C语言趣味程序百例精解之JAVA实现(56)区分旅客国籍




程序:

public class Test56{
public static void main(String args[]){
new Test56().whereAreYouFrom56();
}

/**
* 56。区分旅客国籍
*
* 1美国,2德国,3英国,4法国,5俄罗斯,6意大利
*/
public void whereAreYouFrom56() {
int count = 0;
for (int a = 1; a <= 6; a++)
for (int b = 1; b <= 6; b++)
for (int c = 1; c <= 6; c++)
for (int d = 1; d <= 6; d++)
for (int e = 1; e <= 6; e++)
for (int f = 1; f <= 6; f++)
if (a != 1
&& a != 5
&& a != 2
&& e != 1
&& e != 2
&& e != 5
&& c != 2
&& c != 1
&& c != 5
&& b != 2
&& f != 2
&& a != 4
&& c != 6
&& b != 1
&& c != 4
&& notEquls(new int[] { a, b, c, d, e,
f })) {
count++;
System.out.print(" a=" + a);
System.out.print(" b=" + b);
System.out.print(" c=" + c);
System.out.print(" d=" + d);
System.out.print(" e=" + e);
System.out.println(" f=" + f);
}
System.out.println("Count =" + count);
}
/**
* 判断是否两两不相等
*/
public boolean notEquls(int[] a) {
if (a == null || a.length == 0 || a.length == 1)
return true;
for (int i = 0; i < a.length; i++) {
for (int j = 0; j < a.length; j++) {
if (a == a[j] && i != j) {
// System.out.println("a[" + i + "]" + a + " a[" + j +
// "]"
// + a[j] + "---");
return false;
}
}
}
return true;
}
}
C:\bat>java Test56
a=6 b=5 c=3 d=2 e=4 f=1
Count =1
a是意大利人,B是俄罗斯人,c是英国人,D是德国人,E是法国人,F是美国人。
