Solving your Java homework assignments can be difficult if you’ve never worked with a programming language before. If you’re teaching yourself how to code, you may find that learning the syntax and terms is easy but figuring out the theory behind programming isn’t. The best Java programming methods aren’t always explained in coding tutorials. Without making use of these best practices, you may find that your programs require more system resources to function than they should.
Here are seven of the best programming methods that will help you create efficient Java programs. If you’re still in need of help after reading this list, be sure to contact our team. We can help you with your Java coding and with implementing these best programming methods. Also, check out the best Java programming jokes to have a great laugh after long hours of studying.
Seven of the Best Java Programming Methods
While there are many great Java programming techniques out there, here are seven that you should practice in all of your coding.
- Always return an empty collection rather than null. If you send back a null element, you may have to have a number of if/else statements in other parts of your program to check to see if the collection is null. If you return an empty collection, that won’t be necessary.
- Be careful when you concatenate two strings using the plus sign if you’re doing so in a loop. This will create a new object each time the loop repeats, so you end up with many objects you don’t need. That wastes memory and can put additional strain on your computer’s processor.
- To take this one step farther, you always want to avoid creating any objects that aren’t necessary to your program. Doing so simply bogged down your memory.
- Java automatically manages memory, which does help prevent a lot of different memory leaks. However, there are a few Java programming methods you can use to further prevent this from occurring. First, always make sure you release any connections to a database once the query running on it is finished. Second, use Finally blocks whenever you can. Third, release any instances you have stored in Static Tables when finished with them.
- Allocate memory specifically for Java if your application is memory-intensive. If you don’t, you’re likely to see your computer greatly slow down when running your programs. You can allocate memory using the export command. The line of code begins with export JAVA_Opts= and then continues with four different variables that you enter. The minimum memory, maximum memory, the initial allocation, and the maximum amount of RAM that may be allocated at startup.
- When you’re trying to decide between using float and double, always use double. There’s actually very little difference in operation processing time between the two, and double is much more precise. There’s no reason not to use it.
- Another set of commands programmers may have to decide between is FileOutputStream and FileWriter. Both write data to files. The option you’ll want to use depends on what you’re outputting to the file. If it’s text, you should use FileWriter. If it’s raw bytes of data, use FileOutputStream.
