Set / Treeset removed at the specified index element

 

　　Treeset set belonging to one set of data type

Requirements: If you are interested in Treeset type, remove the element at the specified index, but did not get under Set () method, the original demand is String [] array of type de-emphasis, use Treeset solve

One of the hardest way to go:

/ ArrayList deduplication
ArrayList<String> result = new ArrayList<String>();
for(String s : unique){
      if(!result.contains(s))
        result.add(s);
}
System.out.print ( "ArrayList deduplication Results:");
for(String s : result){
    //System.out.println(s);
}

　　another:

// Treeset store data in the form of　
TreeSet<String> unique = new TreeSet<String>();
for (String s: exclu) {// String exclu as before []
    unique.add(s);
}

 

turn into a set list can be resolved:

List <datatype> lst = new ArrayList<datatype>(Set); //

lst.get (index); // index to obtain a corresponding element of the index

Liezi corresponding to the above is:

ArrayList <String> arruni = new ArrayList<String>(unique);

for (int i = 0; i < arruni.size(); i++ ) {
  println(arruni.get(i)); 
}
