Solution : Convert the original interface of a component into another interface, through an intermediate adapter object.

public interface BotLeader {
public void fireBullets();
}
Public class Bot implements BotLeader {
@Override
public void fireBullets() {
if (countBullet() < 0) { reload(); }
System.out.println(“1 bullet fired”);
bulletCount--;
}
}
public class Ralph {
public void smash() {
moveHandsUp();
moveHandsDownWithForce();
}
}
public class RalphAdapter implements BotLeader {
private ralph;
public RalphAdapter (Ralph activeRalph) {
this.ralph = activeRalph;

ralph.smash();
}

Bot soldier = new Bot();
Ralph raf = new Ralph();

System.out.println(“Commander commands fireBullets()”);
