System.out.println("What is the name of your output file? ");
String fileName = in.nextLine();//get output file name
File file = new File(fileName);//File object with fileName as input
//Create the file by method file.createNewFile()
if (file.createNewFile())
{
System.out.println("File is created!");
} else {
System.out.println("File already exists.");
}
//FileWriter object with user file name given as input
FileWriter writer = new FileWriter(file);
System.out.println("Enter text to write to a file : ");
String line;//variable to store line content
do {
line=in.nextLine();//get line content from user
writer.write(line+"\n"); //write content to file by adding new line(\n) character
}while(!line.equals("STOP!"));//repeat a loop until user enters "STOP!" line
writer.close();//close the file object
}
