本文介绍了一个Java程序，该程序用于验证四位卡布列克数（Kaprekar数）。通过输入一个四位数，程序会进行一系列计算直至得出6174这一神奇数字，展示了卡布列克数的独特性质。

public class E201_06_07_验证四位卡布列克数 { public static void main(String[] args) { Scanner scanner = new Scanner(System.in); System.out.println("请输入一个四位数"); int a = scanner.nextInt(); while (a!=6174){ int max = Max(a); int min = Min(a); a = max - min; System.out.printf("%4d-%4d=%4d\n",max,min,a); } } private static int Min(int a) { int a1000 = a/1000; int a100= a/100%10; int a10=a%10/10; int a1=a%10; int temp=0; int [] b = {a1000,a100,a10,a1}; for (int i =0;i<=b.length;i++){ for (int c = 0;c<=b.length-1;c++ ){ if (b[i]<b[c]){ temp =b[i]; b[i]=b[c]; temp = b[c]; } } } return temp= b[0]*1000+b[1]*100+b[2]*10+b[3]; } private static int Max(int a) { int a1000 = a/1000; int a100= a/100%10; int a10=a%10/10; int a1=a%10; int temp; int num =0; int [] b = {a1000,a100,a10,a1}; for (int i =0;i<=b.length;i++){ for (int c = 0;c<=b.length-1;c++ ){ if (b[i]>b[c]){ temp =b[i]; b[c]=b[i]; temp = b[c]; } } } return num= b[0]*1000+b[1]*100+b[2]*10+b[3]; } }
