main

public static void main(String... args)

The main method for the formatter, with some number of file names to format. We process them in parallel, but we must be careful; if multiple file names refer to the same file (which is hard to determine), we must serialize their updates.

Parameters:

args - the command-line arguments

main

static int main(InputStream in,
 PrintStream out,
 PrintStream err,
 String... args)

Package-private main entry point used by the Tool implementation in the same package as this Main class.
