Printing the Contents of an Array

If you try to use System.out.println to output a String[] you won't see the contents of the array. Instead you will see something like [Ljava.lang.String;@1c655221.

String[] shout = { "fus", "ro", "dah" };
// [Ljava.lang.String;@5a07e868
System.out.println(shout);

A similar thing will happen with int[], boolean[], and double[].¹

int[] nums = { 11, 11, 11 };
// [I@5a07e868
System.out.println(nums);

boolean[] bools = { true, false };
// [Z@5a07e868
System.out.println(bools);

double[] doubles = { 1.1, 1.1, 1.1 };
// [D@5a07e868
System.out.println(bools);

The only kind of array which will include its contents when printed is a char[]. It will be printed as if it were a String.

char[] continent = { 'T', 'a', 'm', 'r', 'i', 'e', 'l' };
// Tamriel
System.out.println(continent);

If you want to actually see the contents of an array, you should use a loop.²

String[] factions = { "empire", "stormcloaks", "dragons" };

int index = 0;
while (index < factions.length) {
    System.out.println(factions[index])
    index++
}
