All basic programming questions
The '==' operator compares object references, while 'equals(...)' compares the content of Java String objects.
Using '==' checks if two object references point to the same memory location.
'equals(...)' compares the actual content of the strings.
Example: String str1 = "Hello"; String str2 = new String("Hello"); str1 == str2 returns false, but str1.equals(str2) returns true.
String class is immutable in Java for performance and thread-safety.
Immutable objects are ideal for representing values of abstract data types
Optimization strategies like caching of hashcode, caching of objects, object pooling, etc can be easily applied to improve performance
String pooling would not be possible if Strings were mutable
Immutable objects are thread-safe by nature

Check if a number is prime and optimize the code.
Start by checking if the number is less than 2, in which case it is not prime.
Iterate from 2 to the square root of the number and check if any of them divide the number evenly.
If a divisor is found, the number is not prime. Otherwise, it is prime.
