Memory allocations for arrays in Java

In Java, arrays are also reference types, so they are allocated in the heap.

For example:

int New int [5];  for (int i=0;i<a.length;i++) {    int[i] = i;}

The memory allocation diagram is as follows:

Above is an array of primitive types, following the memory allocation of the reference type array. Look at the definition of the reference type first:

classT { Public intID;  PublicString name;  Public intAge ;} Public classTest { Public Static voidMain (string[] args) {t[] T=NewT[3]; t[0] =NewT (1, "Zhang San", 28); t[1] =NewT (2, "John Doe", 21); t[2] =NewT (3, "Harry", 45); }}        

Memory allocations such as:

You can see that in an array of reference types, the actual reference to each object is stored.
