第5题:

注意:不改动程序的结构,不得增行或删行。

import java.io.*;

public class LeapYear

{

public static void main(String args[])

{

int year=1979;

if((year %4= =0 || year % 100 !=0) || (year % 400= =0))

System.out.println(year+"是闰年.");

else

System.out.println(year+"不是闰年。");

year=2000;

boolean leap;

if(year % 4 !=0)

leap=false;

else if(year % 100 !=0)

leap=true;

else if(year % 400 !=0)

leap=false;

else

leap=true;

if(______)

System.out.println(year+"是闰年。");

else

System.out.println(year+"不是闰年。");

year=2010;

if(year % 4= =0)

{

if(year % 100= =0)

{

if(year % 400= =0)

leap=true;

else

______

}

else

leap=false;

}

if(1eap= =true);

System.out.println(year+"是闰年。");

else

System.out.println(year+"不是闰年。");

}

}


正确答案:(year%4= =0&&year%100!=0)||(year%400 ==0) Year%4==0
(year%4= =0&&year%100!=0)||(year%400 ==0) Year%4==0 解析:本题综合考查Java语言的数据类型及运算和分支语句。第1处的错误是:(year%4==0||year%100!=0)||(year%400==0);闰年的条件是符合下面二者之一:①能被4整除,但不能被100整除;②能被4整除,又能被100整除。因此判断某一年是否为闰年的表达式应该为(year%4==0&&year%100!=0)||(year%400==0)。第2处的错误是year%4!=0;应该填写year%4==0,用来判断该年是否能被4整除。
