Objects, mainly.
if a variable is of value type memory is allocated on stack memory.. if it is of reference type,memory is allocated on heap memory..
To give java more memory there are a series of steps to follow. To start, go to the computer's control panel, select programs, then go to java settings. This should initiate the Java control panel to pop up. Click on the Java tab followed by the view button. Click on the "runtime parameters" and input the specifics desired. Once finished hit okay then apply and it should increase the memory on your Java.
A running java program only has access to the memory allocated to it by the Java Runtime Environment. Java by design does not allow access to absolute memory locations which is required to scan for memory resident viruses. A Java-based anti-virus program can still read a virus-signature file and use it to scan for those patterns in files to identify possible infected files.
The new keyword in programming languages like C++ and Java allocates memory on the heap for an object or data structure. When new is called, it requests a block of memory sufficient to hold the specified type, initializes that memory (if applicable), and returns a pointer or reference to the newly allocated memory. This memory remains allocated until it is explicitly deallocated using delete in C++ or is automatically reclaimed by the garbage collector in languages like Java. Proper memory management is crucial to avoid memory leaks and ensure efficient use of resources.
Java has a fairly sophisticated garbage collection system, and in general you don't worry about memory leaks, as they only happen in a few very specific circumstances (notably, when adding listeners to Swing GUI objects and not removing them). If you need more sophistcated memory management, java provides the clases in the java.lang.ref package.

In Java, a heap is a data structure used to store and manage objects dynamically allocated during program execution. It is a region of memory where objects are stored and accessed by the Java Virtual Machine (JVM). The heap is responsible for memory allocation and deallocation, allowing objects to be created and destroyed as needed. This helps manage memory efficiently and ensures that the program runs smoothly without running out of memory.
Contiguous memory address are allocated to an array or vector.

use free() how does the system know what range of memory it has allocated use free() how does the system know what range of memory it has allocated
Memory page.
Main Memory (RAM).
The maximum memory that can be dynamically allocated depends on the size of the heap memory. Dynamic blocks of memory can be allocated in system heap until it is not full.
Memory is allocated by malloc from the heap.... so max mem = size of heap that is free...
