I have this kind of file structure

MALE:FooBar:32
FEMALE:BarFoo:23

Where I would want to identify the gender and age of person, <Gender>:<Name>:<age>

try{
 BufferedReader in = new BufferedReader(new FileReader("people.ser"));
 String s;
 
 while((s = in.readLine()) != null){
 
 String[] var = s.split(":");
 //var[0]=MALE etc etc
 addGender.add(var[0]);
 }
}catch(Exception e){
 e.printStackTrace();
}

• Is using a delimiter (like a : in this case) to split string considered a bad practice?
• What about using the array from the splitted string to store it in some place?
• Are there any alternatives and better file structure?

I have this kind of file structure

Where I would want to identify the gender and age of person, ::

try{
 BufferedReader in = new BufferedReader(new FileReader("people.ser"));
 String s;
 
 while((s = in.readLine()) != null){
 
 String[] var = s.split(":");
 //var[0]=MALE etc etc
 addGender.add(var[0]);
 }
}catch(Exception e){
 e.printStackTrace();
}

is it considered bad using a delimiter ":" to split the files? using the array from the splitted string to store it in some place? or are there any alternatives and better file structure?
