For loop in the form of : “for (A b : c)” in Java

Question

This is the first time that I\'ve seen this kind of syntax :

// class Node
public class Node { 

...
...

}

public class Otherclass { ... }

Otherclass gra         


        

Answer 1

That is a for-each loop (also called an enhanced-for.)

for (type var : arr) { //could be used to iterate over array/Collections class
    body-of-loop
}

The basic for loop was extended in Java 5 to make iteration over arrays and other collections more convenient. This newer for statement is called the enhanced for or for-each
