Two objects are strictly equal if they refer to the same Object. Null and Undefined types are == (but not ===). [I.e. Null==Undefined (but not Null===Undefined)]The 3 equal signs mean "equality without type coercion". Using the triple equals, the values must be equal in type as...
This tutorial explains the difference between size and length in Java. We have also listed some sample codes to help you understand the topic. Java has asize()method and alengthproperty. Beginners may think that they are interchangeable and perform the same task because they sound somewhat the ...
It's a good practice to make Value Objects immutable. The change in values occurs only by creating a new object and not by updating values in the old object itself. This helps in understanding the implicit contract that two Value Objects created equal should remain equal. Let's defineEmployee...
Just like double equal operator === also used to compare two values on left and right. This will also return true or false based on comparison. Triple equal operator is also common used in if else conditions, while loops and some other places in code. So the difference between == and =...
Now for structural equality, we use the==symbol that evaluates if both values are the same (or equal). This is usually achieved by implementingequals()method in Java. So, using the sameIntegersexample, we just need to doa == b, and in this case, it will returntrue, since both variabl...

In contrast to the primitive type int, Integer is a full-blown Java class. This creates a long list of difference, such as: The Integer class is an Object while an int is a primitive type. The Integer is compared with.equalswhile the int uses two equal signs,==. ...
Assert.assertTrue(a.equals(b)) If a and b are same, we wonât find any differences in these 2 assertions but when there is a failure, or these variables are not same we can notice the differences in error messages. assertEquals()throws clear message about exception as shown belo...
