Case Structure In Java
Unlike if-then and if-then-else statements, the switch statement can have a number of possible execution paths. 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, and Integer discussed in Numbers and Strings.
The syntax of Switch case statement looks like this - switch variable or an integer expression case constant Java code case constant Java code default Java code Switch Case statement is mostly used with break statement even though it is optional. We will first see an example without break statement and then we will
A switch statement in java checks if a variable is equal to a list of values. The variable in the switch statement can be a byte, short, int, or char. However, Java 7 supports also switch statements with Strings. We will see such an example in the next sections. 1. Syntax of Java switch case. The syntax of a switch case statement is the following
These cases are based on some expression or condition. Mostly, the Java Switch statement has proven to be a better alternative for decision-making than the Java if-else statement. Q 2 How do you write a Switch statement in Java? Answer Given below is a sample program where we have used the Switch statement. Here, we have taken an integer

The default case in a switch statement specifies the code to run if no other case matches. It can be placed at any position in the switch block but is commonly
What Is A Switch Case In Java? Java switch statement is like a conditional statement which tests multiple values and gives one output. These multiple values that are tested are called cases. It is like a multi-branch statement. After the release of java 7 we can even use strings in the cases. Following is the syntax of using a switch case in Java.
Java switch Statement. Java switch statement allows a variable to be tested for equality against a list of values. Each value is called a case, and the variable being switched on is checked for each case. The switch statement can be used when multiple if-else statements are required. It can have multiple code blocks along with the case values and execute one of many code blocks based on the
The switch statement or switch case in java is a multi-way branch statement. Based on the value of the expression given, different parts of code can be executed quickly. The given expression can be of a primitive data type such as int, char, short, byte, and char. With JDK7, the switch case in java works with the string and wrapper class and enumerated data type enum in java.
This article helps you understand and use the switch case construct in Java with code examples. The switch-case construct is a flow control structure that tests value of a variable against a list of values. Syntax of this structure is as follows switch expression case constant_1 statement 1 break case constant_2 statement 2 break case constant_3 statement 3 break
