Note that you store the age (10) in the String age Then later you change the
String age to "Your age is 10" that is perfectly OK. But.. then you try to
parse the String age to an Integer and "Your age is 10" is not parseable to
an Integer..
What you have to do is to store the age and the display string "Your age is
..." in different Strings.
Hope this will explain

String age = "";
age = JOptionPane.showInputDialog ("Please enter your age");
*age = "Your age is " + age*;
JOptionPane.showMessageDialog (null, age);
*int ageint = Integer.parseInt(age);*
