Shown below is the source code for printing duplicate character or string in a sentence. Simply pass in the char/string as a command line argument i.e. args
~~~~~~~~~~~~~~~~~~~~~~~~~
import java.util.*;
import static java.lang.System.out;
public class Duplicate
{
public static void main(String... args)
{
Set<String> s = new HashSet<String>();
for(String ss : args)
if (!s.add(ss))
{
out.println("Duplicate Found:" + ss);
}
}
}
