This simple code example will create the text file if it doesn't exist, and if it does, it will overwrite it: 

try {  
    FileWriter outFile = new FileWriter("c:/myfile.txt");  
    PrintWriter out = new PrintWriter(outFile);  
    // Also could be written as follows on one line  
    // Printwriter out = new PrintWriter(new FileWriter(filename));  
    // Write text to file  
    out.println("This is some text I wrote");  
    out.close();  
} catch (IOException e) {  
    e.printStackTrace();  
}

Hope it helps!

To create a new text file

FileOutputStream object=new FileOutputStream("a.txt",true);
object.write(byte[]);
object.close();

This will create a file if not available and if a file is already available it will append data to it.

Create a java.io.FileOutputStream to write it. To write text, you can create a PrintWriter around it.
