View Replies View RelatedInvoke Some Methods In For Loop In Order To Print Some Info Stored In A List
Apr 28, 2014I am trying to invoke some methods in a for loop in order to print some info stored in a List. But for some reason, compiler pops a message saying "cannot find symbol - method getEmpID(). You are using a symbol here (a name for a variable, method or class) that has not been declared in any visible scope." But I am pretty sure that method getEmpID (as also getName(), getAfm(), and payment() ) have been declared as public.

Get Value From Address And Save It In Variable?
Mar 15, 2014I just started using java because i want to create a simple web service that will take some values from within a url and save those values in variables.
To be more specific:
For my project I use the Spring Tool Suite.
I want to be able to enter a URL in a browser.. something like "localhost:8080/test?name=Root". When I hit Enter a page will be displayed showing "Hello Root" if the name in the URL is Root or "Hello User" for any other name.
I accomplish that with this code:
Java Code:
String UserName = "Empty";
@RequestMapping("/test")
public @ResponseBody String username(@RequestParam(value="name")String name){
if (name == "Root")
UserName = "Hello" + name;
else
UserName = "Hello User";
return UserName;
} mh_sh_highlight_all('java');
My problem is that it if I enter Root as a name in the URL it doesn't recognize it and it shows "Hello User".
I tried Java Code: << if (name.toString() == "Root") mh_sh_highlight_all('java'); but no luck.
How exactly I should reform this code in order to make it work?
How To Get The Actual Computer IP Address
Jan 31, 2014I wrote a Chess game that uses socket to connect to another computer, and allow player vs player and player vs computer game sessions.
However, there is a problem which I noticed.
When you get the IP address of the computer in which the program is running, you are not getting the computer's actual IP, you are getting the Router's IP.
Is there a way to get around this.
So the problem is that when I go to another computer, located in a different house or lets say from my school, the program cannot connect back to my home IP, because it uses the router's ip, not the computer's ip I am running the server program.
Is there a way to get the Computer's IP, not the router's ip when summoning or invoking the get IP address method from the socket class?
When I say that the socket class is acquiring the router's ip, well that's done without my interfering...I don't know why it does that, it is somehow recognizing the router and not the computer.
The thing is that the server program is written that any client program is able to connect to the home server.
But when I run the program from a different location other than the current home, the sockets don't connect because it is somehow recognizing the router's ip not the computer's ip.
