wildcard - Regular Expression for String *.java -



wildcard - Regular Expression for String *.java -

i writing programme finding number of occurences of java classes in log file.

i want count number of distinct times java class called. search should of form "*.java"

can help me regular look this?

a sufficient regular look [a-za-z_][a-za-z_0-9]*\\.java . regular look requires string start letter (or underscore), , go on number of letters or numbers (or underscores), follows java class name conventions. period double escaped \\ -- 1 escaping java escape \ in string, , sec regex matcher escape period (otherwise period special character meaning "any character").

this regular look fit task little improve asked precisely: .*\\.java (which .java preceded anything), because match entirety of line before ".java", leaving 'class names' "printing file myclass.java" instead of "myclass.java".

i seek look out (and seek out changes it) on online tool rubular.

Accessing MATLAB's unicode strings from C -

Accessing MATLAB's unicode strings from C - how can access underlying unicode info of matlab strings through matlab engine or mex c interfaces? here's example. let's set unicode characters in utf-8 encoded file test.txt, read as fid=fopen('test.txt','r','l','utf-8'); s=fscanf(fid, '%s') in matlab. now if first feature('defaultcharacterset', 'utf-8') , c engevalstring(ep, "s") , output text file utf-8. proves matlab stores unicode internally. if mxarraytostring(enggetvariable(ep, "s")) , unicode2native(s, 'latin-1') give me in matlab: non-latin-1 characters replaced character code 26. need getting access underlying unicode info c string in unicode format (utf-8, utf-16, etc.), , preserving non-latin-1 characters. is possible? my platform os x, matlab r2012b. addendum: documentation explicitly states "[mxarraytostring()] supports multibyte encoded characters...
