use Of printf()
Dear friends,
in one of the many programs i found that they are using printf in System.out.printf();
Is that possible to use printf() in java, how?, when should we use it?
The code is :
publicclass FileDemonstration
{
// display information about file user specifies
publicvoid analyzePath( String path )
{
// create File object based on user input
File name =new File( path );
if ( name.exists() )// if name exists, output information about it
{
// display file (or directory) information
System.out.printf(
"%s%s\n%s\n%s\n%s\n%s%s\n%s%s\n%s%s\n%s%s\n%s%s",
name.getName()," exists",
( name.isFile() ?"is a file" :"is not a file" ),
( name.isDirectory() ?"is a directory" :
"is not a directory" ),
( name.isAbsolute() ?"is absolute path" :
"is not absolute path" ),"Last modified: ",
name.lastModified(),"Length: ", name.length(),
"Path: ", name.getPath(),"Absolute path: ",
name.getAbsolutePath(),"Parent: ", name.getParent() );
if ( name.isDirectory() )// output directory listing
{
String directory[] = name.list();
System.out.println("\n\nDirectory contents:\n" );
for ( String directoryName : directory )
System.out.printf("%s\n", directoryName );
}// end else
}// end outer if
else// not file or directory, output error message
{
System.out.printf("%s %s", path,"does not exist." );
}// end else
}// end method analyzePath
}// end class FileDemonstration
Thank you
