I want to know how to provide array as argument without any name inside the annotation. The sample you shared doesn't showcase an array as parameter of annotation. — prit kalra, Feb 28 '19 at 07:19
Yes, the argument is of type Array. I don't see any such support without mentioning the name of the paramArray. — prit kalra, Feb 28 '19 at 07:51
Yea. I believe you can't achieve it directly using any constructor. Maybe you could try custom setter and getter methods and converting or casting to array — Mebin Joe, Feb 28 '19 at 07:53

Just annotate your JClass, and to add an array parameter, use the paramArray() method:

JDefinedClass testClass = codeModel._class("MyClass");

JAnnotationUse jsonSubTypes = testClass.annotate(JsonSubTypes.class);

jsonSubTypes.paramArray("value")
    .annotate(JsonSubTypes.Type.class)
        .param("value", MyClass.class)
        .param("name", "MyClass");

Generates:

@JsonSubTypes({
    @JsonSubTypes.Type(value = MyClass.class, name = "MyClass")
})
public class MyClass {


}
