1、题目：输入某年某月某日，判断这一天是这一年的第几天？packageText1;importjava.util.Scanner;publicclassText4{publicstaticvoidmain(String[]args){Scannerscanner1=newScanner(System.in);System.out.print("输出今年是第几年");intyear=scanner1.nextInt();System.out.print("输出今年是第几月");intmouth=scanner1.nextInt();System.out.print("输出今年是第几日

2、");intday=scanner1.nextInt();intday1=0;//天数if(year%400==0&&year%100!=0

3、

4、year%100==0){//判断是否为闰年int[]mouth1=newint[]{31,29,31,30,31,30,31,31,30,31,30,31};//闰年里的每个月的天数for(intmouth2=1;mouth2<=mouth;mouth2++){if(mouth2==1){day1=day;}else{day1+=mouth1[mouth2-2];}}}else{int[]mouth1=newint[]{31,28,3

5、1,30,31,30,31,31,30,31,30,31};//mouth1[]={31,28,31,30,31,30,31,31,30,31,30,31};for(intmouth2=1;mouth2<=mouth;mouth2++){if(mouth2==1){day1=day;}else{day1+=mouth1[mouth2-2];}}}System.out.println("这一天是这一年的第"+day1+"天！");}}
