During your IT interview, you may be asked about the XOR operator in Java. Let us tell you the main facts about the XOR Java operator so that you can provide a complete answer on your job meeting. Take a look!
Does Java have an XOR operator?
This is the first IT interview question about XOR operators you should expect to get. The answer is a definite yes. Java does have an XOR operator and its representation in the programming language is the caret character (?^?).
The Main Facts about the Java XOR Operator
The main aim of the XOR operator in Java is comparing instances. The Java XOR feature will compare two instances and return one of the following values:
- If the two numbers or instances that are compared are identical, the XOR operator will return a 0, which means FALSE.
- If the two numbers or instances that are compared are different, then the XOR operator will return a 1, which means TRUE.
To get a better idea of how the XOR operator in Java works, we have created a table with several examples. In the first two columns of our tables (A and B), we have included the numbers or instances that will be compared using the XOR Java operator. In the third column (Return), we have included the return values of the Java XOR operator. In the fourth column (Return Meaning), we have included the meaning of the return values provided by this Java feature. Take a look!
|1||0/ FALSE||The numbers are identical.|
The numbers are identical.
|0||1/ TRUE||The numbers are different.|
The numbers are different.
How to Write an XOR function in Java
During your IT interview, you may be asked to provide a complete example of the Java XOR operator. It is very important that you know how to write this function in so that you make a good impression to the interviewers.
Writing an XOR function is very easy. We will provide you with an example, so that you know exactly what to say during your interview. Take a look at our XOR example!
For our XOR example, we are going to compare two entities named X and Y. To do so, the code should look like this:
Z = X ^ Y; // find the XOR of X and Y, store in Z
We hope we have provided you with all the information you need about the XOR operator to ace your interview. Good luck on your job meeting from the IT Interview Guide team!
