Is array a primitive type or object in java?

Arrays are objects in java. Everything you create using new operator is an object in java. .

What is the class of the array?

Every array type has corresponding classes with it.

Below table summarizes the arrays and the class associated with them.

Primitive Array	Class
boolean[]	class [Z
byte[]	class [B
short[]	class [S
int[]	class [I
long[]	class [J
float[]	class [F
double[]	class [D
char[]	class [C
Object[]	class [Ljava.lang.Object;
Employee[]	class [Lcom.sample.test.Test$Employee;

Test.java

package com.sample.test;

public class Test {
 
 private static class Employee{
  
 }

 public static void main(String args[]) {
  System.out.println("Array Type\tClass Name");
  System.out.println("boolean[]\t" + new boolean[0].getClass());
  System.out.println("byte[]\t" + new byte[0].getClass());
  System.out.println("short[]\t" + new short[0].getClass());
  System.out.println("int[]\t" + new int[0].getClass());
  System.out.println("long[]\t" + new long[0].getClass());
  System.out.println("float[]\t" + new float[0].getClass());
  System.out.println("double[]\t" + new double[0].getClass());
  System.out.println("char[]\t" + new char[0].getClass());
  System.out.println("Object[]\t" + new Object[0].getClass());
  System.out.println("Employee[]\t" + new Employee[0].getClass());
 }
}

Output

Array Type Class Name
boolean[] class [Z
byte[] class [B
short[] class [S
int[] class [I
long[] class [J
float[] class [F
double[] class [D
char[] class [C
Object[] class [Ljava.lang.Object;
Employee[] class [Lcom.sample.test.Test$Employee;

What is class [Z in above output?
[Z is the class name here. Single [ represents one dimensional array. [[ represent two-dimensional array.

For example, below program display the classes of two-dimensional array.

Test.java

package com.sample.test;

public class Test {

 private static class Employee {

 }

 public static void main(String args[]) {
  System.out.println("Array Type\tClass Name");
  System.out.println("boolean[][]\t" + new boolean[0][0].getClass());
  System.out.println("byte[][]\t" + new byte[0][0].getClass());
  System.out.println("short[][]\t" + new short[0][0].getClass());
  System.out.println("int[][]\t" + new int[0][0].getClass());
  System.out.println("long[][]\t" + new long[0][0].getClass());
  System.out.println("float[][]\t" + new float[0][0].getClass());
  System.out.println("double[][]\t" + new double[0][0].getClass());
  System.out.println("char[][]\t" + new char[0][0].getClass());
  System.out.println("Object[][]\t" + new Object[0][0].getClass());
  System.out.println("Employee[][]\t" + new Employee[0][0].getClass());
 }
}

Output

Array Type Class Name
boolean[][] class [[Z
byte[][] class [[B
short[][] class [[S
int[][] class [[I
long[][] class [[J
float[][] class [[F
double[][] class [[D
char[][] class [[C
Object[][] class [[Ljava.lang.Object;
Employee[][] class [[Lcom.sample.test.Test$Employee;
