Strings assign with scanner

Question

I have 4 Strings and i need to assign them.
If there is no next line a exception for eachstring should be thrown.
Can i do that anyhow with a loop instead of 4 if else statements?

Answer 1

You could store your strings as an array:

String[] strings = new String[4];
Scanner sc = new Scanner(/* ... */);

int index = 0;
while (sc.hasNext()) {
if (index >= strings.length) break;
strings[index] = sc.next();
index++;
}
// beware:
// if this loop terminates because hasNext is false, the remaining strings will be null

// Access strings as you normally would access an array
String firstString = strings[0];
// ... and such
