What security problems does Java help prevent?

• A. Phishing
• B. Cross-site scripting
• C. SQL injection
• D. Stack corruption and buffer overflow

Answer: (D)

Memory safety is at the heart of what Java helps prevent. The Java runtime enforces bounds checking and safe memory access, and you don’t have direct pointer manipulation or manual memory management. Arrays and strings are checked for every access, so writing past the end of a buffer or trying to overwrite return addresses on the call stack isn’t possible in the same way it is in languages that give you unchecked memory access. This design limits stack corruption and buffer overflow vulnerabilities by construction, making them far less likely in typical Java applications. Phishing and cross-site scripting are more about how users interact with apps and how input is handled in web interfaces. Java by itself doesn’t automatically shield you from those threats; they’re mitigated through secure web practices, input validation, and proper encoding. SQL injection is a data-layer worry best addressed by using safe query practices (like prepared statements) and proper parameter handling, which are programming patterns you can use in any language, not a feature unique to Java. The language’s emphasis on memory safety is what makes stack and buffer-related bugs unlikely, which is why that option is the best answer.
