Ịghọta Klas Java, Isi ụzọ na njikwa loops na Java - Nkebi nke 3

N'ime ikpeazụ anyị post 'Ọrụ na koodu nhazi nke Java' anyị kwusiri ike na nkọwa nke ịrụ ọrụ Java, Java Source File, Java Class File, Class (Public/Private), Usoro, Nkwupụta, Mmemme Java mbụ gị, nchịkọta na ịgba ọsọ Java. Mmemme.

N'ebe a na usoro mmụta mmụta java a, anyị ga-aghọta ka klaasị java, usoro isi na njikwa loops si arụ ọrụ yana anyị ga-ahụkwa koodu ndị bụ isi site na iji klas Java na usoro isi na njikwa loops.

Ihe niile dị na Java bụ ihe na klaasị bụ ụkpụrụ nke ihe. A na-edobe koodu ọ bụla na Java n'okpuru ihe nkwado nke klaasị. Mgbe ị na-achịkọta mmemme Java ọ na-ewepụta faịlụ klaasị. Mgbe ị na-eme mmemme Java, ị naghị agba faịlụ mmemme n'ezie mana klaasị.

Mgbe ị na-eme mmemme na Java Virtual Machine (JVM), ọ na-ebu klas achọrọ wee gaa ozugbo na usoro () isi. Mmemme na-aga n'ihu ruo mgbe nkwado ndabere na mpaghara nke isi(). Mmemme ahụ na-amalite ime obere oge ka usoro isi() gachara. Otu klaasị ga-enwerịrị usoro() bụ isi. Ọ bụghị klaasị niile (Klas nkeonwe) chọrọ usoro isi().

Ụzọ isi() bụ ebe anwansi na-amalite. Ị nwere ike ịrịọ JVM ka o mee ihe ọ bụla n'ime usoro isi() site na nkwupụta/ntụziaka na loops.

Loop bụ ntụziaka ma ọ bụ ọtụtụ ntụziaka n'usoro nke na-aga n'ihu na-emegharị ruo mgbe ọnọdụ ahụ ruru. Loops bụ usoro ezi uche dị na ya nke asụsụ mmemme. A na-ejikarị usoro ezi uche eme ihe iji mee usoro, lelee ọnọdụ ahụ, mee usoro, lelee ọnọdụ ahụ, .... ruo mgbe achọrọ ọnọdụ.

Loops na Java

Enwere usoro loop atọ dị iche iche na Java.

ebe Loop na Java bụ njikwa njikwa nke a na-eji na-arụ ọrụ ugboro ugboro ruo oge ụfọdụ, dị ka akọwara na okwu boolean, ruo mgbe nsonaazụ nyocha ga-abụ eziokwu. Ọ bụrụ na nsonaazụ ederede boolean bụ ụgha, a ga-eleghara loop ahụ anya kpamkpam na-agaghị egbu ya ọbụlagodi otu oge.

Mmekọrịta nke oge loop:

while (boolean expression)
{

}

Ihe atụ nke mgbe Loop na Java:

public class While_loop

    {

An example of the for loop in Java

public class for_loop
{
    public static void main(String[] arge)
    {
        int A;
        for (A=100; A>=0; A=A-7)
        {

}

$ java for_loop 

Value of A = 100
Value of A = 93
Value of A = 86
Value of A = 79
Value of A = 72
Value of A = 65
Value of A = 58
Value of A = 51
Value of A = 44
Value of A = 37
Value of A = 30
Value of A = 23
Value of A = 16
Value of A = 9
Value of A = 2

Anatomi nke mmemme for_loop:

Okwu nkwụsịtụ ma gaa n'ihu maka loops na Java

Dị ka aha na-egosi na a na-eji okwu nkwụsịtụ kwụsịtụ akaghị ozugbo. A ghaghị iji mkpụrụokwu nkwụsịtụ mgbe niile n'ime akaghị ma ọ bụ nkwupụta mgbanwe. Ozugbo loop na-agbaji site na iji nkwụsịtụ; JVM na-amalite ime usoro ahịrị koodu na-esote na mpụga akaghị. Otu ihe atụ nke nkwụsịtụ loop na Java bụ:

public class break
{
    public static void main(String[] args)
    {
        int A = 100;
        while(A>0)
        {

        }
    }
}

$ java break 

The Value of A = 100
The Value of A = 90
The Value of A = 80
The Value of A = 70
The Value of A = 60
The Value of A = 50

Enwere ike iji mkpụrụokwu gaa n'ihu na loop ọ bụla na Java. Gaa n'ihu isiokwu rịọ loop ka ọ malie na nkwuputa ọzọ ozugbo. Otú ọ dị, a na-atụgharị ya n'ụzọ dị iche iche maka loop na mgbe/ime ... mgbe loop.

Gaa n'ihu na isiokwu maka wụli elu na nkwupụta mmelite ọzọ.

Ihe atụ nke ịga n'ihu maka loop:

public class continue_for_loop
