Step 2: Variables and Arithmetic

2.1: First Operation

First, given variables damage and number_of_hits, print the total damage dealt.

/** Main.java */

public class Main {

  public static void main(String[] args) {
    /** Step 1 Code goes here */

    /** Step 2.1 */
    int damage = 4; // Comment this line when using the next line
    // double damage = 2.5; // Uncomment this line to try it with a decimal
    int number_of_hits = 3;

    // TODO Print the total damage dealt
  }

}

Expect Output

12 (if using int)
7.5 (if using double)

2.2: More Operations

Next, given variables opponent_health, opponent_damage, opponent_shield, player_health, player_damage, and player_shield, calculate the damage dealt by the opponent on the player. Damage dealt is calculated as damage - shield. Store the damage dealt in a variable called damage_dealt. Subtract this damage from the player's health and print their new health to console.

/** Main.java */

public class Main {

  public static void main(String[] args) {
    /** Step 1 & 2.1 Code goes here */
    // TODO: Print a Welcome Message Here

    /** Step 2.2 */
    double player_health = 40;
    int player_damage = 10;
    int player_shield = 3;
    double opponent_health = 50;
    int opponent_damage = 8;
    int opponent_shield = 6;

    int damage_dealt = 0; // TODO: Calculate the damage dealt
    // TODO: Subtract the damage from the player's health and print it to console
  }

}

Expect Output

35.0

2.3: Integer Division

Calculate the number of hits it will take to defeat the opponent. You may NOT use any imports. Use casting and integer division.

/** Main.java */

public class Main {

  public static void main(String[] args) {
    /** Step 1, 2.1 & 2.2 Code goes here */

    /** Step 2.3 */
    // TODO: Calculate and print the number of hits needed to defeat the opponent. Do NOT use any imports.
  }

}

Expected Output

13

2.4: Update a variable

You received a powerbuff! Increase the player's damage by 30%. Then, calculate the opponent's new health if the player deals a hit.

/** Main.java */

public class Main {

  public static void main(String[] args) {
    /** Step 1, 2.1, 2.2 & 2.3 Code goes here */

    /** Step 2.4 */
    // TODO: Increase the player's damage by 30%. Only use multiplication.
    // TODO: Calculate and print the opponent's new health after the player deals a hit
  }

}

Expected Output

43.0
