Write to file

i use below code to write a character to a file, the old contents cleared but nothing is written :
File edgesFile = new File(netFile);
FileOutputStream inFile = null;
try
{
inFile = new FileOutputStream(edgesFile);
}
catch(FileNotFoundException e)
{
e.printStackTrace(System.err);
System.exit(1);
}
FileChannel inChannel = inFile.getChannel();
ByteBuffer buf = ByteBuffer.allocate(48);
buf.putChar('q');
try
{
inChannel.write(buf);
inChannel.force(true);
inChannel.close();
}
catch(IOException e)
{
e.printStackTrace(System.err);
}
and another thing how can i write a string array to a file that any element be in one line?

It depends on how you will save them in a file....

You may try to use Formatter for saving files in format, and also the FileWriter....

Those classes are safe to implement.

Code:

---

void WriteFile throws Exception(){
    FileWriter fw = new FileWriter(netFile);
    fw.append('q');
    fw.close();
}

---

Code:

---

void WriteFile throws Exception(){
    Formatter write = new Formatter(netFile);
    write.format("%c",'q');
    write.close();
}
