I was self learning some C++, however I'm going to start college in the fall, and the college teaches only Java, so I figured it would be in my best interest to drop C++ for now, and start Java. So, I have PDFS and Books for C++, I was looking for some self learning tools for Java, PDFS, Tutorials, Compilers. I like Eclipse. Is this a good Compiler, should I use something else, or is it all a matter of opinion? Any suggestions for software / learning tools I should have would be greatly appreciated.

Hello!

I have gotten back into my programming groove, after a small break, however I never got very far. I switched from Java to C++, a lot of people suggested I do so, and on top of that, a friend at work uses C++, I hope to eventually go back and learn how to perform the operations in Java, however for now I am sticking with C++.

Anyway, enough about my lifes story! Haha.

I've been reading Stoustrup's Programming Principles and Practice using C++, and I was doing one of the 'drills', when I noticed how ugly the command prompt gets with all the cin and cout in the same window.

I looked around however, I didn't see anything that was readable at my level related to my question.

The Question!

How do I request the inputs to be in a popup / child window instead of the parent  / main window, to keep the program cleaner.



( Incoming Code, this is what I have made so far, and I know I don't need to include all of the #include's that I did... But they make me feel happier about my life, which is a good enough reason to have them!)

#include<iostream>
#include<algorithm>
#include<string>
#include<vector>
#include<cmath>
using namespace std;
inline void keep_window_open() { char ch; cin>>ch;}

int main(){

  cout<<"Please enter the name of the person you wish to write to.\n";
  string first_name;
   cin >> first_name;
  cout<<"Dear" << " " << first_name <<",\n";
  cout<<"How are you?\n";
  string first_response;
  cin >> first_response;
  cout <<"I miss you.\n";
  cout << "Please enter the name of our friend.\n";
  string friend_name;
  cin >> friend_name;
  cout << "Have you seen" << " " << friend_name<< " " << "lately?\n";
  cout << "Enter the sex of" << " " << friend_name << " " << "as a 'm' or 'f'.\n";
  char friend_sex = 0;
   cin >> friend_sex;
   if (friend_sex == 'm'){
    cout<<"If you see" << " " << friend_name <<" " << "please have him call me.\n";
   }
   if (friend_sex == 'f'){
    cout<<"If you see" << " " << friend_name <<" " << "please have her call me.\n";
   }
   cout<< "Please enter recipients age\n";
   int age;
    cin >> age;
    if (age != 0 && age < 110)
    {
    cout << "I hear you recently had a birthday, and you are now" << " " << age << " " << "years old.\n";
    }
    else
    {
cout << "You're kidding!";
    }
    if (age ==17)
    {
cout<< "Next year you will be able to vote!";
    }
    if (age > 70)
    {
cout << "I hope you are enjoying retirement!";
    }
    cout << "Next year you will be" << " " << age+1 << ".\n";
    cout << "Yours Sincerely\n";
    cout << "\n";
    cout << "\n";
    string writers_Name;
cin >> writers_Name;
cout << writers_Name;
  
  keep_window_open();
}




Thanks!

Hello. I'm looking to learn Java on my own. I have the textbook "Big Java 4th edition" by Cay Horstman, however seeing as we're on the internet, is there anyplace that can also really teach me a good deal? I'd greatly appreciate any and all tutorials, especially stuff that starts out easy and continues moving into harder and harder stuff. Also, I am attempting some Game Design (I don't want to be just a game designer, however I felt it was a great way to start learning) so anything java related in that area would also help.

Furthermore, and tips, or advice regarding Java would be greatly appreciated

Regards,

Hey. I was going to college taking a bit of first year Java until I was unfortunately unable to continue going to college (Lack of motivations on top of actual phsyical barriers, like my car dieing, and my internet going out for 2 weeks(which dropped me from straight A's to C's and below, because of when it hit)) anyway, I've been trying to learn Java on my own, as I still have my college textbook, and a desire to learn.

I've been reading Tutorials, and looking around for information, Oracle is amazing. Anyway. Here's the Compiler error.

Game.java:32: error: cannot find symbol
private BufferedImage image = new BufferedImage(WIDTH, HEIGHT, BufferedImage.TYPE_INT_RBG);
^
symbol: variable TYPE_INT_RBG
location: class Game
1 error



I'm not sure why I'm getting this error, and I feel like I either forgot to import something, or I am missing something from my java libraries. If anyone could help with this, I would greatly appreciate it.
