Object allocation is done dynamically with the new operator.

Memory is not infinite and can run out, which can cause new to fail.

Reclaiming free memory from unused objects is crucial in dynamic allocation schemes.

In some languages, memory release is manual.

Java uses garbage collection to automatically free up memory.

Garbage collection occurs in the background, without programmer intervention.

When an object has no more references, its memory is freed.

Recycled memory can be used for new allocations.

Garbage collection occurs sporadically during program execution.

Garbage collection is performed when there are objects to be recycled and there is a need to recycle them.

Garbage collection is time-consuming and only occurs when appropriate.

It is not possible to know exactly when garbage collection will occur.
