How Garbage Collection works in Java? Explained

I have read many articles on Garbage Collection in Java, some of them are too complex to understand and some of them don’t contain enough information required to understand garbage collection in Java.

Garbage collection works by employing several GC algorithms like Mark and Sweep, G1, etc. There are different kinds of garbage collectors available in Java to collect different areas of heap memory like you have serial, parallel, and concurrent garbage collectors in Java.

Why String is Immutable or Final in Java? Explained

The string is Immutable in Java because String objects are cached in the String pool. Since cached String literals are shared between multiple clients there is always a risk, where one client's action would affect all other clients. For example, if one client changes the value of the String "Test" to "TEST", all other clients will also see that value as explained in the first example. Since caching of String objects was important for performance reasons this risk was avoided by making the String class Immutable. At the same time, String was made final so that no one can compromise invariant of String class like Immutability, Caching, hashcode calculation, etc by extending and overriding behaviors. Another reason why the String class is immutable could die due to HashMap.
