Help with File reading

Hi friends,

I have a file with mixture of strings and integers like this

Code:

---

aaaa 1
bbbb 2
cccc
dddd 3 eeee 4

---

I know exactly where the string or an integer is in the file.
So I need to do something like this. I need to read the string "aaaa" first, then I will read 1, then I'll read "bbbb", then 2 and so on.

Is there any way in which I can do the above. Something like readNextString() or readNextInteger().

I know I can use BufferedReader and read lines and do manipulation on each lines. But I am looking for something that we have in C++ like shown below

Code:

---

    int number;
    char name[10] ;
    ifstream in("test.txt");
    if (in.is_open())
    {
        in >> name; [I][COLOR="YellowGreen"]//gets "aaaa" here[/COLOR][/I]
        in >> number; [COLOR="YellowGreen"][I]//gets 1 here[/I][/COLOR]
        [I][COLOR="YellowGreen"]//and so on[/COLOR][/I]
    }

Take a look at the Scanner class

Oh... how could I forget Scanner. Thanks for reminding. :)
But, Scanner doesn't have a getString() method nah. So any way to do it?

Try using a BufferedReader and the String class.

Code:

---

File file = new File("path");
BufferedReader bReader = new BufferedReader(file);
String line = bReader.readLine();

---

And use the String class's methods to work with the String you read and grab certain values from it.

Perhaps the most useful methods for you would be substring() and indexOf().

Good luck!

@Solarsonic : As said in my first post, I already use BufferedReader. My purpose is to extract a string and an integer separately.

I'll put it in simple way here. In one fine I have just one line which is a string-integer pair. I have a String variable and int variable in my code. From the string-integer pair, I need to put the string value in String variable and the integer value in the int variable. The programmer has the information that the string-integer pair will be separated by space.

As already mentioned if you were using a Scanner, you could use nextInt() to get your number and next() to get a String token and nextLine() to get a String line, but you would need to take care to handle the end of line token. I'm not sure why you dismissed this suggestion out of hand. Otherwise you could grab your lines and split them via String's split method and iterate through the array of String/tokens that are returned.

Thanks Fubarable,
This is exactly what I need. I overlooked next() method. That is giving me the next string in the file.
