Java, some questions about to write the code.

Hi, I would like to have more marks for these questions compared to my answers.

Any help would be appriciated, Thank you.

Question 3 (File I/O) Total: 20 marks Write a Java class called ReadAndPrintScores that has a main method that opens a file called scores.dat, which contains a series of integers (i.e. scores) that are separated by a blank space. Your program should print the scores read to the console, one on each line. It should also catch and handle a FileNotFoundException by printing the error message to the console in the case where scores.dat is not in the current directory from where your program is run. Question 4 (Class) Total: 20 marks/ Write a public Java class called Point2d that has the following specifications: two private attributes, both decimal, called x and y. three constructors: (i) accepts two arguments and sets x and y to the value of these arguments; (ii) a default constructor that sets both x and y to 0.0; and (iii) a copy constructor that accepts a Point2d object as the only argument. has a pair of accessor and mutator methods for each ofx and y respectively. . a method called distanceFrom that accepts a Point2d object as the only argument, and returns the distance between this object and the Point2d object of the argument (N.B. the distance formula looks like: d I(x2-r). + (y2-y1)' where (x1.y) and (x2.y2) are the two points). a method called distanceFromOrigin that returns the distance between this object and the origin at a toString method that returns a String representation of this object of the form "(x.y)
