Thread: placing comma between strings in a line

I read a file containing declaration statements like int a b float a1 b1 in separate lines.
now i should copy these read line into another file by separating variables with comma as we declare in programs.Am able to read from a file and copy to another file.but how to separate variables with comma?

Split the line and add a comma after each token.

Show us your code and the data, so we can advise you better.

public class first
{
public static void main(String args[])
{
String line,line1;
 String array[]=new String[20];
BufferedWriter bw = new BufferedWriter(new FileWriter("F:\\prog1\\file1.txt",true);
 StringBuffer  sb = new StringBuffer();
Scanner scan=new Scanner(new File("F:\\prog\\file.txt"));
while (scan.hasNext())
{
line=scan.next();
line1=line.toLowerCase();
array=line1.trim().spilt("\\s+"); 
}
sb.append(array[0]).append(" ");
for(int i=1;i<array.length;i++)
 {
 
 sb.append(array[i]).append(",");
}
 
				bw.write(sb.toString());
				bw.flush();
				bw.close();
}
}

when i write the above code i can insert comma between variables but i should end the line with semicoln instead i am ending with comma.
