Question

I’m having problems reading in a text file with java. The text file has the following format:

String
String
String
String

Int 
Int
Int 
Int

With each String and int value having a new line character at the end and a blank line in between the stings and ints. I want to save each string value into a string array but I can’t quite figure out how to get the scanner to stop at the blank line. I tried various methods such as going until there is an int, going until the value of hasNext is ” “, and trying to just read the strings but nothing is working. Can someone provide anyhelp?

Not sure from your example if you have exactly 4 Strings and 4 Integers or more, so something like the following should work:

List<String> strings = new ArrayList<String>();
List<Integer> ints = new ArrayList<Integer>();

while(scanner.hasNext() && !scanner.hasNextInt()) {
    strings.add(scanner.next());
}
while(scanner.hasNextInt()) { // If you also want to store the ints
    ints.add(scanner.nextInt());
}
