Write a program that draws a fixed rectangle centered at (100, 60) with width 100 and height 40. Whenever the mouse is moved, display the message indicating whether the mouse pointer is inside the rectangle, as shown in Figure 9.32. To detect whether the pointer is inside a rectangle, use theRectangle2D class defined in Exercise 8.19.
This is a debugging question -
The files provided in the code editor to the right contain syntax and/or logic errors. In each case, determine and fix the problem, remove all syntax and coding errors, and run the program to ensure it works properly.
This is the code that I have edited. I will attatch a screenshot of the two checks I am missing -
public abstract class DebugBoat
{
String boatType = new String();
int passengers;
String power = new String();
public void FebugBoat(String bt)
{
boatType = bt;
}
public boolean equals(DebugBoat otherBoat)
{
boolean result;
if((passengers == otherBoat.passengers) && (power.equals(otherBoat.power)))
result = true;
else
result = true;
return result;
}
public String toString()
{
return("This " + boatType + "boat carries " + passengers +
" and is powered by " + power);
}
abstract void setPower();
abstract void setPassengers();
}

The program should be well structured, and the taskperformed under each option (at least options 'b' to 'e') should be implementedas a separate method.NOTE: The Scanner class does not have a method to input a character. Inorder to read a character from the keyboard, use one of the following methods(after declaring the Scanner object):static Scanner kb = new Scanner(System.in);1. char ch = kb.nextLine().charAt(0); OR2. char ch = kb.nextLine().toLowerCase().charAt(0);where kb is a Scanner class object.The second method above also converts the input to lowercase, which is oftenuseful. Though these methods allow the user to input more than one characteron the input line, the rest of the line (after capturing the first character withcharAt(0)) is discarded.If you also want to ignore the leading spaces before the first character thenuse:1. char ch = kb.nextLine().trim().charAt(0); OR2. char ch =…arrow_forwardIN JAVA Trace the evaluation of the expressions and give the resulting values.

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.
