public class P3 { public static void main( String args[] ) { String[] words = { "alpha", "bravo", "charlie", "delta", "echo" }; String[] blanks ={ "blank", "blank", "blank", "blank", "blank" }; int j=0; for (int i=words.length-1 ; i>=0 ; --i) mystery( words[i], blanks[j++] ); for (int i=0 ; i< blanks.length ; ++i ) System.out.print( blanks[i] + " "); } private static void mystery( String s1, String s2 ) { String tmp = s1; s1 = s2; s2 = tmp; } } 

Solution :

blank blank blank blank blank 

Why does it only print out just blank also I was told that it was becasue it was out of scope but why is it out of scope.
