17. Launch an HTML file in the default browser

import org.eclipse.swt.program.Program;
public class MainClass {
  public static void main(String[] args) {
    Program.launch("index.html");
  }
}

17. Look up which program to use

import org.eclipse.swt.program.Program;
public class MainClass {
  public static void main(String[] args) {
    Program program = Program.findProgram(".html");
    program.execute("index.html");
  }
}

17. Run the appropriate program for that data file and load the data file into the program.

SWT has a Program class representing programs and their associated extensions.

17. Show the extensions on the system and their associated programs

import org.eclipse.swt.program.Program;
public class MainClass {
  public static void main(String[] args) {
    String[] extensions = Program.getExtensions();
    for (String s : extensions) {
      Program program = Program.findProgram(s);
      if(program != null){
        
        System.out.println(s+ ":"+program.getName());  
      }
      
    }
  }
}
