I would like to print out strings without duplicated words. The first int determines how many Strings I have, followed by the strings with duplications. But in my output I get an empty line at the first line and I would like to know how to get rid of this first empty line? Thank you for your time and help!
Input Example:
3
Goodbye bye bye world world world
Sam went went to to to his business
Reya is is the the best player in eye eye game
Output:
*empty line*
Goodbye bye world
Sam went to his business
Reya is the best player in eye game
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
int lines= sc.nextInt()+1;
String [] str= new String[lines];
for(int i=0;i<lines;i++) {
str[i]=sc.nextLine();
}
for(int i=0;i<lines;i++) {
String temp= str[i];
String[] strWords = temp.split("\\s+");
LinkedHashSet<String> hstr = new LinkedHashSet<String> ();
for(int j=0;j<strWords.length;j++) {
hstr.add(strWords[j]);
}
String[] strArr = new String[hstr.size()];
hstr.toArray(strArr);
for(int k=0;k<hstr.size();k++) {
System.out.printf("%s", strArr[k] + " ");
}
System.out.println();
}
sc.close();
}
