java. Lang. class and equal

According to the Javadoc of the class

But when I ran down there

int[] intArray = { 1,2 };
out.println(intArray.getClass().hashCode());
int[] int2Array = { 1,2 };
out.println(int2Array.getClass().hashCode());

out.println(intArray.equals(int2Array));

I get the following output

1641745
1641745
false

I want to know why equals returns false, even if both arrays are of type int and have the same dimension

Solution

This is because you called equals () on array instances instead of their class objects Try:

out.println(intArray.getClass().equals(int2Array.getClass())); //prints true

You can also write:

out.println(int[].class.equals(int[].class)); //prints true thankfully

In addition, matching hash codes do not necessarily represent equality, although this is not important
