class RemoveDuplicates{
public static void main(String[] args){
String[] str = new String[] {
"Where",
"there",
"is",
"will",
"there",
"is",
"a",
"way"};

Arrays.sort(str);

int k = 0;

for (int i = 0; i < str.length; i++){
 if (i > 0 && str[i].equals(str[i -1]))
  continue;
  str[k++] = str[i];
 }
 String[] st = new String[k];
 System.arraycopy(str, 0, st, 0, k);
 for (int i = 0; i < st.length; i++)
 System.out.println(st[i]);
