Java za petlju koristi se za ponavljanje dijela programa nekoliko puta. Ako je broj ponavljanja fiksni , preporuča se koristiti for petlju.

U Javi postoje tri vrste for petlji.

css podebljano

• Jednostavno za petlju
• Za svakoga ili Enhanced for Loop
• Označeno za petlju

Java Simple for Loop

Jednostavna for petlja je ista kao C / C++ . Možemo inicijalizirati varijabla , provjerite uvjet i vrijednost povećanja/smanjenja. Sastoji se od četiri dijela:

Inicijalizacija: To je početni uvjet koji se izvršava jednom prilikom pokretanja petlje. Ovdje možemo inicijalizirati varijablu ili možemo koristiti već inicijaliziranu varijablu. To je izborni uvjet.Stanje: To je drugi uvjet koji se izvršava svaki put za testiranje uvjeta petlje. Nastavlja s izvođenjem sve dok uvjet nije lažan. Mora vratiti Booleovu vrijednost true ili false. To je izborni uvjet.Povećaj/Smanji: Povećava ili smanjuje vrijednost varijable. To je izborni uvjet.Izjava: Izjava petlje se izvršava svaki put dok drugi uvjet nije lažan.

Java za svaku petlju

Petlja for-each koristi se za prelaženje niza ili zbirke u Javi. Lakše ju je koristiti od jednostavne for petlje jer ne trebamo povećavati vrijednost i koristiti indeksni zapis.

Radi na temelju elemenata, a ne indeksa. Vraća element jedan po jedan u definiranoj varijabli.

Java infinitiv za petlju

Ako koristite dvije točke i zareze ;; u for petlji, to će biti infinitivna for petlja.

Sintaksa:

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

Primjer:

Na primjer.java

 //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'); } } } 

Izlaz:

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

Sada morate pritisnuti ctrl+c za izlaz iz programa.
