Question

Below is an example program from some notes on how to use the for loop in Java. I don’t understand how the line element:arrayname works. Can someone briefly explain it, or provide a link to a page that does?

public class foreachloop {
    public static void main (String [] args) {
        int [] smallprimes= new int [3]; 
        smallprimes[0]=2;
        smallprimes[1]=3;
        smallprimes[2]=5;

        // for each loop
        for (int element:smallprimes) {
            System.out.println("smallprimes="+element);   
        }
    }
}

Answer 1

It’s another way to say: for each element in the array smallprimes.

It’s equivalent to

for (int i=0; i< smallprimes.length; i++)
{
     int element=smallprimes[i];
     System.out.println("smallprimes="+element);   
}
