I have my code here and I am getting errors (I have also attached my code): " import java.util.Compiler; public class Test Score { public static void main(String[] args) { Scanner scan = new Scanner(System.in); System.out.println("Ënter the first exam Score: "); Double Score1 = scan.nextDouble(); System.out.println("Enter the second exam Score: "); Double Score2 = scan.nextDouble(); System.out.println("Enter the third exam Score: "); Double Score3 = scan.nextDouble(); System.out.println("Enter the fourth exam Score: "); Double Score4 = scan.nextDouble(); System.out.println("Enter the fifth exam Score: "); Double Score5 = scan.nextDouble(); Double total = Score1 + Score2 + Score3 + Score4 + Score5 Double average = total/5; if (average >= 90) { System.out.printf("your average was a: %f and recieved an A in this Class", average ); } else if (average >= 80) {...

JAVA CODE: check output

there are 2 errors in this code can you fix it for me? public class Exercise09_10 { public static void main(String[] args) { Scanner input = new Scanner(System.in); System.out.print("Enter a, b, c: "); double a = input.nextDouble(); double b = input.nextDouble(); double c = input.nextDouble(); QuadraticEquation equation = new QuadraticEquation(a, b, c); double discriminant = equation.getDiscriminant(); if (discriminant < 0) { System.out.println("The equation has no roots"); } else if (discriminant == 0) { System.out.println("The root is " + equation.getRoot1()); } else // (discriminant >= 0) { System.out.println("The roots are " + equation.getRoot1() + " and " + equation.getRoot2()); } } }

8) Now use the Rectangle class to complete the following tasks: - Create another object of the Rectangle class named box2 with a width of 100 and height of 50. Note that we are not specifying the x and y position for this Rectangle object. Hint: look at the different constructors) Display the properties of box2 (same as step 7 above). - Call the proper method to move box1 to a new location with x of 20, and y of 20. Call the proper method to change box2's dimension to have a width of 50 and a height of 30. Display the properties of box1 and box2. - Call the proper method to find the smallest intersection of box1 and box2 and store it in reference variable box3. - Calculate and display the area of box3. Hint: call proper methods to get the values of width and height of box3 before calculating the area. Display the properties of box3. 9) Sample output of the program is as follow: Output - 1213 Module2 (run) x run: box1: java.awt. Rectangle [x=10, y=10,width=40,height=30] box2: java.awt....
