public class IfElseExample { public static void main(String[] args) { int num = 5; if (num > 0) { System.out.println("这是一个正数"); } else { System.out.println("这不是一个正数"); } } } 3. 嵌套的 If-else 语句 在Java中,我们可以在if或else代码块内部嵌套另一个if-else语句,...
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....

if-else-if语句 Java if语句 Java语言中的if语句用于测试条件。如果条件为true,则执行if语句块。 语法: if(condition){// if 语句块 => code to be executed.} Java 执行流程如下图所示 - 1. 示例 publicclassIfExample{publicstaticvoidmain(String[] args){intage=20;if(age >18) { ...
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. ...
java if…else语句简单应用实例 if...else语句是 Java 编程语言中用于控制程序流程的基本条件语句。下面是一个简单的 Javaif...else语句的实例，演示了根据条件执行不同的代码块：public class IfElseExample { public static void main(String[] args) { // 假设有一个变量表示成绩 int score = 75;// 使用...
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...
Example of If and Else You have selected 'Mike'. You have selected 'Jason' You have not selected 'Mike' or 'Jason'. 在这里,如果标签返回true,如果“test”属性中指定的条件返回true。在我们的例子中,我们比较反对“Mike”。如果这个名字是Mike,标签返回true,我们打印的字符串,否则“elseif”块被执行,...
