Which one of the following has a very large responsibility for managing memory in Java?
1) Garbage Collector
2) Malloc Statements
3) Constructors

5) JKernel
Looking forward for an early reply.

As to 1-3
Responsible for allocating memory upon object construction and freeing memory once objects are no longer referenced.
Java doesn't have explicit memory functions like malloc. Even at a lower level the JVM itself doesn't call a c malloc statement, but there is a mechanism where it asks the OS for a reserved chunk o' memory.
Constructors play a role in allocating memory at a higher conceptual level in that child objects are often initialized there, but I don't think it's what the question is looking for.
Here's a great whitepaper describing Java's Memory Management.
