Is array a primitive data type in Java?

No, arrays are not primitive datatypes in Java. They are container objects which are created dynamically. All methods of class Object may be invoked on an array. They were considered as reference data types. Why array is non-primitive data type in C? Examples of non-primitive data structure are Array, Linked list, stack.

What is array in Java?

In our previous tutorials, we discussed that array is a collection of elements of the same data type in a contiguous fashion. You can have array declared with most of the primitive data types and use them in your program. Some arrays like character arrays or string arrays behave little differently than the rest of the data types.

How to initialize an array of primitive type?

As stated for an array of primitive type, an array of objects passed as argument is treated as a reference. You can use this characteristic of arrays to initialize the array. You can also indicate that the array is passed by reference by preceding its name with the refkeyword.

How to convert primitive array to string in JavaScript?

Convert the specified primitive array to a IntStream using Arrays.stream () or IntStream.of () method. Convert each element of the stream to a string using IntStream.mapToObj () method. Return a string array containing elements of this stream using Stream.toArray ().
