In Java, objects are automatically destroyed when they are no longer referenced by the program and are eligible for garbage collection. You don't need to explicitly destroy objects in Java.
The process of garbage collection in Java is automatic. When an object is no longer being used by the program, the Java runtime system recognizes this and reclaims the memory used by the object. This is done by the garbage collector, which is a low-priority thread that runs in the background.
You can use the System.gc() method to suggest to the JVM that it perform garbage collection, but this is only a suggestion and the JVM is not required to actually perform garbage collection.
System.gc();
It's generally a good practice to let the JVM handle garbage collection automatically, rather than trying to manually destroy objects in your code.
