Hey all I have this code. I want to delay my program for a few seconds and display "scanning..."
Here's what I have. This compiles but doesn't delay anything
if (i==1){
try {
Thread.sleep(1);
} catch (InterruptedException ie)
{
System.out.println("Scanning...");
}
}
thanks in advance I have int i = 1 before obviously
If you want to pause then use java.util.concurrent.TimeUnit
:
TimeUnit.SECONDS.sleep(1);
To sleep for one second or for 10 minutes
TimeUnit.MINUTES.sleep(10);
Or Thread Sleep
try
{
Thread.sleep(1000);
}
catch(InterruptedException ex)
{
Thread.currentThread().interrupt();
}
see also the official documentation
TimeUnit.SECONDS.sleep()
will call Thread.sleep
. The only difference is readability and using TimeUnit is probably easier to understand for non obvious durations.
but if you want to solve your issue
int timeToWait = 10; //second
System.out.print("Scanning")
try {
for (int i=0; i<timeToWait ; i++) {
Thread.sleep(1000);
System.out.print(".")
}
} catch (InterruptedException ie)
{
Thread.currentThread().interrupt();
}
