Prompting the user to enter a valid value in an applet

Question

hi everyone!
i have this code and i want to prompt the user to set a value<1000.
this doesnt work.if i enter a value <1000 the input dialog appears again.
whats wrong?
public void init()
   String j = JOptionPane.showInputDialog(null, "Enter a number less than 1000 but greater than 0");
   int i = Integer.parseInt(j);
   while(i>1000||i<1)
      String k = JOptionPane.showInputDialog(null, "Enter a number less than 1000 but greater than 0");
      int y = Integer.parseInt(k);
....code executed while i<1000 or i>0

Answer 1

Your while is looping on i, but inside you're setting
y not i. This should work:
do {
String k = get input from option pane
int i = Integer.parseInt(k);
} while (i > 1000 || i < 1);
In BinaryDigit's code, you won't have access to "i" after the loop. Declare it outside the loop (as you had it).
int i = 0;
do {
String k = get input from option pane
i = Integer.parseInt(k);
} while (i > 1000 || i < 1);
