Subsequently, question is, how do you declare a two dimensional array in Java? Create Two dimensional Array in Java In order to create a two dimensional array in Java, we have to use the New operator as we shown below: Data_Type Array_Name = new int[Row_Size][Column_Size]; If we observe the above two dimensional array code snippet, Row_Size: Number of Row elements an array can store.
