let dataset.getYMax return zero in case there are no items in the dataset instead of -infinity - anylogic

I'm adding data to dataset when a condition is true, then I'm using getYMax() to calculate the maximum value in the dataset. However, if the dataset is empty (no items have been collected) it will return -infinity. Is there any way to make getYMax() return 0 instead of -infinity?

Thank you

Solution

  • Sure. Use a separate function returning a double and taking the dataset as an argument, call it f_getDSMax():

    if (myDataSet.size() == 0) {
    return 0.;
}
return myDataSet.getYMax();

    Or you do it in 1 line:

    myDataSet.size() == 0 ? 0. : myDataSet.getYMax()
