public class DistinctElementsFromArray {

public static void getElements(int[] arr){
System.out.println("UNIQUE ELEMENTS FROM ARRAY : ");
for(int i=0;i<arr.length;i++){
boolean unique = false;
for(int j=0;j<i;j++){
if(arr[i] == arr[j]){
unique = true;
}
}
if(!unique){
System.out.print(arr[i]+",");
}
}
}
public static void main(String[] args) {
int[] arr = {5,2,5,3,2,8,7};
DistinctElementsFromArray.getElements(arr);
}

}
