How we can check that current string is already inputted or not

general

1

Given n, which is the number of strings taken as input. For each input use have to print “YES” or “NO” whether the current string is already present or not.

Input:
5
Geeks
Hello
Great
Geeks
Hello
Output:

No
No
No
Yes
Yes

2

Maintain a set of strings and for every input string, check if the count of that particular string in the set is 0 or not. If it is 0, it means the string is unique, else it has been inputted before.

public class StringArray {
public static void main(String agrs[])
{
int c=0,j=0;
String a[] = {“Geeks”,“Hello”,“Great”,“Geeks”,“Hello”};

		 for(int i=0;i<5;i++)
		 {
			 for(j=0;j<i;j++)
			 {
			 c=0;
			 if(a[i]==a[j])
			 {
				 c++;
				 break;
			 }
			}
			 if(c==0)
				   System.out.println("no");
				 else
				 System.out.println("yes");
					 
		 }
}
