Can we declare array dynamically?
Dynamic arrays in C++ are declared using the new keyword. We use square brackets to specify the number of items to be stored in the dynamic array. Once done with the array, we can free up the memory using the delete operator. Use the delete operator with [] to free the memory of all array elements.

Is array dynamic or static in Java?
Difference Between Static Array and Dynamic Array
Static Array | Dynamic Array |
---|---|
The size of static array is fixed. | The size of dynamic array is fixed. |
It is located in stack memory space. | It is located in heap memory space. |

Can ArrayList size change during run time in Java?
It can change its size during run time. In Java, ArrayList is a resizable implementation. It implements the List interface and provides all methods related to the list operations. The strength of the dynamic array is: In the dynamic array, the elements are stored contiguously from the starting of the array and the remaining space remains unused.
Why is array2 in Java static?
If there were no assignment after the initial assignment, array2 would still be static in the sense that it can’t be changed (because there is no code to do so), although by declaration changing it is allowed. A concrete instance of an array can not be resized ever once created (there is no language element to express resizing an array in java).
