switch statement java

Statement (first published in www.kunwsoft.com) It is certainly not unfamiliar to the switch statement, which allows the program to choose from multiple actions based on the value of the control expression (If-else somewhat similar to the multiple-spoke statement, from a logical process). This is also true in C + + and

(First published on www.kunwsoft.com)?????? ? You must be familiar with the switch statement. Program Select multiple actions based on the value of the control expression (from the logic process perspective, it is somewhat similar to the multi-branch statement if-else ). This statement is also available in C ++ and

How to let the switch statement jump out and execute it down $ Type = $ _ POST ['type']; // You do not need to log on to switch ($ type) {case 1: // SQL read data 1 $ acase 2: // SQL read data 2 $ a} if ($ a) {}// if any data is read, an error die is returned; if ($ user) {}// verify whether or not to log on // after logging on,

In summary, the use of switch is to determine if the expression after the case matches the expression after switch, and once the case is matched, the subsequent program code is executed, regardless of whether the following case matches until the break was met . Do not match to find default. No matter where default is placed. As soon as a junction (case or default) enters, it executes the following code in

The Switch statement in PHP is used to execute different actions based on multiple different conditions. Switch statement if you want to selectively execute one of several code blocks, use the Switch statement. Use the

4.3.3 Switch statementThe switch statement is very similar to an if statement because it is also conditionally executing code based on the value of the test. However, a switch statement can compare a test variable to more than one

This is a creation in Article, where the information may have evolved or changed. This is the 10th article in the [Golang Series Tutorial] (/SUBJECT/2). Switch is a conditional statement that compares the value of an expression to a list of options that might match, and executes the corresponding block of code based on the matching situation. It can be thought of as a common way to replace multiple ' if El

Switch statements are also the most common logical control statements in object-oriented programming. The Switch statement is used to execute different actions based on multiple different conditions-that is, when the conditions are different, different logical operations are executed. Switch statements are also the mos

Explanation of switch statement usage in JavaScript This article describes how to use the switch statement in JavaScript. It is the basic knowledge in JS learning. For more information, see You can use multiple if... else if statements, such as the previous chapter, to execute multiple branches. However, this is not al

In the code business, conditional judgment is essential, and the statements that control the flow are similar in each language. Swift includes the following:If,switch,for-in,for,while,do-whileIf condition statement (if-else) (If ... else)Executes the relevant code when the condition is true. For example:var a = 0If a > 0 {println ("a > 0")}else if a = = 0{println ("a = 0")}else{println ("a }The

Sometimes, when the IF statement is nested, all if statements look very similar because they are evaluated for an exact same expression, with the only difference being that each if statement compares the result of the expression with a different value. For example: if (day == 0) 　dayName = "Sunday"; else if (day == 1) 　dayName = "Monday"; else if (day == 2) 　dayName = "Tuesday"; else if (day == 3) 　... els

When I first started writing a program, I liked to write if (){...} else if (){...} else {...}, as a result, my program seems to be an if statement. Some people once mentioned it to me, but I did not agree with it. I thought about how to implement it. Why should the program be so fancy and start to despise others, but .. When I tried to use a switch, I found that I made a big mistake. The program is not onl

Switch is the most flexible type of control statement, which you need to be aware of when using switch:--The left curly brace "{" must be in the same row as switch--Conditional expressions are not limited to constants or integers--Multiple result options can appear in a single case--contrary to the rules of C, G0 langu

In the process of PHP web development, the speed of the website is closely related to the simplicity and complexity of the code. For example, when we need to specify a variety of conditions to execute different blocks of code, it is necessary to use the PHP related conditional statements, then how to use concise code to implement the multi-conditional judgment statement? This article will give you a detailed introduction to the specific use of PHP

If statements process two branches, the IF-else-If structure must be used when processing multiple branches. However, if there are many branches, the more nested if statement layers,ProgramIt is not only huge but also difficult to understand. Therefore, the C language provides a conditional selection statement specifically used to process multi-branch structures, calledSwitch

Let's talk about the format of the switch () statement switch (expression) { Case Match 1: When matching 1 and the expression match the successful execution of the Code; Break Case Match 2: When matching 2 and the expression match the successful execution of the Code; Break Default If the case statement does not hav

A common problem in programming is to detect whether a variable conforms to a condition, and switch implements a "Multiple choice" option in a straightforward way, with the following syntax:/*switch evaluates the expression first, and executes several statements after the case statement until a break is encountered if the value of the expression is the same as th

Write a program that receives a number and displays dependent information based on user input. The switch statement is required, for example, 1, 2, 3, display, Monday, Tuesday, and Wednesday, // Author: Janushu // Date: 2017/9/20/* function: write a program that can receive a number and display dependent information based on user input, the switch

The usage of the switch statement in JavaScript is described in detail. You can use multiple if... else if statements, such as the previous chapter, to execute multiple branches. However, this is not always the best solution, especially when all branches depend on the value of a single variable. Starting with JavaScript1.2, you can use it to handle this situation. Using a
