We are on to more objects and writing the classes for them. I think we are getting closer to my goal of making buttons that can be turned on and off and other cool things like that. I hope everything isn't to to difficult because I don't want to not be able to do something that I want. So far I've been doing just fine so I'm not too scared. I'm eager to have lecture tomorrow so I can get a better understanding of classes of objects and such. I hope I don't forget how to do everything I learned when spring break is over!

The lesson for tomorrow seems to be pretty simple. It is just making matrices. It MatLab we pretty much only did matrices since it is matrix laboratory. The only thing I am confused about is syntax which I'm sure will be explained much nicer tomorrow at lecture. I have the understanding of what object is made but confused on how to make it. I'm guessing it won't be super difficult. It will probably be the same as arrays or other objects. I feel that we will be able to do a lot more applications with multidimensional arrays compared to using just one dimension arrays.

Homework to program is finished! After I figured out out to get a correct difference it sort of just flowed out of me. Tested it will all my tests. It broke once and I got it fixed so hopefully it is going to pass a lot of tests that other students have. I was very surprised that it only took me as long as it did. That makes me feel more confident in my programming. I eager to see what other objects we will be making in the next few weeks. Each one we learn seems to make programming specific tasks a ton easier so I'm hoping for some cool objects.

Brainstorming has begun for homework number two. I had planned to start it this weekend on a car trip but forgot I didn't have Eclipse on my netbook. So I will be doing it this week hoping for the best. I'm glad the arrays are fresh in my mind for this. I think I'll be able to do a decent enough job on this assignment. I'm glad that I only have one exam this week plus all weekend to figure this out. I think that writing out the tests has made me more aware of what I need to put into the program to get out the right answer. I guess we will wait and see. Best of luck to everyone!

Array lists are much much better than regular arrays. I like to be lazy. There is just so much you can do very quickly with the array lists. I like that they move over when you insert values in the middle. I'm excited to see what other kinds of objects we do this semester. I think it would be cool to make like a calculator or something using Java. Where it would show up as an object that you can click the buttons and then the program would do the math. I think that would be really fun to do. I would be very proud of myself if I could make that.

Tomorrows homework has me a bit confused. I think once I see how it works I'll pick it up but until then I'm not fully grasping it. I did good on my lab quiz. I thought overall it went well. It was a good mix of the things we have learned. Some stumped me for a bit but just trying and trying I got them to work. I think the main thing you need with programming is patience. This is something I lack sometimes. I found if I do some stuff for a while and am not getting it I can go away from it and come back and fix it easier that I would have been able to.

Array/Methods

The arrays don't seem to terrible. MatLab is all about matrices so we really got those worked into our brains. I like arrays for the fact of making life easier. Who would want to write a bunch of the same code to do the same thing a lot of times. With arrays all you do it just type in the values you want. I'm sure there is going to be some difficult things with arrays just like everything but for the basic idea of them they don't seem to hard. Methods turned out to be not to difficult at all which was nice. With the lectures I feel like I have a good understanding of them.

First Homework

So I almost have my homework getting the right answer. I decided I'd write out the code first and it seemed to work well. I just typed stuff that I had written down and it all came together nicely. I didn't think my peak and valley would work but my slope would. It turned out to be the opposite my slope isn't getting the right values but my peaks and valleys are. I think just sitting down and thinking about it a little more I will be able to get it. I just need to start over on my thinking. Hopefully I can figure it out tonight and then I can submit it tomorrow!
