the question had been asked me in interview. i know primitive types converted wrapper class object store in data structure. but interviewer asked me dont want wrapper class object , should stored primitive type. how can that? using java's collection api, cannot in sensible way. of course implement list or map interfaces , decide store primitives instead of objects cause headache anyway. java's collection interfaces based on objects (generics don't play role in that), cannot have add or remove method takes int argument. let's have own implementation of list<integer> stores int instead of integer defined interface, write this: list<integer> intlist = new myprimitiveimplementation<>(); intlist.add(42); now happens primitive int 42 gets autoboxed integer object because collection interface defines add method add(integer e) . implementation unboxing integer object again primitive back. so, there's no point. either ser...

apologies super-basic question, i'm grappling simplest thing: how change color of lines, in mike bostock's simple multi-series d3 line chart . (i know – i'm idiot.) i've spent hours fiddling different solutions, rummaging through d3 documentation , googling furiously, i'm failing horribly. in example chart, mike bostock uses d3's built-in "category10" color scale, per line of code: var color = d3.scale.category10(); but suppose, instead of built-in scale, wanted line austin blue, line new york red, , line san francisco green. should simple enough, right? define custom color scale: var color = d3.scale.ordinal() .domain(["new york", "san francisco", "austin"]) .range("#ff0000", "#009933" , "#0000ff"); i thought might trick – but turns series black. so... total failure. i'm sure i'm missing obvious here – i'm stuck. i've tried css styling each series appendi...
