How do you implement B-Tree in java with a GUI.
I'm new to Java Algorithms and want to know how to implement this data structure in code.
...Suppose I have a have java.io.InputStream object, how should I process that object and produce a
String from it in java?
I would need a function which reads InputStream and output it as a String
thanks
...The answer is this-: Because we can't declare a field of different data types within a same index in different document types.
Say there's an index called "college".
Then there are document types called "student" "teacher" "administration" "staff".
What problem would occur if we allow this?
Books and documentations are saying that if a field called "date_of_join" is given a "text" data type in "student", then we can't give "date_of_join" as "date" data type in "staff".
It says that it's due to the way Lucene is.
This is because of the way Lucene maintains the field types in an index. As Lucene manages fields on an index level, there is no flexibility to declare two fields of different data types in the same index
But this is not clear without an example(of how lucene is storing index). Can you guys clarify this?
I know that lucene stores inverted indexes though. But still I'm not clear.
...I am new to java programming and Eclipse, so I would like to know how can I comment or uncomment Java and HTML Code shortcut in Eclipse IDE using Keyboard shortcuts, easily and quickly.
