In Java, arrays are created on the heap memory.
The heap memory is a part of the memory that is allocated to a running Java program. It is used to store objects and data structures that are created during runtime, including arrays. When an array is created in Java, a block of memory is allocated on the heap to hold the elements of the array.
The size of the array and the data type of its elements determine the amount of memory that is required. Once the memory is allocated, the array can be accessed using its reference variable, which is created on the stack.
It's worth noting that the stack and heap are two different regions of memory used by Java. The stack is used to store primitive data types, method calls, and references to objects on the heap. The heap is used to store objects and data structures, including arrays.
