Write a Java program to print all unique element in an array
In this demo I have used NetBeans IDE 8.2 for debugging purpose. But you can use any java programming language compiler as per your availability..
import java.util.Arrays; import java.util.Set; import java.util.TreeSet; public class Javaexcercise { public static void main(String[] args) { Integer[] numbers = {1, 1, 2, 1, 3, 4, 5}; Set<Integer> uniqKeys = new TreeSet<Integer>(); uniqKeys.addAll(Arrays.asList(numbers)); System.out.println("uniqKeys: " + uniqKeys); } }
Result:
uniqKeys: [1, 2, 3, 4, 5]
