The following code example displays the type of game based on the value of the String named “game. Also, the comparison of string objects in the switch statement expression is case-sensitive.

The comparison of the string object in the switch statement’s expression with associated expressions of each case label is as if it was using the String.equals method. (“Elective courses : Optimization”) Įlective courses: Big Data, Machine Learning Use of strings in switch statementsīeginning from JDK7, you can use a String object in the expression of a switch statement. (“elective courses : Antenna Engineering”) (“Elective courses : Big Data, Machine Learning”) (“Elective courses : Algebra, Advance English”) The following example demonstrates the use of nested Java switch-case statements: In this case, there is no conflict between the case constants in the other switch and those in the inner switch because a switch statement defines its own block. Nested Java switch case statementsĪ nested switch is when you use a switch as a part of the sequence of statements of an outer switch.

Switch statements in Java can have multiple case labels as well. Java switch statement with multiple case labels The default section in the code handles all values not regulated by any of the case sections. The use of the break statement is helpful because it makes the code less error-prone and modifications easier. Here, the final break statement serves no purpose because the flow falls out of the switch statement. The above code displays the month of the year corresponding to the integer month and the months that follow. The following code is an example to show a switch block falling through in the absence of the break statement. Thus, regardless of the expression of the succeeding case labels, all statements after the matching case label are sequentially executed until a break statement is encountered. The break statement is required because without it, statements in the switch block would fall through. The break statement is an essential aspect of the Java switch case that terminates the enclosing switch statement. Purpose of break statement in Java switch case

The following Java code example declares an int named “month” whose value represents one of the 12 months of the year. No break is needed in the default case.Ĭheck out upGrad’s Full Stack Development Bootcamp (JS/MERN) Example of the Java switch statement below is default statement, used when none of the cases is true. We can have any number of case statements values must be of same type of expression Given below is the syntax of the switch case statement: Java supports three kinds of statements: expression statements for changing values of variables, calling methods and creating objects, declaration statements for declaring variables, and control-flow statements for determining the order of execution of statements.

This article focuses on one such type of selection control mechanism – the Java switch case statement.Ĭheck out our free courses to get an edge over the competition What is a switch case in Java? However, statements that control the program flow (flow-control statements), such as loops and conditionals, do not follow the default order of execution. By default, the Java interpreter follows the order in which statements are written and runs one statement after another. In simpler terms, a Java statement is an instruction explaining what should happen.Ī Java statement ends in a semicolon ( ) and tells Java to process instructions up to that semicolon. Like sentences in the English language that gives a complete idea of the text and include clauses, Java statements are commands including one or more expressions that the Java interpreter executes. The switch case in Java is one of the many Java statements that tell the programming language what to do.
