Re: equals, hashcode, permission

[Vladimir Bobes Tuzinsky]

to suvisi s tym, ze a aj b ukazuje na ten isty objekt. Je to vdaka String poolu. Ale to je opat jedna zo zakladnych veci, ktore sa daju nastudovat v beznej literature. Mam pocit, ze este jeden den pride na konferenciu tolko spamu ako dnes, tak sa z nej odhlasim... :(

Jeste me trochu zarazi to equals...

Protoze jsem zkousel napsat si program:

 

String a =

"TEXT";

String b =

"TEXT";

if ( a == b )

System.

out.println ( "a and b are the same." );

 

A v pohode to proslo a funguvalo, takze jsem z toho trosku paf ;-)

Jasne, ale i v tom druhem pripade musi byt take equals, protoze getActions je taky jenom String,

 

Nic jineho uz tam krome equals a nullpointerexception neni?

Je tam jeste nejaka chyba?

Uz iba ta klasicka o porovnavani Stringov. Takze namiesto:

if ( ( cp.getName == this.getName () ) && cp.getActions () == this.getActions ()  )

           
ma byt

if ( cp.getName().equals(this.getName()) && cp.getActions () == this.getActions ()  )

            return true;
