Switch Statement in Java - Learn how to use the switch statement in Java effectively with examples and syntax details.
A unique characteristic of the switch statement in Java is the ‘fall through’ behavior. When a match is found in the case values, and there’s no break statement to terminate the current case, Java will execute all subsequent cases until it encounters a break statement or reaches the end ...
The default label is optional. there can be at most one default label in a switch statement. For example, Demo publicclassMain {publicstaticvoidmain(String[] args) {inti = 10;//www.java2s.comswitch(i) {case10:// Found the matchSystem.out.println("Ten");// Execution starts herecase20...
Switchhas evolved over time. New supported types have been added, particularly in Java 5 and 7. Also, it continues to evolve —switchexpressions will likely be introduced in Java 12. Below we’ll give some code examples to demonstrate the use of theswitchstatement, the role of thebreakstatem...
Now, the same above program is also done with switch statement for comparison /* Enter a value between 1 & 4 and print it in words using switch command. */ import java.io.*; class SwitchExample { public static void main(String args[] ) ...
Enumtypes(added in Java 5) Stringclass(added in Java 7) HerelabelOne,labelTwoandlabelThreeare “compile-time constant expressions” orconstants(the value of the labels must be known at compile-time). We can achieve similar functionality with a chain ofif-else blocks, but theswitchstatement is...

Java Switch Statements Instead of writingmanyif..elsestatements, you can use theswitchstatement. Theswitchstatement selects one of many code blocks to be executed: SyntaxGet your own Java Server switch(expression){casex:// code blockbreak;casey:// code blockbreak;default:// code block}...
Switch case statement is used when we have number of options (or choices) and we may need to perform a different task for each choice. The syntax of Switch case statement looks like this – switch (variable or an integer expression) { case constant: //Ja
Java 14 introduces a new syntax for theswitch-casestatement. Users can add multiple values for a singlecaseby separating the comma, and users have to put the executable code in the curly braces. In this section, we’ll explore the significance of arrow syntax and demonstrate how it simplifies...
