Question

I have static java methods which I add to javascript with this method:

public void addJavaMethod(Method method)
{
    try
    {
            FunctionObject fo = new FunctionObject(method.getName(), method, m_scope);
            FunctionObject.putProperty(m_scope, method.getName(), fo);
    }
    catch(Exception e)
    {
        e.printStackTrace();
    }
}

I always use the object class for parameters in these methods because it otherwise comes up with errors, for example:

instead of

static void setSomeFloatValueHere(float value){}

I use:

static void setSomeFloatValueHere(Object value)
{//convert this object to a float}

With booleans I can do a direct cast:

static void setBoolean(Object b){someBooleanObject = (Boolean)b;}

But with int,float,long,double, etc, I cannot do this.
I receive an error:

org.mozilla.javascript.Undefined cannot be cast to java.lang.Integer

How can I get this to work with those types as well? and possibly other non primitive type objects?
Thanks

Answer 1

Your object is probably not an Integer, but rather Number which has an intValue()

You can check the actual type by using value.getClass().getName().
