Question

I am experiencing difficulties with an expression that should result in showing or hiding a band in an iReport.

These are variables that I have:

Integer mainGroupInt = Integer.valueOf(5);
Integer subGroupInt = Integer.valueOf(5);
Boolean showDetailGroup = Boolean.valueOf(false);

The result must be a Boolean, so I tried the following:

mainGroupInt.intValue() != 0 && subGroupInt.intValue() != 0)) || (mainGroupInt.intValue() != 0 && showDetailGroup)

This is thus not working, I get the following error:

The expression of type boolean is boxed into Boolean

I’m overthinking this one but I cannot solve it.

Thanks for your help.

Answer 1

Are you looking for…

showDetailGroup = Boolean.valueOf( (mainGroupInt.intValue() != 0 && subGroupInt.intValue() != 0) || 
                                   (mainGroupInt.intValue() != 0 && showDetailGroup.booleanValue()) )

If not, I don’t understand your question. The above code returns a Boolean representing the value of the boolean expression. See Java Boolean.valueOf() and Boolean.booleanValue() docs.
