In the Java code below what are the errors? File fileDir = new File("C:\test");
File file = new File("C://test//test. txt");
if (fileDir. exists()) { fileDir. mkdir();
System. out. println("The directory does not exist.\nCreating directory...");
} else
{
System. out. printf("The directory does exist at this location: \n%s\n", fileDir. getAbsolutePath());
}
if (file. exists()) { System. out. println("The file does not exist.\nCreating file...");

file. createFile(); System. out. printf("The file now exists and is located here:\n%s\n", file. getAbsolutePath());

}
else { System. out. printf("The file already exists and is located here:\n%s\n", file. getAbsolutePath());
}
PrintWriter output = new PrintWriter(fileName); double amount = 456.73;
for (int i = 1; i <= 10; i++) { output. printf("Account %d:\t $%.2f" + System. getProperty("line. separator"), i, amount += 23.45);

}
output. close(); try (Scanner input = new Scanner(file)) { System. out. println("The contents of the file are listed below:");

while (input. hasNext()) { String line = input. nextLine(); System. out. println(line); }

} input. close();

to change your username, you must:

1) make sure what the username you want to change to is allowed in this community

2) contact a administrator (for example, jaysl)
