What features make Java robust?

• A. Operator overloading and multiple inheritance
• B. Low-level pointer arithmetic
• C. Garbage collection, exception handling, and memory allocation
• D. Dynamic typing

Answer: (C)

Robustness in Java comes from how the language manages memory and errors in a safe, predictable way. Garbage collection automatically reclaims objects that are no longer in use, which helps prevent memory leaks and crashes caused by dangling references. Exception handling gives a structured path to deal with unexpected problems, allowing programs to recover or fail gracefully rather than crash in an uncontrolled way. A managed memory model with safe allocation means the runtime enforces checks like array bounds and type safety, reducing vulnerabilities from low-level memory corruption. These aspects work together to make Java programs more reliable and resilient across different scenarios. By contrast, operator overloading and multiple inheritance can add complexity, low-level pointer arithmetic invites unsafe memory access, and dynamic typing would reduce type safety—none of which align with Java’s design for robustness.
