...else{//code to be executed if all the conditions are false} Java 执行流程如下图所示 - 示例: publicclassIfElseIfExample{publicstaticvoidmain(String[] args){intmarks=65;if(marks <50) { System.out.println("fail"); }elseif(marks >=50&& marks <60) { System.out.println("D grade")...
在项目中创建一个新的Java类,并给它起一个合适的名称,比如IfElseExample。 在IfElseExample类中,添加一个main方法作为程序的入口点。 在main方法中,使用以下代码创建一个简单的if else语句: publicclassIfElseExample{publicstaticvoidmain(String[]args){intnumber=10;if(number>0){System.out.println("The numbe...
public class IfElseExample{ public static void main(String [] args){ int number =13; if (number % 2 == 0){ System.out.println("这是一个偶数。"); }else{ System.out.println("这是一个奇数。"); } } } if(){ //code to be executed if condition1 is true. }elseif(){//code to...
publicclassDynamicIfElseExample{publicstaticvoidmain(String[]args)throwsException{Stringcondition="true";Stringcode="if ("+condition+") { System.out.println(\"Condition is true\"); } else { System.out.println(\"Condition is false\"); }";System.out.println("Dynamic Code:");System.out.print...
This example shows how you can use if..else to "open a door" if the user enters the correct code:ExampleGet your own Java Server int doorCode = 1337; if (doorCode == 1337) { System.out.println("Correct code. The door is now open."); } else { System.out.println("Wrong code....
2. The If-else Example Let’s see an example of anif-elsestatement. In the following program, we check whether the employee’s age is greater than 18. On both bases, we print that the employee is a minor or an adult. intage=employee.getAge();if(age>18){System.out.println("Employe...
}else{ greeting ="Good evening"; } Try it Yourself » More examples below. Description The if/else statement executes a block of code if a specified condition is true. If the condition is false, another block of code can be executed. ...
Scala设计了一种"match"表达式, 它类似于Java中的switch语句, 如下为代码示例: val i = 5 val numberDescription = i match { case 1 => "equals one" case 2 => "equals two" case 11 => "equals three" case _ => "else number" } println(numberDescription) // else number 如代码示例可见, ...
If test_expression2 is True, code block 2 is executed. If test_expression2 is False, code block 3 is executed. Example: R if...else if...else Statement x <- 0 # check if x is positive or negative or zero if (x > 0) { print("x is a positive number") } else if (x < ...
一、ELSEIF在程序设计中的作用 当我们写程序时,经常会遇到需要根据不同条件执行不同操作的情况。ELSEIF允许程序在多种情况下保持高效和有条理。不同的编程语言可能会有点差异,但基本的逻辑是一致的。例如,在C语言或Java中,ELSEIF 语法提供了一个非常清晰的选择结构来处理复杂的条件逻辑。
