immutable class in java is thread safe

Immutable objects are often useful because they are inherently thread-safe. Basic thread safety with any shared object is accomplished by ensuring that whatever allows threads to access the object does not take place until the constructor returns.

Benefits Of Immutable Class In Java Java Developer Central

In other words.

. Immutable objects are inherently thread-safe. This is something to keep in mind when trying to achieve thread safety through immutability. Immutable objects are inherently thread-safe.

To summarize I would say. If we need to share state between different threads we can create thread-safe classes by making them immutable. In Java all the wrapper classes like Integer Boolean Byte Short and String class is immutable.

This implementation is NOT thread safe. The mutable class examples are StringBuffer JavautilDate StringBuilder etc. Where do we use immutable class in Java.

The code of as it is written is not inherently thread-safe. If several threads call hashcode at the same time the returned value could be different for each thread. Since there is no way the state of an immutable object can change.

Prior to going ahead do go. Immutability is a powerful language-agnostic concept. However the way you copy the lists prevents concurrent modifications.

Immutable objects are often useful because they are inherently thread-safe. Immutable classes make concurrent programming easier. They do not require synchronization.

The ImmutableValue class is thread safe but the use of it is not. We can create our own immutable class as well. The Mutable objects are may or may not be thread-safe but the immutable objects are thread-safe by default.

The question is is this class. Whereas immutable object have just one state which is first and foremost benefit of Immutable Class. Immutable classes make sure that values are not changed in the middle.
