java从指定数组中取不重复的7个随机数
如何用java从指定数组中取不重复的7个随机数，以下是我写的代码，但是是有重复的，哪位大侠赐教一下如何使用Random类的种子，帮我实现不重复的随机数。。。
import java.util.*;

public static void main(String[] args)

StringBuffer str1=new StringBuffer();
for(int i=0;i<6;i++)
{
str1.append(data1[r.nextInt(11)]);
}
System.out.println(str1);
}
}
char []a={'v','f',',','e','f'};
Arrays.sort(a);
for(char b:a)
{
System.out.println(b);
