- // Let's change the name of our class as it will now be
- // more generic. Same rule applies about the implied
- // "extends" ("extends Object" is implied).
- //
- class EchoString {
- public static void main( String args[] )
- {
- //
- // If only one arg comes in we want to print it without
- // a trailing blank so we print this solitary arg
- // if one actually exists. This is a bit of overkill,
- // but examples shouldn't be too far off the mark.
- //
- if ( args.length > 0 )
- System.out.print( args[0] );
-
- //
- // I only need i in my for loop so I declare it
- // within the parens (similar to C++). args is
- // an array so, by definition, its internal variable,
- // length, contains its length (which equates to
- // the number of arguments. No more argc!).
- //
- for ( int i = 1; i < args.length; i++ )
- {
- System.out.print( " " ); // Separate the arguments
- System.out.print( args[i] );
- }
-
- //
- // We do this because System.out will only flush on a newline
- // (don't believe me? Look in Java/src/java/io/PrintStream.java.
- // the PrintStream autoflush variable is set to false
- // when the first constructor calls the second with an
- // autoflush argument of false).
- //
- System.out.println();
