transient vs volatile modifier in Java
What is difference between transient and volatile variable or modifier in Java is one of the most common Serialization Interview Question in Java. Though volatile variables are not related to Serialization at all, this question is mostly asked in conjunction with other Serialization question. Both transient and volatile modifiers are completely different to each other. In fact this question is as popular as Serializable vs Externalizable in Java. Main difference between transient vs volatile variable is that transient variables are not serialized during Serialization process in Java while volatile variables are used to provide alternative synchronization in Java. By using volatile keyword or modifier on fields, signals compiler that this variable is accessed by multiple thread and any reordering or optimization by compiler should be avoided. In this Java article we will see some difference between transient and volatile variable by learning each of them and When to use transient and volatile variable in Java.
