我们已经看过 java 程序来检查 Armstrong 数字。在本教程中，我们将编写一个 java 程序来打印给定范围之间的 Armstrong 数字。
在此程序中，要求用户输入起始和结束数字，程序然后在这些输入数字之间打印 Armstrong 数字。
package com.beginnersbook;
import java.util.Scanner;
public class JavaExample
{
public static void main(String args[])
{
int num, start, end, i, rem, temp, counter=0;
Scanner scanner = new Scanner(System.in);
System.out.print("Enter the start number: ");
start = scanner.nextInt();
System.out.print("Enter the end number: ");
end = scanner.nextInt();
scanner.close();
//generate Armstrong numbers between start and end
for(i=start+1; i<end; i++)
{
temp = i;
num = 0;
while(temp != 0)
{
rem = temp%10;
num = num + rem*rem*rem;
temp = temp/10;
}
if(i == num)
{
if(counter == 0)
{
System.out.print("Armstrong Numbers Between "+start+" and "+end+": ");
}
System.out.print(i + " ");
counter++;
}
}
// if no Armstrong number is found
if(counter == 0)
{
System.out.print("There is no Armstrong number Between "+start+" and "+end);
}
}
}输出：
