Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • ✗

    Use of pointers for direct memory access

    Why it's wrong here

    Java does not have pointers; it uses references and handles memory safely.

  • ✗

    Support for multiple inheritance of classes

    Why it's wrong here

    Java supports single inheritance for classes; multiple inheritance is achieved through interfaces.

  • ✓

    Platform independence through bytecode and JVM

    Why this is correct

    Java source code is compiled to bytecode, which runs on any JVM.

  • ✓

    Automatic memory management (garbage collection)

    Why this is correct

    Java automatically manages memory, freeing objects no longer in use.

  • ✓

    Strong type checking at compile time

    Why this is correct

    Java enforces strong typing, catching type errors during compilation.
