JAVA

public classHeMan extends Skeletor {

public void attack() {

super.attack();

System.out.print("heman-A ");

}

public String toString() {

return "heman!";

}

public classSheRa {

public void attack() {

System.out.print("shera-A ");

}

public void train() {

System.out.print("shera-T ");

}

public String toString() {

return "shera!";

}

public classBattleCat extends HeMan {

public void attack() {

System.out.print("battlecat-A ");

}

public void train() {

attack();

System.out.print("battlecat-T ");

}

public classSkeletor extends SheRa {

public void train() {

System.out.print("skeletor-T ");

attack();

}

Given the classes above, what output is produced by the following code?

SheRa[] superheros = {new Skeletor(),new HeMan(),new SheRa(),new BattleCat() };

for (int i = 0; i < superheros.length;="" i++)="">

superheros[i].train();

System.out.println();

superheros[i].attack();

System.out.println();

System.out.println(superheros[i]);

System.out.println();

}
