- aeurielesn 13y agoFishy. If you are trying to prove a point there are definitely better ways to do it.
- macowar 13y agoJust try and compile this simple program: > println("System"); It gives this error: "At line undefined, the submission failed to compile with the error: Error: Sorry, but you may not use the keyword 'System'" This tool has a list of blacklisted words that can not appear in your source code.
- chromaton 13y agoOther banned strings include "forName", "Class" (uppercase only), and "Method".
- perimo 13y agoShameless plug: this seems like a good application for Doppio: https://github.com/int3/doppio https://github.com/int3/doppio The whole JVM lives in the browser, so you don't need to rely on hacks to "sanitize" user programs.
- kittybyte 13y agolooks really cool, but it seems very slow?

- TeeWEE 13y agoAh i still cant get his server down: try { Cl\u0061ssLoader loader = Thr\u0065ad.currentThread().getContextCl\u0061ssLoader(); Cl\u0061ss cls = loader.getParent().loadCl\u0061ss("java.lang.Sys"+"tem"); loader.getParent().loadCl\u0061ss("java.lang.reflect.M"+"ethod"); java.lang.reflect.M\u0065thod m = cls.getM\u0065thod("e"+"xit", int.class); m.invok\u0065(Integer.valueOf(1)); println(m); } catch(Exception e) { print(e); }
- vladimirralev 13y agoStuck at the combos with this one: void combos(String letters) { addAnswer(letters);addAnswer(""); for(int q=1;q<letters.length();q++) { combos(letters.substring(q)); combos(letters.substring(0,q)); } } It says it's no good, but it doesn't say why :(
- 6ren 13y agoMouse over the text "Returned the wrong result" at the bottom to see the test results. Move mouse right to view other test results. The background colour of the text indicates fail/pass, murky brown/green vs solid green. (Perhaps red would be better a better indicator for fail.) For yours, there are 5 tests, and your code passes one (test number 3).
