I can't figure out how to use variables in HTML, string is a variable in this case.
JOptionPane.showMessageDialog(null,"<html>Error #1<br> + string +</html>","Error",JOptionPane.PLAIN_MESSAGE);
this output: Error #1 + string
JOptionPane.showMessageDialog(null,"<html>Error #1<br></html>" + string ,"Error",JOptionPane.PLAIN_MESSAGE);
this output: Error #1
is there a way to use string variables in HTML?
Do you want something like
"<html>Error #1<br>" + string + "</html>"
?
If you want to concatenate the string variable to the html you have there, it must be outside the quotes, otherwise it will be treated as a literal, as in your example.
JOptionPane.showMessageDialog(
null,
"<html>Error #1<br>" + string + "</html>",
"Error",
JOptionPane.PLAIN_MESSAGE);
Though note that logically JOptionPane.PLAIN_MESSAGE should be JOptionPane.ERROR_MESSAGE.
You need to do: "<html>Error #1<br>" + string + "</html>"
A string literal in java consists of zero or more characters enclosed in double quotes. So anything satisfies this condition will also be regarded as string too. You will need to close the String before appending the string.
So if the string = "Hi to stack":
Then "<html>Error #1<br>" + string + "</html>" will result in:
"<html>Error #1<br>Hi to stack</html>"
