Java ni lugha ya programu. Iliundwa na James Gosling na ilianzishwa tarehe 23 Mei 1995. Iliundwa ili kuumba programu kwa Android. Leo tunatumia Java SE 13. Ilivutwa na C++.

Historia[hariri | hariri chanzo]

Ilianzishwa mwaka wa 1995 nchini Marekani. James Gosling, Mike Sheridan, na Patrick Naughton walianza kufanya kazi kuhusu Java mwaka wa 1991. Mwaka wa 1996 Sun Microsystems ilichapa Java 1.0.

Falsafa[hariri | hariri chanzo]

Namna ya Java ni ile inaozingatiwa kuhusu kipengee na namna nyingi.

Sintaksia[hariri | hariri chanzo]

Sintaksia ya Java ni ngumu sana; inafananishwa na lugha za programu nyingine kama JavaScript, Python au Ruby. Ilivutwa na sintaksia ya C++, lugha ya programu nyingine.

Mifano ya Java[hariri | hariri chanzo]

Programu kwa kuchapa « Jambo ulimwengu !».

public class JamboUlimwengu {
    public static void main(String[] args) {
        System.out.println("Jambo ulimwengu !");
    }
}

Programu kwa kutafuta thamani katika jedwali.

class Mfano2 {
    public static void main(String[] args) {
        int[] table = {12, -5, 7, 8, -6, 6, 4, 78, 2};
        byte elt = 4;
        short i;
        for (i = 0; i < 8; i++) {
            if (elt == table[i]) {
                break;
            }
        }
        afficher(i, elt);
    }

    static void afficher(int rang, long val) {
        if (rang == 8) {
            System.out.println("thamani : " + val + " haitafutwi.");
        } else {
            System.out.println("thamani : " + val + " thamani anatafutwa in rank :" + rang);
        }
    }
}
