Low latency  2. High Throughput  3. Efficient resources usage (CPU and memory) Typical stages involved in the GC are, 1. Mark (Tracing) - the objects are tree represented and from the application root reachable nodes are painted (LIVE) and unreachable (NON-LIVE) are marked for GC. 2. Sweep - Nonlive objects cleared from the heap memory  3. C

A DTO can be a JavaBeans (encapsulated) or POJO (no constructor) or an immutable Record class (added advantage on serialization), that maps the data from the database layer domain model to the presentation layer, restricting the data on a need-to-know basis and acts as a proxy providing filtering and preprocessing. https://snyk.io/blog/how-to-use-java-dtos/ By employing static code analysis tools, the NullPointerException feasibility on the code flow is determined, making the code not only null-safe but also cutting down the exception propagated stacktrace given in the piped code sequence invocation
