方法一：
1 package qqq; 2 3 public class Jiou { 4 5 public static void main(String[] args) { 6 // TODO Auto-generated method stub 7 int x=233; 8 switch(x%2)//取x除以2的余数 9 { 10 case 0://余数为0则x为偶数 11 System.out.println("x是偶数"); 12 break; 13 default://否则为奇数 14 System.out.println("x是奇数"); 15 }//switch分支判断语句 16 } 17 }
方法二:
1 package qqq; 2 3 public class Jiou { 4 5 public static void main(String[] args) { 6 // TODO Auto-generated method stub 7 int x=45; 8 System.out.println(x%2==0?"偶数":"奇数"); 9 } 10 }
方法三：
1 package qqq; 2 3 public class Jiou { 4 5 public static void main(String[] args) { 6 // TODO Auto-generated method stub 7 int x=2; 8 if(x%2==0) 9 { 10 System.out.println("x是偶数"); 11 } 12 else 13 { 14 System.out.println("x是奇数"); 15 } 16 } 17 }
