1、importjava.util.Scanner;publicclassExample1{publicstaticvoidmain(String[]args){Scannersc=newScanner(System.in);//输入一个数字intscore=sc.nextInt();//将数字放入整型score中if(score>0)//if语句进行判断{if(score>=90){System.out.println("你很棒！");}elseif(score>=60&&score<90){System.out.println("你很不错!");}el

2、seSystem.out.println("你得加油!");}elseSystem.out.println("你输入的数字不正确！");}}importjava.util.Scanner;publicclassExample2{publicstaticvoidmain(String[]args){Scannersc=newScanner(System.in);//动态输入任意两个数inta=sc.nextInt();intb=sc.nextInt();if(a>b)//if语句比较大小{System.out.println("你所输入的最大值："+a)

3、;System.out.println("你所输入的最小值："+b);}elseif(a

4、.out.println("1-100的累加和为:"+s);}publicclassExample4{publicstaticvoidmain(String[]args){System.out.println("1-900的水仙数是：");for(inti=100;i<=900;i++)//分析：利用for循环控制100－999个数，每个数分解出个位，十位，百位。{inta=i/100;intb=(i/10)%10;intc=(i%100)%10;if(i==a*a*a+b*b*b+c*c*c){System.out.println(+i+"="+a+

5、"的三次方+"+b+"的三次方+"+c+"的三次方");}}}}publicclassExample5{publicstaticvoidmain(String[]args){//请输出9*9乘法表for(inti=1;i<=9;i++){for(intj=1;j<=i;j++){ints=i*j;System.out.print(+i+"*"+j+"="+s);System.out.print("");}System.out.println("");}}}importjava.util.Calendar;importjava.util.Scanner;

6、publicclassF1{publicstaticvoidmain(String[]args){//输入的年份Scannera=newScanner(System.in);intyear=a.nextInt();System.out.println("输入的年份为："+year);//输入的月份Scannerb=newScanner(System.in);intmonth=b.nextInt();System.out.println("输入的月份为："+month);//titleSystem.out.println("<<<<<<<<<<<<<迷你

7、版万年历>>>>>>>>>>>>");System.out.println(""+year+"年"+month+"月");Stringtitle[]={"日","一","二","三","四","五","六"};for(inti=0;i<=6;i++){System.out.print(title[i]+'t');}System.out.println("");//导出日历类Calendarcal=Calendar.getInstance();//查看1号为星期几cal.set(Calendar.YEAR,year);cal.set(Calendar.

8、MONTH,month-1);//0-11cal.set(Calendar.DATE,1);/
