java中输入一个整数,并计算该书的平方

importjava.util.Scanner;publicclassA{//下面的方法是对单个数求阶乘,并返回publicstaticintjieCheng(intn){intsum=1;for(i

2L你好夸张!把下面代码放到main()方法中Scanners=newScanner(System.in);System.out.println("请输入a的值：");inta=s.nextInt()

publicclassTest{publicstaticvoidmain(String[]args){intarr[]=newint[11];for(inti=10;i

publicclassTest{publicstaticvoidmain(String[]args){inta=1203;intsum=0;while(a/10!=0){sum

楼主你好,这是源程序,是用辗转相除法写的#includeintmax(intp_a,intp_b){\x09if(p_b==0)\x09\x09returnp_a;\x09else\x09\x09re

publicclassFactorial{publicstaticvoidmain(String[]args){if(args.length!=1){System.out.println("请输入n值

我写了一个c语言的!#includemain(){inti,n,sum=1;scanf("%d",&n);for(i=1;i

importjava.util.Scanner;publicclassTest{publicstaticvoidmain(String[]args){System.out.print("请输入第一个整

importjava.util.Scanner;publicclassTest{publicstaticvoidmain(String[]args){Scannersc=newScanner(Syst

importjava.util.Scanner;publicclassjiechen{publicstaticvoidmain(String[]args){Scannerscanner=newScan

#includeintmain(void){\x09intnum,i,j,k,sum;\x09printf("输入一个三位整数!\n");\x09scanf("%d",&num);\x09i=num%

publicstaticvoidtest(){Scannersc=newScanner(System.in);longnum=0,negative=0,positive=0,sum=0;Listnum

1.编译不通过数组定义时,不能使用变量,即使变量已赋值,所以inta[n]；是错的解决方法,你可以直接定义一个大的数组,比如inta[100],然后再用n限制输入的个数2.数组下标是从0~n-1,所以

BufferedReaderbuf=newBufferedReader(newInputStreamReader(System.in));System.out.print("请输入时间(注意格式必须为

importjava.util.Scanner;publicclassgeweiqiuhe2_5{publicstaticvoidmain(String[]args){Scannersc=newSca

publicvoidscanner(){\x09\x09intarr[]=newint[5];//存储输入数据\x09\x09inttemp;\x09\x09\x09\x09//用于数据交换\x09S

importjava.util.Scanner;publicclassTest{publicstaticvoidmain(String[]args){\x05\x05Scannerinput=newS

第一种方法用if判断的importjava.util.Scanner;publicclassA{\x09publicstaticvoidmain(String[]args){\x09\x09Syste

importjava.util.Scanner;publicclassTest20010{publicstaticvoidmain(Stringargs[]){\x05intnum1,num2;\x0

我不会啊啊
