In Java, the serialVersionUID is a unique identifier used during the serialization and deserialization process. When a class implements Serializable , it's good practice to declare this static final field to ensure version compatibility.
private static final long serialVersionUID = 1L; For more precision, compute a unique value using the serialver command-line tool (JDK included): generate serialversionuid in vscode
"serialVersionUID": { "prefix": "svuid", "body": "private static final long serialVersionUID = ${1:1L};", "description": "Generate serialVersionUID" } Now type svuid + Tab inside your class. For most projects, using 1L is perfectly fine. If you need a value based on class structure, run serialver manually or install a dedicated extension. Always remember to make the field private static final long . In Java, the serialVersionUID is a unique identifier
