In this tutorial, we’ll further explore why the Java language designers decided to keepStringimmutable. 2. What Is an Immutable Object? An immutable object is anobject whose internal state remains constant after it has been entirely created. This means that once the object has been assigned to...
The immutable and final nature of String class is intentional. This is by design to offer several features and advantages. In this guide, we will discuss these advantages with examples. Reasons for String Immutability Security: Sensitive Data: Immutabili

immutable, signifying that the content of a String object cannot be modified once it has been instantiated. However, it is important to note that while the String object itself cannot be changed, the reference variable pointing to the String object can be reassigned to a different String object...
Spark Scala RDDs are immutable, which means that once an RDD is created, it cannot be changed. This is by design and is a key characteristic of RDDs in Spark. There are a few reasons why RDDs are immutable: Simplicity: By being immutable, RDDs are simple and easy to reason about. ...
