将整数分解成数位的Java程序

编写一个Java程序，使用while循环将整数分解成数字。在这个Java例子中，第一个while循环将计算一个数字的总位数。第二个while循环将遍历整数并打印每个数字作为输出。

package RemainingSimplePrograms;

import java.util.Scanner;

public class DigitsinNumber1 {
	private static Scanner sc;
	public static void main(String[] args) {
		int num, reminder, temp, count = 0;
		sc = new Scanner(System.in);		
		System.out.print("Please Enter Any Number = ");
		num = sc.nextInt();
		
		temp = num;
		
		while(temp > 0)
		{
			temp = temp / 10;
			count++;
		}
		
		while(num > 0)
		{
			reminder = num % 10;
			System.out.println("Digit at Position " + count +  " = " + reminder);
			num = num / 10;
			count--;
		}
	}
}

Please Enter Any Number = 98453217
Digit at Position 8 = 7
Digit at Position 7 = 1
Digit at Position 6 = 2
Digit at Position 5 = 3
Digit at Position 4 = 5
Digit at Position 3 = 4
Digit at Position 2 = 8
Digit at Position 1 = 9

使用for循环将整数分解成数字的Java程序。

package RemainingSimplePrograms;

import java.util.Scanner;

public class DigitsinNumber2 {

private static Scanner sc;

public static void main(String\[\] args) {
	
	int num, reminder, temp, count = 0;
	
	sc = new Scanner(System.in);
	
	System.out.print("Please Enter Any Number = ");
	num = sc.nextInt();
	
	for(temp = num; temp > 0; count++)
	{
		temp = temp / 10;
	}
	
	for(;num > 0; num = num / 10)
	{
		reminder = num % 10;
		System.out.println("Digit at Position " + count +  " = " + reminder);		
		count--;
	}
}
