), and displayNumberSquared(). Create each method to perform the task its name implies. public class NumbersDemo { public static void main (String args[]) { // Write your code here } public static void displayTwiceTheNumber(int n) { // Write your code here } public static void displayNumberPlusFive(int n) { // Write your code here } public static void displayNumberSquared(int n) { // Write your code here } }When testing this java program I get a java.lang.NullPointerException for 3 sections of the function, specifically String remove, String reverse and String filterLetters
