1) What do you understand by "String is Immutable"

Question

Accepted Answer

String is Immutable means it cannot be changed once created.

Immutable means unchangeable or cannot be modified.
In programming, when we say string is immutable, it means that once a string object is created, its value cannot be changed.
Any operation that appears to modify a string actually creates a new string object with the modified value.
For example, if we concatenate two strings, a new string object is created with the concatenated value.
This is different from mutable objects like lists, where we can modify the existing object without creating a new one.

Accepted Answer

String is immutable means that you cannot change the object itself, but you can change the reference to the object. When you execute a = "ty" , you are actually changing the reference of a to a new object created by the String literal "ty"
