I am trying to make a JOptionPane get an input and assign it to an int but I am getting some problems with the variable types.
I am trying something like this:
Int ans = (Integer) JOptionPane.showInputDialog(frame,
"Text",
JOptionPane.INFORMATION_MESSAGE,
null,
null,
"[sample text to help input]");
But I am getting:
Exception in thread "main" java.lang.ClassCastException: java.lang.String cannot
be cast to java.lang.Integer
Which sounds logical yet, I cannot think of another way to make this happen.
Thanks in advance
Simply use:
int ans = Integer.parseInt( JOptionPane.showInputDialog(frame,
"Text",
JOptionPane.INFORMATION_MESSAGE,
null,
null,
"[sample text to help input]"));
You cannot cast a String
to an int
, but you can convert it using Integer.parseInt(string)
.
