Not really sure how you want to add them, as int’s or Strings, but remember they have to be Objects.
class Inp {
public void scan() {
Scanner sc = new Scanner(System.in);
HashMap<Integer,Integer> map = new HashMap<Integer,Integer>();
while (true) {
String sr = sc.nextLine();
String[] tk = sr.split(" ");
Integer key = 0, value = 0;
try {
key = Integer.parseInt(tk[0]);
value = Integer.parseInt(tk[1]);
}
catch (NumberFormatException e) {
break;
}
map.put(key,value);
}
}
public static void main(String[] args) {
Inp inp = new Inp();
inp.scan();
}
}
VERRRRYYYY long winded but you get the idea. Put in anything besides an integer to break out of the loop. Didn’t know what you wanted.
