Java döngü için Programın bir bölümünü birkaç kez yinelemek için kullanılır. Yineleme sayısı ise sabit for döngüsünün kullanılması tavsiye edilir.

Java'da üç tip for döngüsü vardır.

• Döngü için Basit
• Her biri için veya Döngü için Geliştirilmiş
• Döngü için etiketlendi

Döngü için Java Basit

Basit bir for döngüsü şununla aynıdır: C / C++ . Başlatabiliriz değişken , durumu kontrol edin ve değeri artırın/azaltın. Dört bölümden oluşur:

Başlatma: Döngü başladığında bir kez çalıştırılan başlangıç ​​koşuludur. Burada değişkeni başlatabiliriz veya önceden başlatılmış bir değişkeni kullanabiliriz. İsteğe bağlı bir durumdur.Durum: Döngünün durumunu test etmek için her seferinde çalıştırılan ikinci koşuldur. Koşul yanlış olana kadar yürütmeye devam eder. Boole değerini doğru veya yanlış olarak döndürmesi gerekir. İsteğe bağlı bir durumdur.Arttırma/Azaltma: Değişken değerini artırır veya azaltır. İsteğe bağlı bir durumdur.İfade: Döngünün ifadesi, ikinci koşul yanlış olana kadar her seferinde yürütülür.

Sözdizimi:

 for(initialization; condition; increment/decrement){ //statement or code to be executed }

Her Döngü için Java

For-each döngüsü Java'da dizi veya koleksiyonda geçiş yapmak için kullanılır. Kullanımı basit for döngüsünden daha kolaydır çünkü değeri artırmamıza ve alt simge gösterimini kullanmamıza gerek yoktur.

İndeks bazında değil, öğeler bazında çalışır. Tanımlanan değişkendeki elemanları tek tek döndürür.

Sözdizimi:

 for(data_type variable : array_name){ //code to be executed }

Döngü için Java Mastarı

İki noktalı virgül kullanırsanız ;; for döngüsünde for döngüsünde mastar olacaktır.

Sözdizimi:

 for(;;){ //code to be executed } 

Örnek:

Örnek.java için

 //Java program to demonstrate the use of infinite for loop //which prints an statement public class ForExample { public static void main(String[] args) { //Using no condition in for loop for(;;){ System.out.println('infinitive loop'); } } } 

Çıktı:

 infinitive loop infinitive loop infinitive loop infinitive loop infinitive loop ctrl+c 

Şimdi programdan çıkmak için ctrl+c tuşlarına basmanız gerekiyor.
