Niulize chochote kuhusu java na xml

[Maserati]

Nilijua HKL mtajipitisha hapa, kuomba maji ya kunywa..!

Still there in my throat?? Soma kichwa cha habari,kasema aulizwe chochote kuhusu java. Haya get out of my shoes..

bahati mbaya kiswahili hapa kinagota ngoja nikupe vitu namna hii.
java is an object oriented programming language with a built-in Application programming interface(API) that can handle graphical user interface (GUI) used to create applications or applets .

mfano

maserati umeclick/umebofya icon ya whatsapp hiyo ni GUI ili ifunguke mpaka uone ndani kuna message n.k kuna kitu inaitwa API ndio inayo itikia na kukufungulia dunia kuwa unachotaka au sio.

mfano mwingine ni tuchukulie umegusa ngozi ya kiumbe kilicho hai kitahisi umekigusa na kitashituka/respond maana yake umegusa GUI na Sasa API anarespond kupitia GUI

au tuseme GUI bila API ni sawa na MWANADAMU BILA UHAI

Jibu kimalkia hicho hicho

unaelewa uzi unasemaje jamani huu uzi wa java na xml(extended markup language) sio html na javascript

sio java wala xml ila kumbe ni kitu gani mkuuu?

hahaha we jamaa mchokozi sana

Mimi nimesha kula kozi ya bb code sasa naamia kwenye java

 

[Upepo wa Pesa]

mi sio mwingi sanaaaa ! lakini niulize chochote kuhusu lugha hizi uone kama niko vizuri au hapana


zingatia:

HAPA TUNAZUNGUMZIA JAVA NA XML(EXTENDED MARKUP LANGUAGE)

SIO

JAVASCRIPT NA HTML

Je ni kwanini java haisapoti multiple inheritance bila interfaces?

Ni mazingira gani unatakiwa kutumia abstract classes na methods?

 

[Tecno_one]

Ni editor IPI... Ambayo ni nzuri kwakufanya java

 

[Mtangoo]

1. Ukilinganisha na apps za C++ kwa nini Java sio rafiki unapotaka kutumia Pluggable architecture

2. Unapokuwa na multiple programs zilizotengenezwa kwa different incompatible JREs unafanyaje ili zote zifanye kazi?

Anz Kupasha na hayo kwanza...!

The top ones ni eclipse, netbeans na IntelJ

IntelJ is the best!!

Kwa kifupi kama unamiliki smartphone inayotumia android jua java imetumika kutengeneza applications unazo download play store!

sio asilimia zote kua kila application iliyopo kwenye play store au inayoinstalliwa kwenye android imetengenezwa na Java programming lang.

Nilitegemea hii comment...

Najua kuna c++, c#, javascript, and now we have kotlin ila mwisho wa siku java is the dominant one!

karibu

Thanks naomba introduction ya java kidogo nipate mwanga

Haisupport multiple inhertence mpaka uwepo wa interface kwasababu class inakuwa na uwezo wa kuinhert interface nyingi zikiwa na methods zinazofanana/kwa lugha nzuri ni kwamba interface zinakuwa na methods ambazo uwa public/abstract .kwa maana hii method ndani ya interface haiwezi kujifanyia tu implementation pekeyake so tunaitaji interface kwa ajili ya multiple inhertence.


pia naitaji abstract classes ninapotaka kufanya classes zinazoendana zichukuriane code na pia abstract method wakati nataka subclasses ziimplement kila method kwa namna yake.


AU VIPI MKUU

Nakushauri tumia ide(integrated development environment ) hii ina source code editor, debuggers, compiler, interpreter, build automation

Mfano wa IDE ni eclipse au netbeans n.k.


Sio Editor maana hazina feature kama IDE mfano wa editor ni notepad++,bracket,komodo n.k

Class ina inherit interface?

Kwenye abstract classes tuna kitu kinaitwa implementation?

Nimesema mi si
mwingi sana labda unisaidie kwenye hayo makosa

 

[TEAM 666]

Kuna umuhimu gani wakuijua Java?

Kiuhalisia huwezi uka inherit au uka extend interface kwa kutumia class!

Class ina implement interface, class can not extend/inherit interface!

Cheki hii code

interface persons{
    void name();
    void surname();
}
interface activities{
    void nameOfActivities();
}
class Group implements persons,activities{
    @Override
    public void name() {
        System.out.println("My name is ABC");
    }

    @Override
    public void surname() {
        System.out.println("my surname is XYZ");
    }

    @Override
    public void nameOfActivities() {
        System.out.println("My activities are ....");
    }
}

Ukisema nitoe implement alafu nitumie inheritance ya class na interface utapata error maana hakuna inheritance kati ya class na interface bali kuna inheritance ya class na class au interface na interface!!

Likewise kwenye abstract haiwezi kuimplement abstract class, ina inherit au ina extend abstract class!!

At the end of the day you can not instantiate abstract class but you can instantiate concrete class!!!
