The corrected file is as follows:
import javax.swing.JOptionPane;
/*
* To change this template, choose Tools | Templates
* and open the template in the editor.
*/
/**

public class GetInputFromKeyboardJOptionPane2 {
public static void main(String[] args) {
String name = "";
name = JOptionPane.showInputDialog ("Please enter your name");
String msg = "Hello " + name + "!";
JOptionPane.showMessageDialog (null, msg);
String age = "";
age = JOptionPane.showInputDialog ("Please enter your age");
String ageStr = "Your age is " + age;
// age was assigned here as string.
JOptionPane.showMessageDialog (null, ageStr);
int ageint;
ageint = Integer.parseInt(age);
if (ageint>100){
age = "Hello "+name+"! Your age is "+age+". You are old";
JOptionPane.showMessageDialog(null,age);
}else{
age = "Hello "+name+"! Your age is "+age+". You are young";
JOptionPane.showMessageDialog(null,age);
}
}
}
Thanks & Regards,
Shyam
