在jcreator中非法表达的开始

Question

我不确定为什么会出现错误，该错误一直表示存在非法表达的错误并且＆＃39;）＆＃39;是预期的错误。它发生在第14行。

1 import java.io.*;
2 public class LeapYear{
3 public static void main(String[] args){
4   String leapYear="";
5   int intleapYear;
6   
7   BufferedReader input = new BufferedReader(
8       new InputStreamReader(System.in));
9       
10  try{
11      System.out.print("Enter a year: " +leapYear);
12      leapYear=input.readLine();
13      intleapYear=Integer.parseInt(leapYear);
14      boolean isleapyear= ((intleapYear%4==0)&&(intleapYear%100!==0)||(intleapYear%400==0));
16      
17      
18  if(isleapyear){
19      System.out.println(intleapYear + " is a leap year.");           
20  } else
21  System.out.println(intleapYear + " is not a leap year.");
22                     
23  }catch(IOException e){
24      System.out.println("Error");
25  }
26  
27
28      
29  
30  /*if ((intleapYear%4==0)&&(intleapYear%100!==0)||(intleapYear%400==0)){
31          System.out.println(intleapYear+" is a leap year.");
32      }else
33      System.out.println(intleapYear+" is not a leap year.");*/
}

}

Answer 1

这是因为您使用的是!==

你应该使用!=

所以第14行将是：

boolean isleapyear= ((intleapYear%4==0)&&(intleapYear%100!=0)||(intleapYear%400==0));
