There are many ways to remove duplicate items
A) Using for Loop
package InterViewQuestions;
public class RemoveDuplicatesFromArray {
public static void main(String[] args) {
Integer[] integer_Array = {50, 50, 100, 100, 99, 99, 9, 9, 100, 100};
int [] temp = new int[integer_Array.length];
for(int i =0; i< integer_Array.length; i++){
for(int j = i+1; j < integer_Array.length-1; j ++ ){
if(integer_Array[i] == integer_Array[j]){
integer_Array[i] =0;
}else{
temp[i] = integer_Array[i];
}
}
}
for(int i =0; i<temp.length; i++){
if(temp[i] !=0){
System.out.println(temp[i]);
}
}
}
}
B) Using set collection
public static void removeDupInIntArray(int[] ints){
Set<Integer> setString = new LinkedHashSet<Integer>();
for(int i=0;i<ints.length;i++){
setString.add(ints[i]);
}
System.out.println(setString);
}
