question: private int findSlashName ( byte [ ] d , String name ) { int i ; for ( i = 0 ; i < d . length ; i ++ ) { if ( d [ i ] == '/' ) { boolean found = true ; for ( int j = 0 ; j < name . length ( ) ; j ++ ) { if ( d [ i + j + 1 ] != name . charAt ( j ) ) { found = false ; break ; } } if ( found ) { return i ; } } } return - 1 ; }
target:  get the index into the byte array of a slashed name, like "/name".
