Apr 11, 2025 · The switch statement in Java is a multi-way branch statement. In simple words, the Java switch statement executes one statement from multiple conditions. It is an alternative to an if-else-if ladder statement.

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.

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 …

Jan 15, 2014 · Instead of using switch, just use if. return new A(); return new B(); throw new AssertionError("Unknown type: " + type); This way you can also handle more detailed cases in your if conditions, like subclasses, or interfaces, etc.

Aug 18, 2012 · To illustrate these two methods, consider the following two switch statements: switch (value1) { case 0: a(); break; case 1: b(); break; case 2: c(); break; case 3: d(); break; } switch (value2) { case 0: a(); break; case 35: b(); break; case 103: c(); …

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.

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.

This tutorial has covered fundamental switch statement concepts, advanced expression patterns, and practical implementation strategies, empowering programmers to write more elegant and efficient conditional logic in their Java projects.

Feb 6, 2025 · Let's understand the keywords and syntax necessary to implement a switch case statement in a Java program. Switch Case conditional statements in Java are invoked with the keyword ‘switch’. The syntax to declare a switch case is “ switch () ”, which is used at the beginning of a conditional statement.

In this article, we are going to purely discuss and implement the switch case or switch statement in Java with examples. A Java switch statement is a multiple-branch statement that executes one statement from multiple conditions.
