Question about Java

[ButterflyBlood]

OK, let's say I have a basic text file with one sentence on it. How do I get that sentence to be printed through the program?

I know this code could input it:

public static void main(String[] args) {
try {
Scanner sc = new Scanner(new File("fileName"));
}
catch (FileNotFoundException ex) {
System.exit(1);

But then how do you print the contents of the file put in?

1. Check this out:

2. have looked at it, unfortunately

it only tells how to input a file, not print the contents.

3. self-delete

4. Using your code, couldn't you do something like this :

public static void main(String[] args) {
try {
Scanner sc = new Scanner(new File("fileName"));
System.out.println(sc.nextLine());
sc.close();

}
catch (FileNotFoundException ex) {
System.exit(1);

I used the link I posted earlier as reference

-hope this helps, haven't worked with Java in some time

7. another question though

that only prints the first line of the file. How do you get it to print every line? I assume it could be done with some sort of while loop, but only if the program knew how many lines they were in the file already. Is there any way to get that?

8. You could do it with a loop but you don't have to know

how many lines there are in the file beforehand. The Scanner class has a method that looks to see if there is another line in whatever you are scanning:

while ( sc.hasNextLine() )
{
do want you need to do


}

if there are no more lines it should break out of the loop

//close the scanner here

The link I posted is a very good reference, but it takes a while to search what you are looking for:

9. thank you

I have read those documents and my text book, the problem is they often don't describe the type of things you need to do next to each other and you have to keep searching.
