1. Using Eclipse IDE

In Eclipse IDE, move the mouse over the class name implementing the Serializable interface, or click on the Serialization class and press CTRL + 1.

2. Using IntelliJ IDEA

In IntelliJ Idea, we have to manually enable the auto-generate serialVersionUID option. You can find the detailed explanation here.

3. Using built-in JDK command

JDK provides the built-in command to generate a serialVersionUID automatically. The command is serialVer.

Syntax

serialVer className

In the below example we are generating the serialVersionUID of the HelloWorld class. Make sure the HelloWorld class is implementing the Serializable interface.

Last but not the least, you can use the serialVersionUID=1L. It will be enough for most of the cases.

Syntax

private static final long serialVersionUID = 1L;
