In Java, wrapper classes like an integer or a character encapsulate primitive data types. These wrappers can be used in switch cases, but it is important to note that switch cases typically expect constant expressions known at compile time. Example: public class WrapperSwitchExample { public stati...
default Case in Java switch-case The switch statement also includes an optional default case. It is executed when the expression doesn't match any of the cases. For example, class Main { public static void main(String[] args) { int expression = 9; switch(expression) { case 2: System.ou...
Compound cases.Next is dealing with multiple case labels. Before Java 12, you could use only one label for each case. For example, in the following code, despite the fact that the logic forSTOPandPAUSEis the same, you’d need to handle two separate cases unless you use fall through: Cop...
In this example,numis 1, which matches the first case. However, because there’s no break statement after the first case, Java ‘falls through’ to the second case and executes that as well, resulting in both ‘One’ and ‘Two’ being printed. Understanding this ‘fall through’ behavior ...
Java example to demonstrate an enum in switch case. Submitted byNidhi, on April 04, 2022 Problem statement In this program, we will create avehicleenumeration using "enum" inside the classMain. Then we will use an enum constant with a switch case inside themain()method and print the approp...
Main.java void main() { String[] planets = { "Mercury", "Venus", "Earth", "Mars", "Jupiter", "Saturn", "Uranus", "Pluto" }; for (String planet : planets) { System.out.println(planet); } } In this example, we use the enhancedforstatement to go through an array of planets....

Consider a business scenario where a product’s discount is dependent on a single, specific case. The main difference from the earlier example is that the discount for the discontinued and refurbished products is the same, but discount values are not added one after another, as shown inFigure ...
In this example there will be no match for x: Example letx ="0"; switch(x) { case0: text ="Off"; break; case1: text ="On"; break; default: text ="No value found"; } Try it Yourself » Track your progress - it's free!
In the above example, we have assigned4to thedayOfWeekvariable. Now, the variable is compared with the value of each case statement. Since the value matches withcase 4, the statementprint("Wednesday")inside the case is executed, and the program is terminated. ...
