why is string is immutable in java?
  • In Java, string objects are immutable in nature which simply means once the String object is created its state cannot be modified.
  • Whenever you try to update the value of that object instead of updating the values of that particular object, Java creates a new string object.
  • Java String objects are immutable as String objects are generally cached in the String pool.
  • Since String literals are usually shared between multiple clients, action from one client might affect the rest.
  • It enhances security, caching, synchronization, and performance of the application.
