if……else语句

package Lecture;
//导入一个类
//Scanner= 扫描
import java.util.Scanner;
public class IfElseTest {
   
   
     public static void main(String[] args){
   
   
          Scanner scan = new Scanner(System.in);
          //println = print line
          System.out.println("请输入一个整数:");
          int number = scan.nextInt();
          if(number == 0)
          {
   
   
               System.out.println(number+"是最特殊的偶数");
          }
          else if(number % 2 == 0)
          {
   
   
               System.out.println(number+"是偶数");
          }
          else
          {
   
   
               System.out.println(number+"是奇数");
          }
     }
}

Switch…case语句
