（基础二）java if语句学习

public class IFTest {

public static void main(String[] args) {
//需求1：根据定义的数据，打印对应的星期的英文

/*      int x = 6;

if(x == 1){
System.out.println("Monday");
}else if(x == 2){
System.out.println("Tuesday");
}else if(x == 3){
System.out.println("Wednesday");
}else if(x == 4){
System.out.println("Thursday");
}else if(x == 5){
System.out.println("Friday");
}else if(x ==  6){
System.out.println("Saturday");
}else if(x == 7){
System.out.println("Sunday");
}else{
System.out.println("输入数据错误！");
}*/

//需求2：根据用于指定月份，打印该月份所属的季节。
//3,4,5 春季 6,7,8 夏季  9,10,11 秋季 12, 1, 2 冬季

//方法一：
/*      int month = 6;

if(month == 1 || month == 2 || month == 3)
{
System.out.println(month+"月份是春季");
}else if(month == 4 || month == 5 || month == 6){
System.out.println(month+"月份是夏季");
}else if(month == 7 || month == 8 || month == 8){
System.out.println(month+"月份是秋季");
}else if(month == 10 || month == 11 || month == 12){
System.out.println(month+"月份是冬季");
}else{
System.out.println("月份不存在！");
}*/

//方法二：
int month = 6;

if(month >= 1 && month <= 3){
System.out.println(month+"月份是春季");
}else if(month >= 4 && month <= 6){
System.out.println(month+"月份是春季");
}else if(month >= 7 && month <= 9){
System.out.println(month+"月份是春季");
}else if(month >= 10 && month <= 12){
System.out.println(month+"月份是春季");
}else{
System.out.println("月份不存在");
}
}
}
