Problems using Scanner
Hi,
I'm having problems with a small piece I've code I've written, which implements Scanner, not behaving as predicted.
What I would like it to do is read in a line of text in an expected format, print the line then print each number in the line on a new line followed by the string, before moving on to the next line in the txt file. For example if the input is:
1 0 5 6 "Frame",
2 0 5 6 "Exposure",
...
I would like the code to out put:
1 0 5 6 "Frame",
1
0
5
6
"Frame"
2 0 5 6 "Exposure",
2
0
5
6
"Exposure"
etc.
Instead what I get is:
1 0 5 6 "Frame",
2 0 5 6 "Exposure",
...
1
0
5
6
"Frame"
And that's it. The code only breaks up the lines after its read them all in and even then it only processes the first line. Here's the code:
import java.io.*;
import java.util.Scanner;
publicclass scanText{
publicstaticvoid main(String[] args)throws IOException{
Scanner fs =null;
Scanner ts =null;
String token =null;
String msg =null;
int num;
try{
fs =new Scanner(new BufferedReader(new FileReader("testText.txt")));
fs.useDelimiter("\\r");
while (fs.hasNext()){
token = fs.next();
System.out.println(token);
ts =new Scanner(token);
ts.useDelimiter("\\s*");
while (ts.hasNextInt()){
num = ts.nextInt();
System.out.println(num);
}
if (ts.hasNext()){
ts.useDelimiter(",");
msg = ts.next();
System.out.println(msg);
}
}
}finally{
if (fs !=null){
fs.close();
}
if (ts !=null){
ts.close();
}
}
}
}
I'm sure I'm missing something simple in my implementation. Could a fresh eye please help me out?
