Casting an int to a string to work indexOf method

Question

I'm trying to see what interger value occurs in a specific token.
For examplethe token: "6-" the integer 6 occurs.
But I have to pass the indexOf method a string.
if (tokenCountdown == 0)
     while(gotGoals != 1)
          String(varGoal);
          if (tokenStr.indexOf(varGoal) = -1)
               goalsScored = (int)(varGoal);
               gotGoals = 1;
               varGoal++;
     }Any ideas on how to get around this?

Answer 1

I have tokenised a text file and the specific token
can contain a string of form XX-
X being interger values.
What I want to do is extract whatever integer value is
XX and store it in a variable.
Again, not clear. In "XX-X", are "XX" and "X" both integers? As in "12-3" and you want to extract "12" and "3"?
Is the first int always 2 digits and the second always one? In short, what, precisely, are the invariants in terms of lenght, position, etc.?
You reckon I cant use indexOf? What will you do indexOf on? If it's always "somenumber-someothernumber" then you can use indeOf("-") to find the split point.
What method can I use?
subString?You could use that in combination with indexOf("-"), yes.
Or you could use StringTokenizer, or String.split, or regex if it's actually more complex than I've been assuming. Assuming it's always "num1-num2", but num1 and num2 are not fixed length (e.g. couuld be 1 or 2 digits) StingTokenizer is probably the simplest.
If num1 and num2 are a fixed number of digits, you could just use substring, since you know exactly which positions you want.
Ultimately, which is best depends on your constraints. What's variable, what's fixed, how much flexibility you need.
