不使用Integer.ParseInt（）进行转换

Question

I have a problem that when I use Integer.parseInt in this context it doesn't convert my and somehow it even kick me out of loop so it dont't want to display for example System.out.print(1) after loop like everything was crashed but i have no error. Please help. That's a part of code which cause it. variable "input" is an Arrayl

for (int i=0;i<input.size();i++) 
{
    if(point>Integer.parseInt(input.get(i).split(":")[1]))
    {    
        input.set(i,highScore + System.getProperty("line.separator"));
        break;
    }               
} 

Answer 1

Have you verified that input.get(i).split(":")[1] gives you exactly a string that only contains digits?

Integer.parseInt(String s) throws NumberFormatException, so you should execute that code inside a try/catch block like this:

for (int i=0;i<input.size();i++) {
  try {
    int parsedValue = Integer.parseInt(input.get(i).split(":")[1]);
    // do whatever you want to do with parsedValue
  }
  catch(NumberFormatException e) {
    System.out.print("I caught an error!, what i was trying to parse wasn't a number");
    // or any other action you consideer that needs to be done when parseInt fails
  }
}

There is only one explanation (if you are sure that no exception is thrown): the input is empty. :)
