SoftReference Nesnesi

Giriş

Açıklaması şöyle. Yani WeakReference'tan biraz daha katıdır ve OutOfMemory oluncaya kadar belleği bırakmamaya çalışırlar

Soft References behave very similarly to the weak ones with the difference that they are not that eager to let the object to be collected. They behave like strong references until the memory runs out. If the JVM starts reaching its upper ram limits it will collect the soft referenced objects, so in theory they should never cause an OutOfMemory error. 

Örnek

Şöyle yaparız

List<SoftReference<Object>> lst = new ArrayList<>();
 while (true) {
  lst.add(new SoftReference<>(Files.readAllBytes(Paths.get("huge.txt"))));
 }
