Install Eclipse on Ubuntu
This article teaches you how to install Eclipse, the multi-language software development platform comprising an IDE and a plug-in system on Ubuntu.
1. If you haven’t installed Sun Java, install it by executing the command below in terminal:
sudo apt-get install sun-java6-jdk
2. To install Eclipse, use the command below in Ubutnu
sudo apt-get install eclipse
3. To make Sun’s Java the default Java
sudo update-java-alternatives -s java-6-sun
4. Edit the JVM configuration file
sudo -b gedit /etc/jvm
5. The command above will open up a file, add the line below to the top of the file opened, and then save and close the file
add the following to the top of the file
/usr/lib/jvm/java-6-sun
6. Eclipse by default won’t pick up JVM from java-common, so to solve the problem, we need to edit the java_home file in Eclipse,
sudo -b gedit /etc/eclipse/java_home
7. This will open up another file, insert the following line in as the first line:
/usr/lib/jvm/java-6-sun
Now it’s done!

string::size_type i = 0;
string::size_type j = s.find(c);
while (j != string::npos) {
v.push_back(s.substr(i, j-i));
i = ++j;
j = s.find(c, j);
if (j == string::npos)
v.push_back(s.substr(i, s.length( )));
}
}
int main( ) {
vector<string> v;
string s = "Account Name|Address 1|Address 2|City";
split(s, '|', v);
for (int i = 0; i < v.size( ); ++i) {
cout << v[i] << '\n';
}
