How do you use transient?

transient is a variables modifier used in serialization. At the time of serialization, if we don't want to save value of a particular variable in a file, then we use transient keyword. When JVM comes across transient keyword, it ignores original value of the variable and save default value of that variable data type.

Why are transient variables not serialized?

In case you define any data member as transient, it will not be serialized. This is because every field marked as transient will not be serialized. You can use this transient keyword to indicate the Java virtual machine (JVM) that the transient variable is not part of the persistent state of an object.

Can transient variable be serialized?

Serialization is the process of converting an object into a byte stream, and deserialization is the opposite of it. When we mark any variable as transient, then that variable is not serialized. Therefore, the serialization process ignores the original value of the variables and saves default values for that data type.

What does transient mean in Java?

transient is a Java keyword which marks a member variable not to be serialized when it is persisted to streams of bytes. When an object is transferred through the network, the object needs to be 'serialized'.

What is transient value?

A transient variable is a variable that can not be serialized. According to Java Language Specification [jls-8.3. 1.3] – “Variables may be marked transient to indicate that they are not part of the persistent state of an object.”

What does transient mean?

transient, transitory, ephemeral, momentary, fugitive, fleeting, evanescent mean lasting or staying only a short time. transient applies to what is actually short in its duration or stay.

What is the use of transient?

The transient keyword in Java is used to avoid serialization. If any object of a data structure is defined as a transient , then it will not be serialized. Serialization is the ​process of converting an object into a byte stream.

What is difference between transient and static in serialization?

Transient variable will be ignored during serialization. ... Static variable will be serialized if the value is initialized during declaration itself. If a variable contains both transient and static keyword, also if the value is initialized during declaration, then it will be serialized.

Why the string is immutable?

The string is Immutable in Java because String objects are cached in the String pool. ... Mutable String would produce two different hashcodes at the time of insertion and retrieval if contents of String was modified after insertion, potentially losing the value object in the map.

What is transient in hibernate?

Hibernate defines and supports the following object states: Transient - an object is transient if it has just been instantiated using the new operator, and it is not associated with a Hibernate Session . It has no persistent representation in the database and no identifier value has been assigned.

What is the use of transient keyword in Salesforce?

Use the transient keyword to declare instance variables that can't be saved, and shouldn't be transmitted as part of the view state for a Visualforce page.

Why static fields are not serialized?

In Java, serialization is a concept using which we can write the state of an object into a byte stream so that we can transfer it over the network (using technologies like JPA and RMI). But, static variables belong to class therefore, you cannot serialize static variables in Java.
