eclipse - Why do hashCode & equal need non-static fields to be generated? -

-

i curious error while testing out eclipses' functionality:

enter image description here

i tried use command "generate hashcode & equals", because class has static methods rejected it. how work(i.e. hashcode/equals needing non-static methods ? )?

thank you

hashcode , equals methods belonging concrete object , need members belonging object compute meaningful value.

eg. if want compare 2 instances of same class, comparing "computed values" through equals and/or hashcode methods.

static methods , members belong class , not concrete instance uniquely.

i have google question , find answer in day. know, data design many many table have list column,and mark pk , fk. why er-diagram have find this? data design process of designing database. main output of data design detailed logical data model of database. some people data design includes of needed logical , physical design choices , physical storage parameters needed generate design in data definition language. technically, database analysis, database analysts (dbas) trained do. while person can both data design , database analysis, these 2 different tasks. data design models data. database analysis takes model , applies 1 or more database engines (relational, hierarchical, nosql). a logical data model 1 of main outputs of data design. data model represented entity relationship diagram, or er diagram.
