Checking the public method arguments is necessary to guarantee that methods callers are respecting the class API contract. On the contrary, private methods are not visible to outside code so there is no need the detect contracts violation.

Java Program to Check if a String is Empty or Null In this program, you'll learn to check if a string is empty or null using a method and the if-else statement in Java. To understand this example, you should have the knowledge of the following Java programming topics:

9 Feb 2009 The most common of which is the null check. Than some time later people started doing automated unit-testing, and a weird thing happened,
The method AbstractCharSequenceAssert.isNotEmpty () verifies that the actual CharSequence is not empty, or, in other words, that it is not null and has a length of 1 or more: Assertions (by way of the assert keyword) were added in Java 1.4. They are used to verify the correctness of an invariant in the code.

Assertions.assertNull () checks that object is null. In case, object is not null, it will through AssertError. public static void assertNull (Object actual) public static void assertNull (Object actual, String message) public static void assertEquals (java.lang.Object expected, java.lang.Object actual) Asserts that two objects are equal. If they are not, an AssertionError without a message is thrown. If expected and actual are null, they are considered equal. The post-fix expression operator ! may be used to assert that its operand cannot be null or undefined during runtime.

The correct idiom is to perform the action before the assertion and then assert that the action succeeded: Please note that you need to use JUnit’s org.junit.Assert class in case of JUnit 4 or JUnit 3 to assert using assertNull method. Assertions.assertSame() checks whether expected and actual object refer to same object. In case, both do not refer to same […] "assertNotNull ()" functionality is to check that an object is not null. Since string1= "Junit" which is a non-null value so assertNotNull (string1) will return true. assertNull (string5); "assertNull ()" functionality is to check that an object is null. When we want to assert that an object is not null we can use the assertNotNull assertion.
