Task

Now, let's tackle a simple task where you need to correctly fill in the primitive data types in the blanks:

java

Main.java

  1. 1. You can peek at the list of primitive data types.
  2. 2. Pay attention to the letter f. Only one primitive data type is marked with f.

package com.example;

public class Main {
    public static void main(String[] args) {
        byte myNum = 14;
        double myFractional = 14.928;
        short myBiggerNum = -710;
        char myLetter = 'B';
        boolean myBool = true;
        float myWho = 1.74f;
        System.out.println("It's working, well done!");
    }
}

Everything was clear?
