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?
