Answer by PrivateName for In detail, how does the 'for each' loop work in Java?

A foreach loop syntax is:

for (type obj:array) {...}

Example:

String[] s = {"Java", "Coffe", "Is", "Cool"};for (String str:s /*s is the array*/) {    System.out.println(str);}

Output:

JavaCoffeIsCool

WARNING: You can access array elements with the foreach loop, but you can NOT initialize them. Use the original for loop for that.

WARNING: You must match the type of the array with the other object.

for (double b:s) // Invalid-double is not String

If you want to edit elements, use the original for loop like this:

for (int i = 0; i < s.length-1 /*-1 because of the 0 index */; i++) {    if (i==1) //1 because once again I say the 0 index        s[i]="2 is cool";    else        s[i] = "hello";}

Now if we dump s to the console, we get:

hello2 is coolhellohello
