So I can't get this little snipit of code to work and I'm not sure why it wont...
String rawInput = JOptionPane.showInputDialog("Please enter the three side lengths seperated by spaces.");
double[] hold = double.parseDouble(rawInput.split(" "));
I have an idea to use another string array to put the values in initially then put them into the double array using a for loop and the double.parseDouble() but that seems overly complicated for what I want to do.
Your code fails to compile because rawInput.split(" ") returns an array of String objects. You need just one String object to pass to Double.parseDouble(). It looks like you'll need a loop, to iterate through the array that you get.
If only it was that simple. You will have to create a loop.
What I ended up doing was this:
String rawInput = JOptionPane.showInputDialog("Please enter the three side lengths seperated by spaces.");
double[] doubleHold = new double[3];
String[] stringHold = rawInput.split(" ");
for(int i = 0; i < 3; i++)
{
doubleHold[i] = Double.parseDouble(stringHold[i]);
}
I don't like how it works and think there must be a better way, anyone have that better way?
String rawInput = JOptionPane.showInputDialog("Please enter the three side lengths seperated by spaces.");
String[] inputs = rawInput.split(" ");
double[] values = new double[inputs.length];
for (int i = 0; i < inputs.length; i++) {
values[i] = Double.parseDouble(inputs[i]);
}
Try this!
