Is there another way to print the code?

That's quite an old way. There are more modern ways such as https://docs.oracle.com/en/java/javase/24/docs/api/java.base/java/lang/String.html#join(java.lang.CharSequence,java.lang.Iterable) and even that's not exactly new.

Though for printing lines I wouldn't use String.join - for large arrays this would create a huge String first, and is just extra work.
Once you've encountered Streams and Lambdas or Method References, you can do this...
// get a Stream over the array
Arrays.stream(strings)
// for each element in the Stream, pass it to System.out.println
.forEach(System.out::println);
Which can also be written with a lambda...
// get a Stream over the array
Arrays.stream(strings)
// for each element in the Stream, pass it to System.out.println
.forEach(string -> System.out.println(string));
But you can still use a for-loop, and an enhanced for-loop is pretty simple...
for (String string : strings) {
System.out.println(string);
}
This last is actually translated to almost exactly the loop proposed by zarakshR...
Something like...
for (int $index = 0, $length = strings.length; $index < $length; $index++) {
String string = strings[$index];
System.out.println(string);
}

I suspect you are new to programming, in which case I would recommend learning what a loop is and how to use it here; you can try to understand the other solutions posted here once you are a little more comfortable with Java and programming in general

There are a lot of ways beyond basic for loops.

use this loop
for(String str: aCoolString){
System.out.println(str);
}

yeah, but I think the guy is new to programming so he's probably better off starting with loops

Usually they would teach a while loop first.
int i = 0;
while (i < aCoolString.length) {
String string = aCoolString[i];
System.out.println(string);
i++;
}
The simple for-loop is just a rearrangement of that
for (int i = 0; i < aCoolString.length; i++) {
String string = aCoolString[i];
System.out.println(string);
}
And the enhanced-for loop does some of these steps for you
for (String string : aCoolString.) {
System.out.println(string);
}
The MOOC will teach this gradually.
