12/10/2023 0 Comments Heap vs stack java![]() Assume that test1's memory address was 0x33d444 and that test2's address was 0x99f775. What you're actually doing when you write this is assigning the addressof the test1 object to the test2 object. Say you've got two Test objects, and you assign the first tothe second, like this: Test test1 = new Test() Test test2 = new Test() test2 = test1 An object reference on the stack isonly an address that refers to the place in heap memory where that object iskept. Stack memory stores primitive types and the addresses of objects.The object values are stored in heap memory. These are called stack memory andheap memory. There are two kinds of memory used in Java. Thisreference represents the location where the object and its metadata are stored. Anobject reference variable must then hold a reference to those values. The associationbetween each value and the object must be maintained throughout its life. They oftenhold multiple values, each of which must be stored in memory. ![]() Objects must be stored differently because they are more complex. The appropriate amount of space is allocated given the data type, and thevariable is stored in memory just as it is. Primitive data types have just one value to store. In this section we will look at how variables are stored in memory in Java.We are examining memory in Java at this point so that you can understand at alower level what happens when you create and manipulate the objects that make upyour programs.
