Hi, thanks for the video. HashMap also has a constructor that allows setting the initial capacity. What's the difference?
@jwmeyling 4 күн бұрын
That capacity of the HashMap is not equal to the expected size, one needs to consider the load factor as well. Capacity is the number of buckets in the map, not the number of entries. This confusion is now eliminated using the new utility method.
@Muescha 5 күн бұрын
char == 'l' is fine here, but be cautious of a common pitfall: if it’s a string, you need to use .equals.
@ghadifreiha9883 5 күн бұрын
A much better method I'd argue is to call Collectors.groupingBy(...) and then just call the map.get("l").size()
@alfagroupkz 5 күн бұрын
I just didn't get it. Why the hell l == 'l' do what we expect?
@kilianbalter 5 күн бұрын
The naming is a bit confusing maybe. I feel c -> c == 'l' would be better. The c in this case is just the individual characters coming from the char stream. Then we check if they're equal to the character l. The filter function then only lets all the l's through and they're counted.
@bienadam 4 күн бұрын
The naming is confusing. When I was recording, I thought "l" was a good name to search for the actual "l" character. In a project, I would call it "character" or "current". Thank you all for your feedback and comments!

@goodstuffsonly2545 11 күн бұрын
Is it batter to use fallback for null safety than orelse ?
@bienadam 9 күн бұрын
The orElseGet method calls the fallback only when needed. orElse eagerly calls the fallback and "caches" the value to use when needed. This can be critical for expensive operations such as calling external systems. Sometimes you may want to get a "fresh" value if it is not available. Then you need to use the orElseGet method. Thanks for your comment!

It will as soon as the first element is generated, since streams are pipelines operating on each element, not on all elements by steps

@azekilldiablo9315 12 күн бұрын
A number used by the Random function to create the "Random" sequence. Think of a number you input in a mathematical function!

@azekilldiablo9315 if we don’t give any seed, he said java will choose a random seed. What seed does it use to do that then? 🤔
@azekilldiablo9315 7 күн бұрын
@@MyzticBean I have no idea, you would have to look that up in details. My guess is it's using some java library to generate that one seed number (with a fixed seed someone chose at some point, some long string of number).
@Beesman88 2 күн бұрын
@@MyzticBean most pseudorandom generators use time as seed or part of seed. That's why if you loop and gen random numbers fast - .next will work as expected. But creating new instance of random in your loop will very often give you same numbers in a row - because multiple instances used the same seed, because it goes from time.

What's the advantage of this? Env vars are mapped into the process memory at process creation, so accessing them is simply reading a bit of memory of the process, I don't get how copying them is useful...
@bienadam 18 күн бұрын
System.getenv is just one example of a configuration. We could read a configuration from a file instead, which would make more sense in this context. But even with environment variables, the implementation depends on the chosen strategy: fail fast vs. eager loading. Thanks for the comment!
