Java里输入一个数怎么写

packagetest1;importjava.util.Scanner;publicclassTest6{publicstaticvoidmain(String[]args){Scannerinpu

publicclassMax{publicstaticvoidmain(String[]args){int[]a=newint[5];System.out.println("请输入五个数：");Sca

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

#includemain(){inti=0,s=0,n;scanf("%d",&n);while(n>0){s+=n%10;i++;n/=10;}printf("%d%d\n",s,i);}

importjava.math.BigDecimal;publicclassTest{publicstaticvoidmain(String[]args){BigDecimalmul=newBigDe

//只是做了能够显示线圈方框//其他地方楼主自己修改下importjava.awt.BorderLayout;importjava.awt.Container;importjava.awt.Graph

importjava.util.Scanner;publicclassF{\x09publicstaticvoidmain(String[]args){\x09\x09Scannersc=newSca

很简单,如下代码:packagetest;publicclasstest1{publicstaticvoidmain(String[]args){//这获得是一百内的质数for(inti=0;iget

publicclassTest{publicstaticvoidmain(String[]arsg){inttemp=1000009;StringtempStr=1000009+"";//转换成字符串

importjava.util.Scanner;classtest7{publicstaticvoidmain(Stringargs[]){Scannerscan=newScanner(System.

importjava.awt.*;importjava.awt.event.*;publicclassTestWindowClose{publicstaticvoidmain(Stringargs[]

楼上说没错,while(X)是先进行X判断然后再执行{语句体},而do..while则是先执行do{语句体},再判断while(X),这样会导致do..while比while执行语句体的次数多一次再问

importjava.util.*;publicclassMath{publicstaticvoidmain(Stringargs[]){inta,b;Scannersc=newScanner(Sys

代码如下,第一题：输入N的!#include <stdio.h>#include <stdlib.h>int main(void){ &
