package com.sample.pack;
import java.util.ArrayList;
import java.util.List;
public class Duplicates {
/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
int k = 1;
String[] str = { "abc", "123", "tyu", "xyz", "123", "m",
"abc", "abc" };
boolean isDuplicate = false;
List<String> list = new ArrayList<String>();
for (int i = 0; i < str.length; i++) {
for (int j = k; j < str.length; j++) {
if (str[i].equals(str[j].toString())) {
isDuplicate = true;
}
}
k = k + 1;
if(isDuplicate == false){
list.add(str[i]);
}
isDuplicate = false;
}
Object[] afterDuplicate = list.toArray();
for(int i=0; i<afterDuplicate.length; i++){
System.out.println(afterDuplicate[i]);
}
}
