what is input validation in java? | bug bounty | hacker vlog | source code review

#hackervlog #sourcecodereview #security
Input validation is the process of checking user input to ensure that it is valid and safe. This is important for security purposes, as it can help to prevent malicious users from injecting harmful code into your application.

In Java, input validation can be done using a variety of methods, such as:

Regular expressions: Regular expressions can be used to match specific patterns of characters. For example, you could use a regular expression to check if a user input is a valid email address.
Validation annotations: Java provides a set of validation annotations that can be used to validate user input. For example, the @NotNull annotation can be used to check if a user input is not null.
Custom validators: You can also create your own custom validators to validate user input in specific ways.
