Garbage collection

• 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 no longer has references, its memory is freed.

• Recycled memory can be used for new allocations.

• Garbage collection occurs sporadically during program execution.

• Garbage collection is carried out when there are objects to be recycled and the 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.
