Can I put C# and Java code in the same file to make porting my code easier? -

-

i porting code c# java. i'm finding it's easy miss code or make other mistakes. i'm thinking if can have both versions of code exist in same file, cut down on these mistakes. edit 1 file, 2 parts of file.

if java had pre-processor c#'s (i know projects available allow this), write this:

#if c_sharp namespace mymath {     class naivefib     {         public int run(int n)         {             if (n == 0) return 1;             if (n == 1) return 1;             return run(n - 1) + run(n - 2);         }     } } #elif java package mymath;  public class naivefib {     public int run(int n)     {         if (n == 0) return 1;         if (n == 1) return 1;         return run(n - 1) + run(n - 2);     } } #endif

i still have problem ide recognizing file contains compilable code given java files named *.java , c# files named *.cs. looks can have visual studio think *.java files c# files if check right settings. wouldn't have make changes java ide (eclipse).

is possible? , idea or more trouble it's worth?

i idea good, code hard read. mess. maybe if have simple codebase... in reality result big chaos!

you maybe spend lot of time looking @ wrong code, scrolling n down , getting more confused. clean code in files have focus, when open java project know work java. , when open c# know c# etc.

do java branch , c# branch of code. more easy maintain , keep clean.

think of situation want upgrade environment, why wasting time/money recompile java code while upgrade c# code, etc!

will port php, ruby, perl, python etc in same files ?

just let programmers open code want see , work with, separate files!

some java programmers might jump out of window when see c# code! thought it? ;)

i use sonar plugin executes if activated in maven profile. sonar runs on every compile. the problem build fail other team members not have sonar application installed locally. pom.xml checked in team members same copy including sonar configuration, don't want them modify purpose of disabling sonar (they might inadvertently check modified copy in). please advise how configure maven (.m2/settings.xml) and/or pom.xml sonar feature can enabled/disabled local profile. here sonar configuration in each project's pom.xml: <plugin> <groupid>org.codehaus.mojo</groupid> <artifactid>sonar-maven-plugin</artifactid> <version>1.0</version> <executions> <execution> <id>make-sonar</id> <phase>compile</phase> <goals> <goal>sonar</goal> </goals> </execution> </executions> ...

python - TypeError: can only concatenate tuple (not "float") to tuple -

i'm new python, question might easy, anyway, patience: as trying call newton-raphson method calculate implied volatility in black-scholes formula call/put option pricing, first thing is, newton method in scipy.optimize seems calculate function's zeros, in black-scholes formula, want function's value option price, not zero. (i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...

java - What is the difference between String. and String.this. ? -

this question has answer here: meaning of .this , .class in java 2 answers i'll straight point. im still learning bit of syntax , want know difference between code is code a: public class buttonz extends jbutton{ public buttonz(){ settext(new string(string.valueof(i))); } } please ignore fact i undeclared, not lost. code b: public class buttonz extends jbutton{ public buttonz(){ settext(new string(string.this.charat(i))); } } what don't yet understand difference in typing string.this , string. i under assumption when use dot operator on class accessing it's static methods(and/or variables if they're not hidden). i have studied little bit , have concluded when using string. accessing string static methods.. when using string.this. i'm accessing methods class buttonz extendi...
