Instead of writing many if..else statements, you can use the switch statement. The switch statement selects one of many code blocks to be executed: This is how it works: The switch expression is evaluated once. The value of the expression is compared with the values of each case. If there is a match, the associated block of code is executed.

Apr 11, 2025 · In simple words, the Java switch statement executes one statement from multiple conditions. It is an alternative to an if-else-if ladder statement. It provides an easy way to dispatch execution to different parts of the code based on the value of the expression.

A switch works with the byte, short, char, and int primitive data types. It also works with enumerated types (discussed in Enum Types), the String class, and a few special classes that wrap certain primitive types: Character, Byte, Short, …

The switch statement allows us to execute a block of code among many alternatives. In this tutorial, you will learn about the switch...case statement in Java with the help of examples.

In Java, is it possible to write a switch statement where each case contains more than one value? For example (though clearly the following code won't work): case 1 .. 5: System.out.println("testing case 1 to 5"); break; case 6 .. 10: System.out.println("testing case 6 to 10"); break;

Mar 26, 2025 · In this tutorial, we’ll cover how we can use pattern matching in switch. We’ll also explore some switch specifics, like covering all values, ordering subclasses, and handling null values. 2. Switch Statement. We use switch in Java as a control-flow statement to transfer control to one of the several predefined case statements.

Jun 21, 2022 · You use the switch statement in Java to execute a particular code block when a certain condition is met. Here's what the syntax looks like: switch (expression) { case 1: // code block break; case 2: // code block break; case 3: // code block break; default: // code block}

Jun 11, 2024 · In this tutorial, we’ll learn what the switch statement is and how to use it. The switch statement allows us to replace several nested if-else constructs and thus improve the readability of our code. Switch has evolved over time. New supported types have been added, particularly in Java 5 and 7.

Oct 21, 2023 · In this guide, we’ll walk you through the process of using switch statements in Java, from the basics to more advanced techniques. We’ll cover everything from understanding the basic syntax, handling different types of switch cases, to troubleshooting common issues. Let’s dive in and start mastering the Java switch statement!

The switch statement in Java provides a way to execute one block of code out of many based on the value of an expression. It is an alternative to using multiple if-else-if statements and is especially useful when you have a single variable or expression to evaluate against several possible values.
