Output: It has 31 days Explanation of Java Switch multiple cases public class ExampleOfSwitchĭefault: ("Please enter valid input") You can’t provide the break statement in between combined cases. Whenever you want to combine multiple cases you just need to write a case with case labels and colons(:). You can combine multiple cases as you can see in syntax. It means you can combine multiple cases of the Switch statement. So in that case user can combine the case. ![]() It totally depends upon the user because sometimes the user wants to perform the same action on different inputs. You can write multiple cases in combined form in the Switch statement. In this topic, we will see how we can use switch case java with combined cases.Īs you already know the Switch statement, can contain multiple cases. We can use multiple cases in switch statement. In java switch case is used to reduce the complexity of the if-else ladder. Otherwise, the switch case will trigger the default case If marks don’t match with the case, then the default case of the inner switch statement is executed.Ĥ. The inner switch statement is checking the condition and sees the marks of the student. The outer switch statement is checking the condition and sees which year of a student falls in the category ofģ. In the given program we initialized two variables: year and marksĢ. Output: Congrats!!!!! you are eligible for scholarshipġ. ("Congrats!!!!! you are eligible for scholarship") ĭefault: ("Please enter valid year") ("You are not eligible for scholarship") ("Second year students are not eligible for scholarship") ("First year students are not eligible for scholarship ") java switch case example public class ExampleOfNestedSwitch You can use the inner switch statement in the default case of the outer switch statement. ![]() You can’t write inner switch statements outside the cases.Ģ. The inner switch statement must be part of any case of the outer switch statement. An essential point of Nested Switch statements in Javaġ. If it returns true then the control flow enters the inner Switch statement. Step3: JVM will check the condition of the inner switch statement. Step2: JVM will execute the block statement with the matched case. If it returns true then control flow enters the outer Switch statement. Step1: JVM will check the condition of the outer switch statement. If the condition of the outer switch statement is true the JVM checks the condition of the inner switch statement. The inner switch statement can be part of any case of an outer switch. This is known as the Nested switch-case statements in Java. We can use a switch statement inside another switch statement. There are some rules or important points that help you to understand them better. Let’s discuss the nested switch in java programs. Here, we created three cases of int type and each case has different codes according to our requirements. The switch expression variable is a type of int. Here we declared a variable and used it in the switch expression. In this example, we want to print the name of months based on their days. ![]() ("April, June, August, October, December has 30 days") Ĭase 31: ("January, March, May, July, September, November hasĭefault: ("Please enter valid no of days") Declaring a variable for switch expression Switch case program in java public class ExampleOfSwitch If all of the above cases are false then JVM executes the default case and the default case doesn’t need a break statement. The default case is optional for the switch case and it must be placed at the end of the switch statement.If we don’t use the break statement in any case then JVM doesn’t break the execution follow until it finds the break statement or the end of the switch statement.Switch statement uses it to terminate a statement sequence and jumps the control after the switch expression. Each case has a break statement which is optional.If you create a duplicate case value, it will throw a compile-time error. The case value type should be a type of expression. ![]() The case value must be literal or constant.You can create any number of cases in the switch statement.You can place a variable or an expression in between the brackets of the switch(). An expression can be of byte, short, int, long, enum types, String, and some wrapper types like Byte, Short, Int, and Long.In the switch statements, we have a number of choices and we can perform a different task for each choice. The switch statement executes one block of the statement from multiple blocks of statements based on condition. Why does float values are not allowed in the switch statement? Here is the table content of this article we will cover all the parts of this topic.ĥ. Youtube video available in the Hindi language – Java Programming Goal
