QUESTION
I'm trying to make Java programs work on Visual Studio Code. I've downloaded the Microsoft extension, downloaded the JKE from Oracle, and now I'm trying to run the proverbial "Hello World" Java program to make sure it works. Here is my program (I got it from the "Get Started" tutorial so it should be fine):
...ANSWER
Answered 2020-Dec-07 at 17:34The answer to this problem is to double check, nay, triple check your file names. The problem is that with Visual Studio Code's way of running programs (that is hitting the run button), any '
can cause serious problems. This is due to the fact that VS Code uses '
to quote file paths. Thanks to Eliott Frisch for pointing this out to me.
There are two possible solutions to this:
Change your folder name to remove the problematic character. In my case, however, my folder was running programs so I couldn't do that. This leads me to...
Create a new folder and move your programs there. This is, in my opinion, the best solution since you generally want a separate folder for your programs anyway.
Note that this is especially important for Java programs, since in Visual Studio Code you can't run Java programs with java name.java
. Similarly, this is not important for Python programs, since those can be run with python name.py
and therefore don't require any file names.
QUESTION
I'm an APCSA student and am trying to answer a question in the textbook. Basically, given an ArrayList of different words, I need to create and return an ArrayList of type ArrayList with 26 "buckets", each containing all the words that start with "a", then "b", and so on, until the intial ArrayList is completely sorted by the first letter of the words. The method can only parse the initial ArrayList once and cannot alter it. As my code stands now, I keep getting an out of bounds error. If someone can point me in the right direction, that'd be awesome, thanks. This is what I have currently, and I have no idea if it's even close to right:
...ANSWER
Answered 2020-Feb-10 at 02:01The '26' there just says that the arraylist is optimized to handle 26 elements. It is still an empty arraylist with zero elements in it. At the top of your for (26) loop, try adding buckets.add(new ArrayList<>());
.
Also, you're not doing what the question asks; you're looping the input 26 times, the question as asked wants you to loop that only once. (and as it is homework, it wouldn't help your education if I just caught this fish for you).

Install APCSA
You can use APCSA like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the APCSA component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
