algorithm - When is a Binary Tree better than a B-Tree? -


when storing binary tree or b-tree on secondary storage device such disk or tape, binary tree ever have advantage on b-tree?

i asked on assignment "when b-trees have advantage on binary trees?"

what have come b-tree better because requires less frequent disk access (reads more data per node access), , jumps less nodes final node. way question worded, implies there point binary tree have advantage on b-tree. so, is there point when binary tree better (more efficient) b-tree when stored on secondary storage?

it not correct compare sorted tree (b-tree) , simple binary tree, not equal. suppose mean binary search tree.

b-tree designed efficient when data stored on relatively slow storage. example when load or save data file system cluster size 4kb doesn't matter how of data in range 0..4kb need, take same time read 1 byte or 4kb , take time. b-tree keeps in mind fact , use it. in normal/general usage scenarios more efficient use b-tree (from point of view used space , performance).

java.util.scanner - How to read and add only numbers to array from a text file -

i'm learning java , have question regarding reading file want read numbers file contains strings well. here example of file: 66.56 "3 java 3-43 5-42 2.1 1 and here coding: public class test { public static void main (string [] args){ if (0 < args.length) { file x = new file(args[0]); try{ scanner in = new scanner( new fileinputstream(x)); arraylist<double> test = new arraylist<>(); while(in.hasnext()){ if(in.hasnextdouble()){ double f=in.nextdouble(); test.add(f);} else {in.next();} } catch(ioexception e) { system.err.println("exception during reading: " + e); } } my problem add 66.56,2.1 , 1 doesn't add 3 after "3 or ignores 3-43 , 5-42 can tell me how skip strings , add doubles here? thanks all said 3 ie; "3, 3-43 , 4-42 strings either u read string , split , check number @ " , - or put in space between characters , integers. jvm after compilation tre...
