Currently I got this code: The repository returns an Iterable, which I want to convert to a ArrayList. Beside that I want to convert each Entity to a POJO.
Hey if anyone has an idea I would be really thankfull. I'm in a Java stream and i would like to sort my list that i'll be returning. I need to sort the list via TradPrefis ( MyObject::getTradPrefix ). But this would be way too easy. Because i want to...
What do I need to do for the output to be the below?I looked into concat but as the javadoc explains, it just appends one after the other, it does not interleave / intersperse.
I have an url like: String url = "https://.../foo/a/555/data1";Goal: Transform the url to the string: a555data1
I have the following method (see below). The code is working but I got сomments that there is a lot of repeating and that I should use IntStream.
Is there a way to collect both matching and not matching elements of stream in one processing? Take this example:
I'm running against an issue:I've created this stream I need to map to a Map<String, Object>:I'm getting the following message, which I don't quite figure out:
I think all of the resources I have studied one way or another emphasize that a stream can be consumed only once, and the consumption is done by so-called terminal operations (which is very clear to me).
This is from the Stream interface from Oracle's implementation of JDK 8:and it is very easy to blow this up at run time and no warning will be generated at compile time. Here is an example:
Can anyone point to a official Java documentation which describes how many times Stream will invoke each "non-interfering and stateless" intermediate operation for each element.
