foreach in Java, used to iterate through an array

Here for is a foreach in Java,   used to iterate over the array.
for (int i:d) is the data that iterates through the array d of the  int type every time you access it, put it in the int type I.
and for (int i=0;i<d.length (); i++) are the same, but there are more available cases of foreach.

public class E1 {
public static void Main (string[] args) {
Int[]d=new int[] {1,2,3,4,64,1234,3124,657,22};
System.out.println ("d.length=" +d.length);
for (int i:d) {
                    System.out.println (i);
                 }
