Java beginner

[DarkDragon2K04]

So I have been learning java for almost a year now. Self taught. Using sites like udacity, sololearn and I have also been using the java for beginners jdk 8 revision. The problem is I have been doing all of this alone and when I reach a bump things get tough. So I came here wondering if there are other java learners or even gurus who are here who would like to join me maybe we could have like a session together once a week were I help you with what you don’t understand in Java and you help me with what I don’t understand like a little community but we have specific times when we come together to discuss. Please if you are interested please tell me down below so we can have further talks.

Typically if you post questions people are pretty quick in responding or helping solve the issues. 

 

Anything in particular you need help with now?

Yah. With the book I am on the chapter that talks about I/O and streams and I don’t get what streams are and also if using the java.io is better than using scanner objects for input. Still if you are willing to be part of what I talked about earlier I would love to know

Can't answer about Java specifics but streams are what the name suggests. It's a "stream" of data. Basically imagine it as being like a tape. It contains all the data and you can scroll through it like you would with tape.

 

pseudo code!

var stream = File.Load(path) //opens the file stream
var data = stream.Read(0,100) //start at 0 read 100 bytes

There can be different type of streams i.e file streams or memory streams, but in the end they behave pretty much the same. It's a stream of data you can then read byte for byte.

 

For example, if you'd like to extract data without the header, you can simply load the file in a stream, and scrip the header size and read till file end to have everything except the header. Hope that helps clearing what's a stream. Feel free to ask if you still didn't fully understand it (would be understandable I suck at explaining)

Thank you. Please if you know any java community that has something like a weekly meet up or you want to join one please inform me

What specific questions you have? I can answer something basics about the language but if you have questions regarding the usage of specific libraries, it is best to read up Oracle doc.
