In this example, we have a list of integers that we want to sort in ascending order. We use theCollections.sort()method to sort the list, and then print the sorted list to the console. The output shows the list sorted in ascending order. This is a basic way to sort a list in Jav...
Using the break statement is particularly useful when searching for a specific value in an array or when you want to stop processing once a certain condition is met. It helps keep your code clean and efficient by avoiding unnecessary iterations. Breaking Out of Nested Loops In some cases, you...
In Java, interface names, generally, should beadjectives. Interfaces should be in the title case with the first letter of each separate word capitalized. In some cases, interfaces can benounsas well when they present a family of classes e.g.ListandMap. ...
there is always at least one execution of the code block before the loop control condition is evaluated. If the condition is true, the loop will continue additional iterations until it is no longer true. Because of this,do-whileloops are useful in cases like asking a question and having the...
(in some cases almost separate) from code. If you google “XML vs. annotations”, you will find a lot of interesting debates. Interesting point is XML configurations were introduced to separate configuration from code. Last two statements might create a doubt in your mind that these two are ...
calculation. we always have an option to use the values as different conditions in nested if statements or switch cases, but let’s design an alternate way of delegating the logic to the enum itself. we’ll define methods for each of the enum values and do the calculation. for instance: ...
In other cases, and for long-lived applications in particular, the message might be an indication that we’re unintentionallyholding references to objects, preventing the garbage collector from cleaning them up.This is the Java language equivalent of a memory leak. (Note: APIs called by an appli...
We get the value from the enum using the constant’s name likeDays.MONDAYwill fetch the constantMONDAY, and it will be stored in the enum objectday. We can use it to switch between cases.switch()takes in the value to switch, that isday. At last, we specify each case and the output...
