Scenario: Your application is running out of memory due to excessive use of Long objects. How can you optimize memory usage?

Expected Answer:

• Use primitive long instead of Long where possible to reduce memory overhead.
• Use Long.valueOf() instead of new Long() to leverage the Long cache for values between -128 and 127.

Example:

long primitiveLong = 100L; // Memory efficient
Long cachedLong = Long.valueOf(100L); // Uses cached values
