- What is a primary advantage of using Java Streams over traditional loops?Ensures synchronous execution · Automatically retries failed operations · Stores data in-memory efficiently · Allows declarative, parallel processing
- Identify the correct method signature from this Runnable implementation snippet: class MyTask implements Runnable { @Override public ??? { System.out.println("Task running"); } }void process() · void executeTasks() · void run() · void initiate()
- Which statement about the Java Memory Model (JMM) is accurate?Optimizes thread instantiation rates · Manages memory visibility between threads · Regulates virtual memory addresses only · Handles physical memory allocation
- Which lambda expression parameter syntax is invalid in Java?(a, b) -> a - b · a -> { return a; } · a, b -> a + b · (x) -> x * x
- What task is specifically handled by the Java Virtual Machine (JVM)?Compiles high-level code · Converts bytecode to native code · Manages memory directly · Executes source code directly
