![]() ![]() No Partial Matches: Because the "switch" statement does not support partial matches, substring-containing strings or expressions cannot be matched using it.Limited Case Expressions: Because the "switch" statement only supports a small number of case expressions, it can be challenging to manage large sets of conditions.Limited Expression Evaluation: Because the "switch" statement only assesses the value of a single expression, complex conditions or expressions cannot be evaluated using.Code Simplifier: The "switch" statement can be used to simplify complex conditional statements and organize code.ĭisadvantages of the "switch" statement in Java.Faster Execution: Generally, the "switch" statement is faster than multiple "if-else" statements, especially when there are many conditions to evaluate.Readability: Using a "switch" statement instead of multiple "if-else" statements makes the code more readable and easier to understand. ![]() Of code and print different messages to the console depending on the value of "i." Advantages of the "switch" statement in Java The java switch statement successively checks the value of an expression with a list of integer or character constants. The "switch" statement will execute different blocks The switch statement is a control flow statement used in Java, which means that it determines the flow of program execution. If the value of the expression does not match any of the case values, the statements following the default label execute. The Java program iterates from 0 to 14, and a "switch" statement is used to evaluate the value of "i" during each iteration. Take, for example, the following program: If the "break" is omitted, execution will proceed to the next "case." It is sometimes desirable to have multiple cases with no "break" I is greater than 5, no case statements match, so the default statement is executed. In contrast, the code associated with "default" isĪs you can see, each time through the loop, the statements associated with the case constant that matches i are executed. The code block associated with these case values is run. When the value of "i" is zero, one, two, three, four, or five. If none of the cases correspond to the value of "i" the "default" case is executed. ![]() If the value of "i" corresponds to a case, the code contained within that case is executed. The expression being evaluated in this program is the variable "i." There are several cases in the "switch" statement, each of which corresponds to a different value of "i." Java's "switch" controlįlow statement enables the program to run various code blocks depending on the result of an expression. This Java program employs a "switch" statement to determine the value of the variable "i" and run various blocks of code in accordance with that value. ![]()
