Thread: Need some help with substring please

Hi,
I am creating a seating plan generator for my computing coursework and need to separate a string into parts:

"Barn, Sam",10,AG,M,07.08.97
"Smith, Trevor James",10,GB,M,25.03.97
"Paddington, Kieran Simon",10,AG,M,10.09.96
"Benton, Rebecca",10,AT,M,31.10.96

It will be read in as ClassCodeString.
I need each of their names, Gender (M or F) and the last 6 digits(DOB).
The user will put in different students each time so the positions of the names, gender and DOB will change, but the symbols separating them will remain the same.

Any help would be greatly appreciated

I want to store the each person's name in an array, their genders in another, and their DOB in the last. I've tried using substring but it didn't work very well.
I have no idea what an API is so this probably in the wrong section, sorry.

I don't have any code for it because I have no idea how to do it, which is why I am here.

I need someone to show how I can make a program that takes the names and the gender for each of the students from the following:

"Barn, Sam",10,AG,M,07.08.97
"Smith, Trevor James",10,GB,M,25.03.97
"Paddington, Kieran Simon",10,AG,M,10.09.96
"Benton, Rebecca",10,AT,M,31.10.96

Well first of all I need to get the name between the speech marks and store that in an array. Then I need to find the second name and put that in the same array. and so on...
How would I do that?

Everything inside the speech marks is the name,
After 3 commas you will find a letter that represents the gender,
That is one person's information,
Once you hit the next speech marks it means you have reached the next person's information, and follow the previous instructions.

So would the charat method be like:

if(classCode.charat(0)==","){

}

When I try that I get an error saying "Incomparable types: char and java.lang.string"

It's a bit messy, but i tried to get the counter to work first. It's supposed to print out where the first speech marks are and where the second speech marks are. I get this error:
java.lang.StringIndexOutOfBoundsException: String index out of range: 12
The number at the end of the error is the number of characters the string I typed in was.

String ClassCodeString = ClassCode.getText();
 
boolean found=false;
int counterTemp1=0;
int counterTemp2=0;
 
for(int counter=0;ClassCodeString.length()>counter;counter++){
 
    found=false;
 
    if(ClassCodeString.charAt(counter)=='"'){
 
        counterTemp1=counter;
 
        for(;found==false;counter++){
 
            if(ClassCodeString.charAt(counter+1)=='"'){
 
                counterTemp2=counter+1;
 
            }
        }
        System.out.println("counterTemp1 = "+counterTemp1);
        System.out.println("counterTemp2 = "+counterTemp2);
    }
}

I did this:

int ClassCodeLength = ClassCodeString.length();

for(int counter=0;ClassCodeLength-1>counter;counter++){
...

But I'm still getting the same error

Sorry, I don't understand what you mean.
