- we are going to create a new subclass of the SimpleGeometricObject class, namedTriangle. Copy the source code of the SimpleGeometricObject class from the following link: https://liveexample.pearsoncmg.com/html/SimpleGeometricObject.html TASK 1: Create a Triangle class that extends the SimpleGeometricObject class in Eclipse, followingthe below UML diagram. Use the following formula to calculate the area of a triangle: A = 1/2 × base × height TASK 2: Create a TestTriangle class in an individual .java file. In the main method,(1) Create a Triangle object with default base and height values.(2) Create a Triangle object with specified base = 3 and height =4. TASK 3: Add a toString() method to the Triangle class. In this toString() method,(1) Print the base, height, and area of a Triangle object.(2) Call the toString() method of the superclass using the super key word.Then, in the main method of the TestTriangle class, make the two Triangle objects that youcreated in Task 2…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 sequencePrint the integers to the command line, using a for loop, so that each integer is on a separate lineNeed it asap please !!!

The Java application should consist of a graphical user interface that can be used to add elements to the LinkedHashMap. There should be two TextFields to take in the element name and number. Then there should be four buttons to do four tasks, namely: add, change, remove and show all elements in the LinkedHashMap. Your buttons should have Action methods and should make use of methods in the LinkedHashMap class.When the Add button is clicked, the element name and value should be added to the LinkedHashMap. Make use of the LinkedHashMap methods to add the elements. When the user fills in the element name and number and the Add button is clicked, a message should be displayed in an alert dialog box to the user to inform them of this If no element is specified at the time the Add button is clicked, an error message should be displayed to inform the user to enter the element

Add a new method for the interface bicycle: ring the bell with a parameter indicating how many time. Pick a bicycle brand and create a new class of bicycles for that brand, as described in the sections What is an interface? and What is a Class? For the new method implementation, write in the console "Clang! Clang!..." for how many times the parameter indicates. Create another class, with a main method, in which you will take a trip aroound your house, changing your bicycle attributes, starting and ending from a complete stop, and ringing the bell once at start and twice at the end. Use as inspiration the method in What is a Class? Your trip must have at least 5 different parts in which you change your bicycle…
