The phrase "write once, run anywhere" dates back to 1995 and aptly captures the power of Java. This is a programming language that is reliable, secure, and quick. In recognition of this, Java is widely used for coding. 
However, as with any programming language, it is important to join in java developer course in pune and get familiar with it. But before you consider learning any language, it's important to become familiar with key information that helps to run the code efficiently.

Avoid Writing Long Methods

The methods need to be concise and suited to a single task, with no more than one functionality. The method is loaded in stack memory during method call and class loading, so concise methods make maintenance easier and performance better. 
Procedures that need high processing power and size will use memory and CPU cycles during execution. Try to divide the approaches into smaller ones at appropriate, rational intervals. Also, if you want to improve your Java skills, enrol on a java developer course in pune to learn basic concepts, data types, operators, functions, and more.

Avoid Creating Unnecessary Objects

The creation of Java objects might slow down your code and consume a lot of memory. Reusing existing materials is preferable to creating new ones wherever possible. Maintaining a pool of reusable objects that can be borrowed and returned as needed is one way to achieve this with object pooling.
If you would prefer not to build new objects every time, you may also use the flyweight pattern as an alternative to share a group of objects. This will significantly improve the performance of your Java code. Join a java course in pune to learn the nuances of it. 

Avoid Multiple If-else Statements

In Java programming, you use conditional statements for decision-making. It is not advisable to use conditional statements unnecessarily. Performance will be impacted if you use too many conditional if-else statements, as the JVM will have to compare the circumstances. If looping statements like for, while, etc. are used with the same, this could get worse. 
Try grouping the conditions in your business logic to get a boolean outcome that you can then use in the if expression when there are too many conditions. A switch statement you might have learned in java classes in pune can also be considered in place of multiple if-else statements when that is feasible.

Use Static Procedures and Variables

The efficiency of your Java code can be significantly improved by using static variables and methods. Static variables and methods do not need to be instantiated each time they are used, which helps to save time and memory use because they are part of a class rather than an instance of the class. 
However, as this can make your code less modular and more difficult to maintain, it is important that you use them selectively and avoid overusing them. By enrolling in a java full stack developer course in pune, you can learn using the right static procedures and variables.

Use Stored Procedures Rather Than Queries

Creating stored procedures and invoking them during processing is preferable to writing intricate and lengthy queries. Precompiled stored procedures are stored in the database as objects. 
While a query with the same business logic is executed every time it runs through the application, the stored procedure takes less time to execute than a query with the same logic. Also, as you are not sending the complex query to the database server for execution each time, the stored procedure offers an advantage in terms of data transfer and network traffic.

As Far as Possible, Use Primitive Data Types

Eight primitive types are available in Java, which you will learn during online full stack training in pune. This includes boolean, byte, short, int, long, float, double, and char. These are the fundamental units from which complex types, defined by programmers, are composed. The JVM can store the value on the stack rather than the heap by choosing primitive types that are suitably different from their wrapper classes. 

Use Profilers to Identify Bottlenecks
Using profilers is another key aspect of Java optimization you would be learning during java courses in pune. Every programmer eventually finds that the written code needs to be speed up if it is not completely efficient. To identify the weak points in the ensuing lines of code, it is essential to use a profiler. That way, you can improve Java applications' performance by knowing which regions want development.
