// For loop publicstaticvoidmain(String[]args){Scannerscan=newScanner(System.in);for(inti=1;scan.hasNext();i++){System.out.println(i+" "+scan.nextLine());}}
You don't have to use the == operator to compare with true since the hasNext method returns a boolean.
U shall read Scan.hasNext like this.... does "Scan" have next element ?
If it has, it returns TRUE, so while something is TRUE, keep it going. That's why you don't need any comparing.

Your for loop can be simplified:
You don't have to use the == operator to compare with true since the hasNext method returns a boolean.
In fact, you can shorten it even further (at a potential loss of readability) by including the print statement within the for loop:
Even shorter:
Good idea!
That's pretty sweet! Thanks.
That's not very readable code! A
whileloop is more appropriate.Thanks for a different a view.
Oh...thats great idea =))
what scan.hasNext do?
it checks,is the scanner has more tokens in its input
what does Scan.hasNext() exactly means??
And while in the for loop we are not comparing Scan.hasNext() ??

sorry for being late,scan.hasNext() means after getting one input sacanner will wait for the next input .
Thanks a lot for sharing your knowledge..
