Explain what is meant by the syntax and the semantics of a programming language. Give Java examples to illustrate the difference between a syntax error and a semantics error. Use different examples than those found in the textbook.

Consider the UML below:

LoanInterest

 A bank charges varying interest rates for loans made by students depending on whether they are undergraduate or post-graduate students. Undergraduates are charged 12% on the loan amount and postgraduates 10%. Interest on a small-business loan is 15%.

a)   Write the Java code to declare the LoanInterest interface with the method interest().                                                                                                       

b)   Write the Java code for the definition of the Student class.                          

c)   Write the Java code for the definition of the subclass UnderGrad.              

d)   Construct objects of each of the subclasses and assign them to an arraylist.                                                                                                                               

1. What do you call the 1st array/index in two dimensional array?

2. What do you call the 2nd array/index in two dimensional array?

3. What is the output of the given code?

double[] sales = {12.5, 32.50, 16.90, 23, 45.68,

9, 10.5};

for(int i=0; i<sales.length; i++)

{ } System.out.print(sales.length);

4. What is the output of the given code?

double[][] sales = {

{12.5, 32.50}, (16.90, 23, 45.68}, {1, 2, 3, 4),

};

System.out.print(sales[2][1]);

5. What is the output of the given code?

double[][] sales = {

(12.5, 32.50), (16.90, 23, 45.68}, {1, 2, 3, 4),

}; System.out.print(sales[1][1]);

Instruction: Answer the following. Show all your solutions. For items 5 and 6: Given R b a f(x)dx = 4; R c a f(x)dx = 6; R b a g(x)dx = −2; and R c a g(x)dx = 1.

6. Suppose a < c < b, solve: i. ∫ b c [g(x) + 2f(x)]dx (3 pts.) ii. − ∫ a c g(x)dx (2 pts.)

1.    You must create a class named Bus.

2.    You should also create a main class named Main.

3.    In the Bus class, there should be member variables named:

   -(integers) = length, capacity, speed

   -(double) = fuel_capacity, fuel_burn_rate;

   -(String) = name, color;

4.    Create a constructor in the Bus class containing the parameters:

   -name

   -length

   -capacity

   -color

   -speed

   -fuel_capacity

   -fuel_burn_rate

5.Create the following methods in the Bus class:

     -*Must be a return method.

     -*Must have a variable named result. 

     -*Must compute the estimated travel hour/s of a bus using the member variables fuel

     -*Must compute the gas used within the given hour/s using the member variables

Create a short program that will print 123467.89 as currency using NumberFormat.

Sample Output:

I have ₱1,234,567.89 in my bank account.
