JAVA中如何计数或如何进行标记

例如我要计算出2015-1900，年之间所有闰年的个数或标记出闰年，该利用哪些代码完成

public class SelectSort {
public static void main(String[] args) throws IOException{
for (int i = 1900; i <= 2015; i++) {
if(i%100==0){
if(i%400==0){
System.out.println(i+"是闰年");
}
}else{
if(i%4==0){
System.out.println(i+"是闰年");
}
}
}
}
}

 public class RunNian {
    private int startYear = 0;
    private int endYear = 0;
    private ArrayList<String> runnianList = new ArrayList();
    public RunNian(int startYear,int endYear){
        this.startYear = startYear;
        this.endYear = endYear;
    }
    public void cal(){
        for(int year = startYear;year<=endYear;year++){
            if((year%4==0&&year%100!=0)||year%400==0){
                runnianList.add(year+"");
            }
        }
    }
    public int getCount(){
        return this.runnianList.size();
    }
    public void printRN(){
        for(int i=0;i<this.runnianList.size();i++){
            System.out.println(this.runnianList.get(i));
        }
    }
    /**
     * @param args
     */
    public static void main(String[] args) {
        RunNian rn = new RunNian(1900,2015);
        rn.cal();
        System.out.println("润年数量："+rn.getCount());
        System.out.println("润年列表:");
        rn.printRN();
    }

}

如果有帮助，顺手采纳一下哦

建个栈，是闰年就进栈，数据，列表同理

我是使用List来存放所有的闰年，而判断闰年的方式是根据Calendar的属性来进行判断，代码比较短，请参考：


import java.util.ArrayList;
import java.util.Calendar;
import java.util.List;

/**
 * 主要是求闰年方法的一种演示，可以通过判断每年的最后一天是否是第366天来进行闰年的判断
 */
public class LeapYearDemo {
    public static void main(String[] args) {
        int startYear = 1900;
        int endYear = 2015;

        List<Integer> leapYearList = getLeapYearList(startYear, endYear);

        System.out.println("起始年份（包含）" + startYear + "-截止年份（包含）" + endYear
                + "之间的闰年年份共有" + leapYearList.size() + "个，分别是：");
        for (Integer leapYear : leapYearList) {
            System.out.print(leapYear + "\t");
        }
    }

    /**
     * 获取给定年份之间的所有闰年年份，包含起始和截止年份
     * <p>
     * 主要通过Calendar类的DAY_OF_YEAR属性来判断每年的最后一天是否是第366天
     * 
     * @param startYear
     * @param endYear
     * @return
     */
    private static List<Integer> getLeapYearList(int startYear, int endYear) {
        List<Integer> leapYearList = new ArrayList<Integer>();
        // 获取当前日期，无所谓，后面会改为12月31日，循环中改年份
        Calendar _cal = Calendar.getInstance();
        _cal.set(Calendar.MONTH, 11);
        _cal.set(Calendar.DAY_OF_MONTH, 31);
        for (int i = startYear; i <= endYear; i++) {
            _cal.set(Calendar.YEAR, i);
            if (_cal.get(Calendar.DAY_OF_YEAR) == 366) {
                leapYearList.add(i);
            }
        }
        return leapYearList;
    }
}

运行结果：

起始年份（包含）1900-截止年份（包含）2015之间的闰年年份共有28个，分别是：
1904    1908    1912    1916    1920    1924    1928    1932    1936    1940    1944    1948    1952    1956    1960    1964    1968    1972    1976    1980    1984    1988    1992    1996    2000    2004    2008    2012

简单的话就用两个数组来分别存放，先进行判断
