What is the difference between equals() and == ? == looks to see if they are identical objects whereas equals() matches the content of the objects. equals() looks to see if they are identical objects whereas == matches the content of the objects. equals() and | == are used to match the content of objects, so no difference. equals() is used to match string objects whereas == is used to match all objects. 0 000

- Create a code that tracks how many times a phrase appears in a string. A number should be the function's output value. Never presume that a series of words can contain punctuation and only one space between words. Create the method so that it accepts a String argument or a StringBuilder object as a parameter.Create a function that tallies the number of times a phrase appears in a string. The function's output should be a number. Don't presume that a single space divides words, and that a string can contain punctuation. Create the method so that it can accept a String input or a StringBuilder object.Button Toggle How can we make a button that toggles a text view (not the button label) between "Howdy Class!" and "You Pressed Me!"? Please write the java onClick function that would be specified in the button onClick property. Do not use string comparison to determine the current state. Also, do not use hard code string values.
- Create two linkedBag objects of type string in main. Place 5 strings in the first bag and five strings in the second bag. Then your code must test if the two linkedBag objects are equal or not. You must traverse both linkedBags and test each items to see if they are the same. Then you must display a message saying the two linkedBags are the same or different. Using Java compiler.In some cases, a class depends on itself. That is, an object of one class interactswith another object of the same class. To accomplish this, a method of the classmay accept as a parameter an object of the same class.The concat method of the String class is an example of this situation. Themethod is executed through one String object and is passed another String object as a parameter. Here is an example:str3 = str1.concat(str2);The String object executing the method (str1) appends its characters to thoseof the String passed as a parameter (str2). A new String object is returned asa result and stored as str3. Write java code to implement given conditionsIn the below example, how many String Objects are created?
- Description is " A MathVector object will be passed to your method. 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()…Submission Instructions Follow the instructions for How to Submit Programming Assignments. Assignment First, launch NetBeans and close any previous projects that may be open (at the top menu go to File ==> Close All Projects). Then create a new Java application called "Parser" (without the quotation marks) that uses methods to: Get a comma-delimited String of integers (e.g. "4, 8, 16, 32") from the user at the command line and then convert the String to an ArrayList of integers (using the wrapper class) with each element containing one of the input integers in sequence Print the integers to the command line, using a for loop, so that each integer is on a separate line BE SURE TO INCLUDE THE REQUIRED COMMENTS AND DOCUMENTATION AS WELL AS THE OUTPUT FROM MULTIPLE PROGRAM RUNS AS A COMMENT BLOCK AT THE BOTTOM OF YOUR SOURCE CODE FILE. See Grading Rubric.Create class that performs different functions on Strings that are sent to it. All the methods you create will be static. Only two methods (mentioned below) and the main method need to be public. Any other methods that you write to help these methods should be private because they are only used internally within the class. Requirements: 1. Prompt users to enter 3 string inputs. Consider strings with alphabetic characters (a - z, A - Z) and/or numbers (0 - 9) as valid. Strings contain only non-word characters are invalid. Print the following usage when an input string is invalid or is empty. Usage: Enter a string that contains alphabetic characters and numbers 2. Create a method "isPalindrome" that takes a String as a parameter and returns true if the given String parameter is a palindrome and false if it is not. In your main method, this method should be call with the first user input and print either "The given string is a palindrome." or "The given string is not a palindrome." as…
- A class plays a fishing game in which a large tub is filled with plastic fish that are identical, except that some are red and the rest are white. A student is blindfolded and pulls 10 fish out of the tub. The student removes the blindfold, writes down how many of each color fish she got, and then puts the fish back in the tub. Each student takes a turn. The results are shown in the table. Display these data in a dot plot. Write and answer (to the extent possible) at least three questions about the data display in part (a); include at least one question at each of the three graph-reading levels discussed in the reading.Pattern and Value are two strings that you must use. The pattern string, which denotes a pattern inside a string, is made up just of the letters a and b. For instance, the string catcatgocatgo matches the pattern aabab (where cat is represented by letter A and go by letter B). Additionally, it matches a, ab, and b pattern. To check whether a value matches a pattern, create a method.Question (1): Define the ReplaceAll method, its idea to search for partial text (word or phrase) specific and switch to another part. When you call the method, we must pass three texts. The first represents a plain text, the second represents the partial that we want to search for, and the third represents the partial that we want to replace with the second partial place. If the user click enter without writing a string, the program shows a message “There is no text!". See examples to get the idea. [5 Marks] Ехample 1: Enter your text: I am learning C++. I am writing C++ code. I like C++. Enter the word you want to replace: C++ Enter the word you want to replace with: Java Before: I am learning C++. I am writing C++ code. I like C++. After: I am learning Java. I am writing Java code. I like Java. Ехample 2: Enter your text: There is no text!
