This code ensures that the `parameter` input cannot be null before continuing with the method logic. 2. Verifying object state:java
This code ensures that the `object` is in an active state before continuing with the method logic. 3. Ensuring logical branches:java public void someMethod(int value) { Assert.isTrue(value > 0, "Value must be greater than zero"); if (value < 10) { // do something } else { Assert.isTrue(value < 50, "Value must be less than fifty"); // do something else } } ``` This code ensures that the `value` input is greater than zero, and then asserts that it is also less than fifty if the `else` branch is reached. The org.springframework.util.Assert package is part of the Spring Framework and can be found in the spring-core module.
