So, it is better to set the reference to null, explicitly. Because they live for the entire life of the application, by default. Time out the session when no longer used.Do not store a massive amount of data in the session.While writing code, remember the following points that prevent the memory leak in Java.

Bugs in the Third-party Libraries: Bugs in AWT and Java Swing packages are another cause of memory leak.

JNI APIs are used to embed native libraries in the Java code.

Failure to Clean-up Native System Resources: Native system resources allocated by a function external to Java.

Because they live in the memory till the application's life span.

Using Long-live Static Objects: Using static objects also leads to a memory leak.

The garbage collector is failed to reclaim the memory because another object still refers to that unwanted object.

Using Unwanted Object Reference: These are the object references that are no longer needed.

There are the following causes of memory leaks in Java:

The usage of memory increases during the life span of an application.

The performance of the application consistently decreases.

If any Java application suffers from a memory leak, you notify the following things: There are the two parameters (options) for setting up the heap size: Note: We can specify the initial and maximum heap size for the application. The following figure represents the memory leak.

It also affects the reliability of the application. Because the unused objects still being referenced that may lead to OutOfMemoryError. In Java, the memory leak is a situation when the garbage collector does not recognize the unused objects and they remain in the memory indefinitely that reduces the amount of memory allocated to the application. In this section, we will understand what is a memory leak in Java, its causes, detect and fixing of memory leaks.

Nevertheless, there is a chance of memory leak in a Java application. Therefore, the programmer need not to manage memory manually like other procedural programming languages (C, and C++).

If the object is no longer is used by the application, the garbage collector automatically removes that object and free up space for other applications. When we create an object using the new keyword, the JVM automatically allocates memory for that object. Java provides out-of-box memory management.
