1Z0-811 What is Java Practice Question
Which THREE are benefits of Java's platform independence? (Choose three.)
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Ability to run on any device with a JVM
Options A, B, and E are correct. Java's platform independence allows code to run on any device with a JVM (A), enables the 'write once, run anywhere' principle (B), and enhances security through sandboxing, which isolates untrusted code (E). Option C is incorrect because faster execution compared to native code is not a benefit; Java often runs slower due to interpretation or JIT compilation. Option D is incorrect because automatic memory management (garbage collection) is a feature of the JVM but not directly a benefit of platform independence; it is a separate advantage of Java.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Ability to run on any device with a JVM
Why this is correct
Platform independence allows the same bytecode to run on any device that has a JVM implementation.
- ✓
Write once, run anywhere
Why this is correct
"Write once, run anywhere" perfectly articulates the primary benefit of Java's platform independence. This capability arises because Java source code is compiled into platform-agnostic bytecode, rather than machine-specific native code. This bytecode can then be executed by any Java Virtual Machine (JVM), which is itself tailored to the specific underlying operating system and hardware architecture. Consequently, developers can write an application once and deploy it across diverse computing environments without modification or recompilation, directly satisfying the requirement for platform independence.
- ✗
Faster execution compared to native code
Why it's wrong here
Java is typically slower than compiled native code due to the abstraction layer.
- ✗
Automatic memory management
Why it's wrong here
Garbage collection is a separate advantage, not directly from platform independence.
- ✓
Enhanced security through sandboxing
Why this is correct
The JVM provides a sandbox to execute untrusted code safely.
