Answer:
import java.util.*;
public class MyClass {
public static void main(String args[]) {
Scanner input = new Scanner(System.in);
System.out.print("Input a word: ");
String userinput = input.nextLine();
for(int i =0;i<userinput.length();i+=2) {
System.out.print(userinput.charAt(i));
}
}
}
Explanation:
This line prompts user for input
System.out.print("Input a word: ");
This declares a string variable named userinput and also gets input from the user
String userinput = input.nextLine();
The following iterates through every other character of userinput from the first using iteration variable i and i is incremented by 2
for(int i =0;i<userinput.length();i+=2) {
This prints characters at i-th position
System.out.print(userinput.charAt(i));
Answer:
find()
Explanation:
When dealing with MongoDB the method that needs to be used in this scenario would be the find() method. This method basically returns all of the records that exist in the collection on which it is called, if no parameter is passed. If you pass a parameter/expression then only the records that match completely the expression will be returned to the user, otherwise nothing is returned. For example, on a database (db) we would call the following
db.find() ... This will return all records
db.find({specific}) ... This will return only the records that match specific.
