Thread: Completely new to Java, don't understand my first Assignment

So I am college student and I am completely new to Java, and I am having a really rough start. Unfortunately, this is more of an intermediate class, and I cannot take a fundalmentals course because it doesn't fit into my Education plan. I've read the chapters and I have my first Assignment, but I don't even understand how this works. Can some explain to me what I am suppose to do? I have talked to my professor a million times and he keeps telling me to drop out and take an easier course, but I do not have that option.

This is the assignment:

Edit the code in both the Car.java file and Main.java file wherever you see a TODO such that all the tests pass (Expected value = Actual value) when you run the application.


public void decelerate(Integer amountToDecreaseBy) {
// TODO YOUR CODE GOES HERE


Car myBMW = new Car();
// TODO YOUR CODE GOES HERE

I don't really know what I am exactly suppose to edit here... and I am suppose to make it work somehow. I just feel like this wasn't explained all that well or that I am just so bad at Java, that I do not understand the assignment. Help please!

We cant do anything with that either. Its far too little information to actually help you.

By the way, you wont find anybody here who will write the code for you. If you try it, we can try to help you by giving you hints and tips, but thats about it.
If you want to actually learn how to program, try online tutorials or a book, or perhaps both.

I don't want anyone to write anything for me, I just don't understand what exaxtly I am suppose to do

As I said, we dont know either.
After all, you didnt post the tests that need to pass. The TODO by itself is quite pointless unless you have a look at the tests.

Lucky you had a java course to begin with. :\

Your main file main method is where the file starts. I don't know how you are supposed to display the output, if it's to the console or whether you are supposed to make a loop yourself or if the main method has it ready to go but....

in your main method, you would put...

int increment = (actualvalue-expectedvalue)/4;
 
while(myBMW.speed > expectedvalue){
myBMW.decelerate(increment);
//or you can just put in the different between the car's speed, and what you want the value to equal
//instead of my "increment" variable which would require this to loop 4 times. :)
}
 
System.out.println(myBMW.speed);

You should know where to fill in any errors, or adjust according to your project. If you don't, look online for thenewboston java tutorials on youtube. If you are still lost, then I can't help you any further via forum.
