Expert Solution

Here is the solution to your question. I tried my best to solve your doubt, however, if you find it is not as good as expected by you. Please do write your further doubts regarding this question in the comment section, I will try to resolve your doubts regarding the submitted solution as soon as possible.

Please give proper indentation as shown in the screenshot

If you think, the solution provided by me is helpful to you please do an upvote.

Your code looks fine and it will get compiled if you change some code

1) In ToString() method of Robot.java , remove passed arguments of getCapabilities() as it does not require any parameter.

2) Simillarly in ToString() method of MovieRobot.java , remove passed arguments of getCapabilities() as it does not require any parameter.

Rest of the code is fine. Below is the code with proper changes that needs to be applied

class Robot {
  int serialNumber;
  boolean flies,
  autonomous,
  teleoperated;
  public void setCapabilities(int serialNumber, boolean flies, boolean autonomous, boolean teleoperated) {
    this.serialNumber = serialNumber;
    this.flies = flies;
    this.autonomous = autonomous;
    this.teleoperated = teleoperated;
  }
  public int getSerialNumber() {
    return this.serialNumber;
  }
  public boolean canFly() {
    return this.flies;
  }
  public boolean isAutonomous() {
    return this.autonomous;
  }
  public boolean isTeleoperated() {
    return this.teleoperated;
  }
  public String getCapabilities() {
    StringBuilder str = new StringBuilder();
    if (this.flies) {
      str.append("canFly");
      str.append(" ");
    }
    if (this.autonomous) {
      str.append("autonomous");
      str.append(" ");
    }
    if (this.teleoperated) {
      str.append("teleoperated");
    }
    return str.toString();
  }
  public String toString() {
    return "ID: " + this.serialNumber + ", Capabilities: " + getCapabilities();
  }
}

//Drone class
