The 6 Java Best Practices Everyone Should Apply

In today’s fast-pace world, where many programming languages that formerly had a big presence in the market are now gone. Java remains relevant and is developing with the trends. According to Oracle data, as of December 2019. Java was the number one programming language for contemporary applications such as DevOps, AI, VR, Big Data, Mobile, and microservices development. As a result, fresh developers are generally more eager to learn Java. This evergreen programming language appears to be the greatest place to begin. Working with the Java coding best practices can significantly enhance the quality of the code. Making it more understood to other people, more adaptable, reusable, and manageable.

6 Java Best Practices To Follow

Let’s discuss the 6 best Java practices you should remember while programming.

Never leave a catch block empty

Skilled coders usually write a distinct, relevant note in the catch block when dealing with errors. Newer programmers frequently leave the catch block empty as they are the only ones working on the code at the beginning. However, when the program catches an exception, and the catch block is empty, the program does not show any information, which can make debugging more difficult and time-consuming. 

Avoid Redundant Initializations

It may seem that having an error-free program is all one needs, but this is not true. A code creates in accordance with established rules and programming standards. Applying the best practices of Java coding can immensely enhance the quality of the code by making it more comprehensible for you and other people, flexible, reusable, and maintainable. Some Java best practices can also boost the code’s efficiency. To begin, a proper naming convention chose for the Java project prior to writing any code. Random names should not assign merely to please the compiler; instead, meaningful and unambiguous labels should be used.

Use of single quotes and double quotes

Everyone knows that double quotation marks symbolize strings while single quotes intend for characters. Yet, in a few uncommon cases, it can go astray. When it is essential to connect characters to formulate a string, it recommends using double quotation marks for the characters that link. If double quotation marks are employed, the characters will be regarded as ordinary strings without problems. However, if single quotation marks are utilized, the numerical values of the characters will be taken into account due to a procedure known as widening primitive conversion.

Avoiding Memory leaks

Everyone knows that double quotation marks symbolize strings while single quotes intend for characters. Yet, in a few uncommon cases, it can go astray when connecting characters to formulate a string is essential. It recommends using double quotation marks for the characters that are about links. This is because if double quotation marks that employed, the character regards as ordinary strings and there will be no problems. However, if a single quotation mark utilizes, the numerical values of the characters take into account due to a procedure known as widening primitive conversion.

Efficient use of Strings

In Java, manipulating Strings is relatively simple but manages prudently to protect against excessive memory access. For example, when two Strings connect inside of a loop, a different String object creates for each cycle. If the number of loops is large, it can cause much memory waste and slow down the performance. Another case would be the initiation of a String Object – a Java best practice is not to use constructors for initiation and to complete the process directly. This is fast compared to using a constructor.

Conclusion

Java makes it easy to manipulate strings, but one must be careful to avoid overusing memory. For example, when appending strings in a loop. A new object creates at each iteration, which can be extremely memory-consuming and slow down performance if the loop executes a lot of times. To optimize speed, the best approach is to instantiate strings without using a constructor as this is faster than employing the constructor method.
