In Java, there are two simple waysto take array input from the user. You may utilize loopsand the “Scanner class” or “BufferedReader and InputStreamReader class” to accept an array input from the user. Let’s cover both these methods in detail with examples.
The Scanner classis part of the ‘java.util‘ package and is used to take input from the user. We can use the Scanner class with loops to take input for individual array elements (To use this technique we must know the length of the array). Below is the implementation of using Scanner class and loops to take array input in Java:
We can use the BufferedReaderobjectto read user input in Java and use the IOException Classto handle exceptionsin input. In the program below we use the BufferedReader objectto read user input and manage the input classes such that even with the wrong input type the error is not thrown.
In conclusion, array input is important for building user-friendly Java applications. While Java lacks a direct array input method, we’ve explored two effective approaches in this tutorial.

A String Array can be declared as follows: String [] stringArray1 //Declaration of the String Array without specifying the size. String [] stringArray2 = new String [2]; //Declarartion by specifying the size. Another way of declaring the Array is String strArray [], but the above-specified methods are more efficient and recommended. Initialization:
