【JAVA习题二十一】给一个不多于5位的正整数,要求:一、求它是几位数,二、逆序打印出各位数字。 packageerase;importjava.util.Scanner;publicclass求几位并逆序打印 {publicstaticvoidmain(String[] args) {//TODO Auto-generated method stubScanner in=newScanner(System.in);intn=in.nextInt();intsum = 0;...
public static void test(int num) { String strNum = String.valueOf(num);int dataLength = strNum.length();System.out.println("data Length:" + dataLength);for (int i = dataLength-1; i>=0;i--) { System.out.println(strNum.charAt(i));} } 程序给你，我这没有画图的工具，...
