This section describes you how to implement assertion in Java. In this tutorial you will learn about what is assertion, how to express assert keyword in Java, where to use assertion in Java, benefits of implementing assertion in Java.
What is assertion ?
Assertion, in computer programming, specifies the true-false statement. This statement is called a predicate and is placed in the program that shows a developer is predicting the predicate is always true there. Assertion helps in to specify the program and explains why program is correct. Function of assertion can be stated as preconditions, postconditions, and invariants of a class.
Where To Use Assertions
Assertion is used in computer programming to make program more readable, user friendly and understanding. We can use assertion in the states as preconditions, postconditions. As well as assertion can also be used in control flow, as invariants of a class.
Assertion In Java
Assertion is also allowed in Java. Java allowed assertion for its features that it have. To use assertion in Java there is a keyword named assert. Assertion in Java validate data at run-time. Assertion in Java is introduced since JDK 1.4.
How to implement assertion in Java ?
Assertion in Java can be implemented using assert keyword in Java. In Java assert keyword can be used/expressed in two ways :
Benefits Of Implementing assertion In Java
