+#### Renaming Types in Java
+
+You might also want to rename the type of the entity. For this you can use annotation `@cds.java.this.name` to specify alternative name for the  accessor interfaces and [static model](./cqn-services/persistence-services#staticmodel) interfaces. This annotation can be used only on definitions and is ignored everywhere else.
+
+See the following example:
+
+```cds
+@cds.java.this.name: 'MyJavaClass'
+entity Class {
+  key ID: String;
+}
+```
+
+```java
+@CdsName("javaNames.Class")
+public interface MyJavaClass extends CdsData {
+  String ID = "ID";
+
+  @CdsName(ID)
+  String id();
+
+  @CdsName(ID)
+  MyJavaClass id(String id);
+
+  // rest of the interface
+}
+```
+
+In contrast with the annotation `@cds.java.name`, the annotation `@cds.java.this.name` does not rename projections of the annotated entity. If you want to rename chain of entities, you must annotate each of them individually.

 #### Entity Inheritance in Java
 
 In CDS models it is allowed to extend a definition (for example, of an entity) with one or more named [aspects](../cds/cdl#aspects). The aspect allows to define elements or annotations that are common to all extending definitions in one place.
