How To Get Program To Perform Tasks Listed In Text File

This has three different classes in a package and the program itself is supposed to read and perform operations obtained from a txt file. However, I'm not even sure how to get it to perform the operations from the text file. I know that it can read the file as I was able to get the program to print the text found in the file when I ran the program with a test print to make sure that all content was being read. However, I am clueless when it comes to how to get the program to look at the text as commands.

Here is the piece of code that I am not sure where to go from as far as telling the program to read the text and perform the tasks listed.

public static void doTVoperations(){
File operations = new File("operations.txt");
if(operations.exists())
try{
Scanner n = new Scanner(operations);
while(n.hasNext()){
String readOperations = n.nextLine();
String [] command = readOperations.split("[
]");
}
n.close();
}
catch (FileNotFoundException e){
System.out.print("Error...TV in need of repair!");
}
