Question

How would I search throught the arraylist jobs to find internship type? Please see the below code (arraylist class and tester)

public class Company
{
//instance variables
private String coName, contact, coEmail, jobTitle, jobType, paid, semester;
  
//constructor method
public Company(){}

//parameterized constructor
public Company (String n, String c, String e, String j, String t, String p, String s)
{coName=n;
contact=c;
coEmail=e;
jobTitle=j;
jobType=t;
paid=p;
semester=s;
}

//set methods
public void setConame(String n)
{
coName=n;
}
public void setContact(String c)
{
contact=c;
}
public void setCoemail(String e)
{
coEmail=e;
}
public void setJobtitle(String j)
{
jobTitle=j;
}
public void setJobtype(String t)
{
jobType=t;
}
public void setPaid(String p)
{
paid=p;
}
public void setSemester(String s)
{
semester=s;
}
//access method
public String getConame()
   {
   return coName;
}
public String getContact()
   {
return contact;
}
public String getCoemail()
   {
return coEmail;
}
public String getJobtitle()
   {
return jobTitle;
}
public String getJobtype()
   {
return jobType;
}
public String getPaid()
   {
return paid;
}
public String getSemester()
   {
return semester;
}

//display
public String toString()
   {
   //String coprt=(coName+" "+jobTitle+" "+jobType+" "+paid+" "+semester);
   //return coprt;
  
   String s="" + coName + " offers internships for " + jobType;
   return s;
   }
}

/*
1- populate arraylists (if empty ?? -- how is array data retained?)
-- private variables
2- user interface options: 1) display all companies offering...2) display all students wanting...
   3)search by internship type, company, student then generate reports
3- methods to enable add / edit / remove records in arraylist (if/else) => how/from where to call these methods?
-- companies, students, internships, ... all data elements?
-- is there simple way to SEARCH? => API Collections
-- RESEARCH: look up list

** REMEMBER CLEAN UP OUTPUT FORMAT **
