Two NULL values are not equal. Comparing two NULL values yields an unknown value. The IS NULL test converts a NULL persistent field or a single-valued relationship field to TRUE. The IS NOT NULL test converts them to FALSE. Boolean operators and conditional tests use the three-valued logic...
System.out.println(CollectionUtils.isEqualCollection(list1, list2));//true TheisEqualCollection()method returns true when the two collections contain exact same elements with exactly the same cardinalities. Conclusion: In this tutorial, we learned to check if two lists are equals in Java. We now...
An equivalence relation partitions the values it operates over into sets called equivalence classes. All the members of the equivalence class are equal to each other under the relation. An equivalence class may contain only a single member. At least for some purposes, all the members of an ...
If there are cases where you cannot make an existing variable effectively final (because it gets set multiple times), then you can create a new final variable right before invoking the doPrivileged method, and set that variable equal to the other variable. For example: Copy String lib; //...
The code above executes the line that prints “x must be 3” only if the condition (x is equal to 3) is true. Regardless of whether it’s true, though, the line that prints, “This runs no matter what” will run. So depending on the value of x, either one statement or two will...
is a logical operator (less than or equal). All the logical operators in FORTRAN begin and end with a period (.), such as .AND., .OR., .EQ.(equals), and .GT. (greater than). The program can be simplified by using a DO loop, instead of the IF() GO TO structure. A DO ...
