怎么去掉字符串数组中重复的值

Answer 1

import java.util.Set;
import java.util.TreeSet;

public class Admin {
public static void main(String[] args) {
String fdbs = "WXB,WXA,FDA,WXB";
String[] str = fdbs.split(",");
Set set = new TreeSet();
for (int i = 0; i < str.length; i++) {
set.add(str[i]);
}
str = (String[]) set.toArray(new String[0]);
for (int i = 0; i < str.length; i++) {
System.out.println(str[i]);
}
}
}
