Extracting a method

[utkuumur]

Eclipse Che is a very versatile server and cloud based IDE. But it lacks useful refactoring tools that other IDEs offer. To make the code more modular and readable developer may want to create small methods for code fragments and the easy way to accomplish this is using a refactoring tool called extract method. In order to add this tool, a shortcut will be added to refactoring submenu in assistant menu.

Screenshot from another IDE that presents this tool.

Advantages of using extract method

• More readable code
• Minimizes code duplication
• Isolates independent parts of code (Seperation of concern)

Simple example

void printOwing() {
  printBanner();

  //print details
  System.out.println ("name:  " + _name);
  System.out.println ("amount " + getOutstanding());
}

After extracting details part

void printOwing() {
  printBanner();
  printDetails(getOutstanding());
}

void printDetails (double outstanding) {
  System.out.println ("name:  " + _name);
  System.out.println ("amount " + outstanding);
}
