Read a string from the standard input (System.in), then parse it to integer (Integer.parseInt()).<br>
<br>
Good luck. Bye, Otto.<br>

There is also a class for keyboardInput that has a method readInt();<br>

Not!<br>
The readInt() always reads four bytes (32 bit). If you type<br>
1234, the result will be $31*65536+$32*256+$33*16+$34 (ASCII code*2^...), and not 1234. The readInt() is suitable only DataInputStream-s (and descendants).<br>

HI,<br>
Why not to read a line from the keyboard<br>
<br>
BufferedReader br = new BufferedReader( new InputStreamReader( System.in));<br>
String str = br.readLine() ;<br>
<br>
and then <br>
<br>
int value = Integer.parseInt( str ) ;<br>
<br>
Hope it will help<br>
<br>
Regards.<br>
