a = Integer.parseInt(firstHalf) + 1;
sb.append(a);
sb.append("/");
for(int j = i; j < 13; j++) {
b = Integer.parseInt(otherHalf) + 1;

Not sure what you're trying to do, but you can use this to print out values :
List<String> session = new ArrayList<>();
for (int i = 2017; i < 2030; i++) {
session.add(i + "/" + (i + 1) + "n");
}
System.out.println(session);
You don't need to use a nested loop or even a StringBuilder.

You do not need two for loops. Instead you can do following:
public List<String> getSessions() {
int a = 2017;
int b = 2018;
List<String> session = new ArrayList<>();
while (b <= 2030) {
StringBuilder sb = new StringBuilder();
sb.append(a);
sb.append("/");
sb.append(b);
session.add(sb.toString());
a++;
b++;
}
System.out.println(session);
return session;
}
