The given method will return true if the variant will match any possible input(s). This is used for or condition. In the same way, if you want to do &&(and) condition then you just need to used other Java 8 methods: Note: These methods take Predicate as an argument. anyMatch: return true the moment the first predicate returns true otherwise false. One of the Sonar rules is Enum values should be compared with "==". The reasons are as follows: Testing equality of an enum value with equals () is perfectly valid because an enum is an Object and every Java developer knows == should not be used to compare the content of an Object. At the same time, using == on enums:
If you want to compare two different objects to find out whether they're equal, your class that defines those objects generally needs to implement the equals() method. Otherwise Java has no way to know what 'equality' is supposed to mean. That is, your problem is not in the unit test, it's in the class being tested. The unit test did its job :-)
There are some general principles defined by Java SE that must be followed while implementing the equals() method in Java. The equals() method must be: reflexive: An object x must be equal to itself, which means, for object x, equals(x) should return true. symmetric: for two given objects x and y, x.equals(y) must return true if and only if 4 days ago · Since the release of Java 8, it is recommended to migrate to the Java 8 Date/Time API. Similarly to LocalDate and LocalDateTime, both java.util.Date and java.util.Calendar objects have after(), before(), compareTo() and equals() methods for comparing two date instances. The dates are compared as the instants in time, on the level of a millisecond:
