Introduction
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..
Write a Java program to find the duplicate values of an array of integer values
import java.util.Arrays;
public class Javaexcercise {
public static void main(String[] args)
{
int[] my_array = {1, 2, 3, 4, 5, 6, 7, 2, 3, 4};
for (int i = 0; i < my_array.length-1; i++)
{
for (int j = i+1; j < my_array.length; j++)
{
if ((my_array[i] == my_array[j]) && (i != j))
{
System.out.println("Duplicate array element : "+my_array[j]);
}
}
}
}
}Result
