Java Examples - Find Duplicate Elements in an Array
Java ExamplesThe following example demonstrates how to find duplicate elements in Java:
Main.java file
public class MainClass {
public static void main(String[] args)
{
int[] my_array = {1, 2, 5, 5, 6, 6, 7, 2, 9, 2};
findDupicateInArray(my_array);
}
public static void findDupicateInArray(int[] a) {
int count=0;
for(int j=0;j<a.length;j++) {
for(int k =j+1;k<a.length;k++) {
if(a[j]==a[k]) {
count++;
}
}
if(count==1)
System.out.println( "Duplicate elements:" + a[j] );
count = 0;
}
}
}
The output of running the above code is:
