i have made 2 classes in project in bluej , have link them making new field in main class of type of second class. what syntax this? i may interpreting question wrong but, assuming classes class1 , class2, can have class1 take in instance of class2 so: public class class1{ class2 otherclass; public class1(class2 otherclass){ this.otherclass = otherclass; } } now class1 has instance of class2 can play with. you may have class1 create class2 object instead of passing 1 so: public class class1{ class2 otherclass; public class1(){ otherclass = new class2(); } }

i have been looking @ various open source projects, , have bunch of files written in c have .inc file extension. far can tell, used header files. i thought standard convention use .h files header files , .c source files. so, there standard convention on when header file should .inc file rather being .h file, or these decided @ per project basis? (or looking @ weird projects use .inc ?) the standard convention use .h header files contain macro definitions , other declarations , .c c source files contain code , data definitions. in projects, code fragments stored in separate files , included in c source files macro tricks expand in different files or circumstances. sometimes, these files included multiple times in same source file. underscore special semantics attached such files, giving them different extension may useful hint. these files may have been generated part of build process: naming them may prevent confusion actual source files. look @ files came a...

newton’s method can used calculate p-th root of positive real number. write matlab function myrootp.m calculates a^(1/p) a> 0 , positive integer p. function should stop when abs((xk^(p)/a)-1)<10^(-15). i used following code cannot find error: function root1 = root1( a,x0,p) xk=x0; fd= p*xk^(p-1); f=(xk^p)-a; if a<0 disp('error:a must positive , real') else k=1:p if abs(xk^p/a-1)<10^(-15) return disp('error'); else xk1=xk-f/fd; xk=xk1; fd= p*xk^(p-1); f=(xk^p)-a; end end end root1 = xk; return end i'd point out unfamiliar algorithm finding nth root of number using newton's method . back problem, there 2 errors: there no such keyword then in matlab. rid of it. you'll want iterate until error specified. looping many times there power p , , it's highly possible algorithm can converge before then, or worst case require more iterations p ...

okay here's scenario, knowledge there 3 ways create web application traditional way: render html page server not sure: create api , let user's browser download javascript application (angular, react, ember) highly interactive application the future: isomorphic web app, render html client-side technologies (angular, react, ember) server. i'm planning use third way, due faster load page, problem right if create mobile application. my stack: node.js + react let if i'm planning go mobile, need duplicate same route , logic ? current problem app.get('/users', function(req, res) { res.render('index', { message: "hey im jack" }); }); app.get('/api/users', function(req, res) { res.json({ message: "hey im jack" }) }); is there way use 1 route serve both html , rest? you can send either html or json (in case of rest). the /api/xxx route syntax makes clearer path serves json. but can depend on clie...

i have .net web api deployed web app , trying connect mysql db on vm in virtual network, it's responding 500 internal server error. my vnet consists of 1 vm no dns or site-to-site configuration. the preview portal says vnet integration connected, certificates in sync , gateway online. i gave vm static ip address i'm using in web.config connection string, thinking requests routed through gateway vm, according general mysql log aren't connection attempts mysql server. the address gave vm within range of addresses being routed vnet, , setup endpoint on vm port i'm trying connect mysql on access rule allows connections, i'm not sure why connection doesn't appear getting through gateway vm. you may check link provides instructions on how connect azure app service - web app azure virtual network, can use resources visible within network itself: https://azure.microsoft.com/en-us/documentation/articles/web-sites-integrate-with-vnet/
