I'm not sure what your question is. If you're asking how to write a program like that, then show us where you're stuck, and I'm sure we can help out.

Please continue this discussion in the Java in General (beginner) forum.

"sudha sudha",

There aren't many rules that you need to worry about here on the Ranch, but one that we take very seriously regards the use of proper names. Please take a look at the JavaRanch Naming Policy and adjust your display name to match it.

In particular, your display name must be a first and a last name separated by a space character, and must not be obviously fictitious.

Thanks!

well, you can get the system time with...

System.getTimeMillis();

and you can scan the user's input with the Scanner in

java.util.Scanner;

but remember, if you get the user's time in seconds....

1 second = 1000 milliseconds...

and thats the value you'll need to be looking for if the user enter's

1 sec, and if they enter 1 min.

then you'll need to look for 60,000;

but you'll need to get a start time for the system...

and after the scan of the input....then say

if(startTime + System.currentTimeMillis() == userInput)
System.out.print("Time Reached!!");

because the system initially took time to execute the question...

or an easier way would be to pause the thread...

enter a time: 2 // seconds

enter a message to be displayed: times up!

in the main you could do this...



the system will sleep (pause) for 2 seconds..

then print to the screen "times up!"

Agree with Justin Fox about Thread(sleep). But you forgot to put in the Exception handling. Thread.sleep() declares a checked Exception, so you have to code itAnd the sleep method is static, so you don't need a Thread object.
