You have created the following class called Job:
public class Job {
private String role;
private long salary;
public String getRole() {
return role;
}
public void setRole(String role) {
this.role = role;
}
public long getSalary() {
return salary;
}
public void setSalary(long salary) {
this.salary = salary;
}
}
How would you use composition in a Intern class to indicate that an intern has a job and set the role to an Assistant?
a.) public class Intern {
private Job job;
public Intern() {
this.job=new Job();
job.setRole("Assistant");
}
}
b.) public class Intern {
private Job job;
public Intern() {
super();
job.setRole("Assistant");
}
}
c.) public class Intern {
public Intern() {
Job job=new Job();
job.setRole("Assistant");
}
}
d.) public class Intern extends Job {
public Intern() {
super();
setRole("Assistant");
}
}
