Trinocular operation to determine leap year

• Any year input by the user that is divisible by 4 but not divisible by 100, or divisible by 400, is a leap year. (result: output leap year or common year)
• Ternary operator, its format is: expression? statement1: statement2;

• import java.util.Scanner;
  
  public class Year {
  	public static void main(String[] args) {
  		Scanner scan = new Scanner(System.in);
  		System.out.println("Please enter a year: ");
  		int year = scan.nextInt();
  		String Y;
  		if(year<=0){
  		    System.out.println("The year entered is incorrect, please enter a number greater than 0");
  		}
  		Y = (year % 4 ==0 && year % 100 != 0 || year % 400 == 0) ? (String) "闰年" : (String) "平年";
  		System.out.println(year + "年是" + Y + "！");
  	}
  }
