(Java) 7.2 Code: Look at the following Person.java class code: class Person{public String name;public int age;public String gender;public void greeting() {System.out.println( "Hi, my name is " + name + "!");}public void greeting(String otherName){System.out.println("Hi, " + otherName + "!");}public void printPerson () {System.out.println("Name: "+name);System.out.println("Age: "+age);System.out.println("Gender: "+gender);System.out.println();}} Remove the printPerson method from this class. Instead, write a toString() method that can be used to display the Student Object in the following manner: Name: <The Name> Age: <The Age> Gender: <The Gender> Note the use of the <> above. Do not add these <> to your String. Instead, these <> are commonly used to mean a value will be filled in later. Don't forget the @Override tag in front of the toString() method image source Using the below starter code and the toString method, we will…

Please help me solve this with java .... just the HangMan HangMan instruction class : • HangMan is a game in which a player tries to guess a word based on a given hint. For example, if the given hint is “movie”, then the player must guess a movie name. If the given hint is a “country”, then the player must guess a country name, and so on.• The game starts by showing a message on the screen that shows the hint and all letters in the word but obscured as dashes (-). Then, the game will allow the player to guess 5 letters. If the player gives a letter that actually exists in the word, then this letter will be revealed. Afterwards, the game will ask the player to give the answer. If the given answer is correct, then the game will show a message that the player has won 5 points. Otherwise, the game will show a message that the player has lost. Below is one possible game scenario, in which the word is “iron man”, and the hint is “movie”. Note that the text in green color is the…
