JAVA过滤掉字符串数组中重复的值

</pre><pre name="code" class="html">String test = "aa,bb,cc,dd,bb";String[] str = test.split(",");TreeSet<String> tr = new TreeSet<String>();

for (int i = 0; i < str.length; i++) {      tr.add(<span style="font-family: Arial, Helvetica, sans-serif;">str</span>[i]);}

String[] str2 = new String[tr.size()];//新定义一个tr长度的数组

for(int i=0;i<str2.length;i++){

  str2[i] = tr.pollFirst();// 从TreeSet中取出元素(不重复)重新赋给数组

}
