Why strings are immutable in Java?
String is immutable for several reasons, here is a summary: Security: parameters are typically represented as String in network connections, database connection urls, usernames/passwords etc. If it were mutable, these parameters could be easily changed. Synchronization and concurrency: making String immutable automatically makes them thread safe thereby solving the synchronization issues. Caching: when compiler optimizes your String objects, it sees that if two objects have same value (a="test", and b="test") and thus you need only one string object (for both a and b, these two will point to the same object). Class loading: String is used as arguments for class loading. If mutable, it could result in wrong class being loaded (because mutable objects change their state).
Good answer, Stacy. An additional advantage might be this: immutable strings are better suited as hash map keys.
what are parameters
Decimal to Hex in C++
What i do wrong ?
Please rearrange int array:
Tuple Hadouken : I cannot tell what this is, in Python 3.11 (problem likely not due to it being in 3.11 though)
