Syntax: It considers an array as a typical object and returns default string, i.e., a ‘[‘ representing an array, followed by a character representing the primitive data type of array followed by an Identity Hex Code [See this for details] We can print one-dimensional arrays using this method. Iterate over String Array using Advanced For Loop. Statement 2 defines the condition for the loop to run (i must be less than 5). Step 2: Create a character array of the same length as of string.

(If you haven't used it before, when using a JList, it can be very helpful to know the length of the longest String in your Java String array.) Next, we are using For Loop to iterate each element in this array, and print those array elements. Loop method: The first thing that comes to mind is to write a for loop from i = 0 to n, and print each element by arr[i].
