Generics in view's method

[Former Member]

Hi

I am working in CE 7.2 and I want to declare a method that returns ArrayList<String>.

How is it done?

Hi Yuval,

You can simply create ArrayList return type. In the method which u pass & get parameter add the generics. I tried the below

example & it worked.

ArrayList<String> a = sample();

a.add("12");

public java.util.ArrayList sample( ) {

//@@begin sample()

ArrayList<String>asds= new ArrayList<String>();

return asds;

//@@end

}

Dear Yuval,

Please open the iview > method tab > new > method radio button > ENTER the name of method then click on button ... > select the Java native type > browse > search arraylist.

Hi Arun

Thank you for your reply.

The problem is not Arraylist but ArrayList<String> , supported as of JDK 1.5.

Moreover when I try to add the generic type <String> to a function that has been

declared as returning ArrayList, the compiler automatically removes the addition of <String>.

public ArrayList myFunc() should be declared as public ArrayList<String> myFunc()
