Memory allocation in Java

 The Java Memory Allocation is divided into following sections :

• Heap – stores objects and arrays. It is shared by all threads. The Garbage Collector cleans up objects that are no longer needed.
• Stack  – stores method calls, local variables and references. Each thread has its own stack.
• Code  – contains the instructions that the JVM executes.
• Static – contains class-level data, such as static variables, which belong to the class rather than to a specific object.
