导读：这是我的代码 public class Leapyear{ public static void main(String []args){ for(int year =2000; year =2020; year++){ if((year % 400 == 0) || ((year % 4 == 0) (year % 100 != 0))) System.out.println("Year " + year + " is a leap year"); else

这是我的代码
public class Leapyear{
public static void main(String []args){
for(int year =2000; year <=2020; year++){
if((year % 400 == 0) || ((year % 4 == 0) && (year % 100 != 0)))
System.out.println("Year " + year + " is a leap year");
else
System.out.println("Year " + year + " is not a leap year");
}
但问题是：如果不是闰年,我不知道如何返回true,如果不是闰年,我不知道如何返回false. 解决方法
您可以创建一种方法来判断一年是否是闰年.像这样.
public class Leapyear{
public static void main(String []args){
for(int year =2000; year <=2020; year++){
if(isLeapYear(year)) {
System.out.println("Year " + year + " is a leap year");
else
System.out.println("Year " + year + " is not a leap year");
}
}
public static boolean isLeapYear(int year) {
return (year % 400 == 0) || ((year % 4 == 0) && (year % 100 != 0)) /* It will return boolean value (true or false) */
}
}
