question: protected boolean test ( String val1 , String val2 , StringBuffer buf ) { boolean ret = false ; switch ( op ) { case 1 : ret = val1 . equals ( val2 ) ; break ; case 2 : ret = ! val1 . equals ( val2 ) ; break ; } if ( buf != null ) { String operation = null ; switch ( op ) { case 1 : operation = ( ret + "=" + val1 + "==" + val2 ) ; break ; case 2 : operation = ( ret + "=" + val1 + "!=" + val2 ) ; break ; } buf . append ( "\n   " + toString ( ) + ":" + operation ) ; } return ret ; }
target:  The basic test for the operator, returning val1 op val2.
