question: compares two objects for equality , where either one or both objects may be null . objectutils.equals null , null = true objectutils.equals null , '' '' = false objectutils.equals '' '' , null = false objectutils.equals '' '' , '' '' = true objectutils.equals boolean.true , null = false objectutils.equals boolean.true , `` true '' = false objectutils.equals boolean.true , boolean.true = true objectutils.equals boolean.true , boolean.false = false concode_field_sep Null NULL concode_elem_sep long serialVersionUID concode_field_sep Object defaultIfNull concode_elem_sep Object readResolve concode_elem_sep int hashCode concode_elem_sep String identityToString concode_elem_sep void identityToString concode_elem_sep String toString concode_elem_sep String toString
target: boolean function ( Object arg0 , Object arg1 ) { if ( arg0 == arg1 ) { return true ; } if ( ( arg0 == null ) || ( arg1 == null ) ) { return false ; } return arg0 . equals ( arg1 ) ; }
