input

[Bob Gucco]

How can I accomplish ignoring "enter" key.
Suppose by initializing of my variables "n1, n2, desc" after
-
-
System.out.print("Number 1 :");
-
-
instead of putting some data first
I hit "enter" by accident - I would like my program to continue without throwing an exception. What can I do about it?
InputStreamReader reader = new InputStreamReader(System.in);
BufferedReader input = new BufferedReader(reader);
System.out.print("Number 1 :");
String n1 = input.readLine();
int number1 = Integer.parseInt(n1);
System.out.print("Number 2 :");
String n2 = input.readLine();
int number2 = Integer.parseInt(n2);
System.out.print("Description :");
String desc = input.readLine();
Thanks

Hi Bob,
How about using a loop until the user has typed a string:

  System.out.print( "Input Here: " );
  do
  {
    s = input.readLine();
  } while( s.length() > 0 );
  int number = Integer.parseInt( s );

Regards,
Manfred.

How about if I want by clicking lets say "M" do something.
How can interpretor find out if it is "M" or "m"?

How about just checking for it?
if( s.equals( "M" ) )
{
// Upper case M
}
else if( s.equals( "m" ) )
{
// Lower case m
}
