Question

hello guys i am try to eliminate all the duplicate strings from a string of array and preserve only one string of that…

assume temp[] be the string array and contains

temp[0] = "stack";
temp[1] = "overflow";
temp[2] = "stack";
temp[3] = "stack";
temp[4] = "overflow";

i need only “stack” and “overflow” in this case (it may be stored into another string array) but preserving the order as

temp2[0] = "stack";
temp2[1] = "overflow";

assume temp2 be another string array..

Answer 1

A java.util.LinkedHashSet will remove duplicates while preserving order.

temp = new LinkedHashSet<String>(Arrays.asList(temp)).toArray(new String[0]);
