Answer 1

other file for storage data is:
//StoringData class
class StoringData{
private String name;
private String password;
private String phone;
private String allthetext;
private int currentsalary;
private int desiredsalary;
public StoringData()
  name = null;
  password = null;
  phone = null;
  allthetext = null;
  currentsalary = 0;
  desiredsalary = 0;
public StoringData(String n,String pw, String p,String a, int c, int d)
  name = n;
  password = pw;
  phone = p;
  currentsalary = c;
  desiredsalary = d;
  allthetext = a;
public String getName1()
  return name;
public String getPassword1()
  return password;
public String getPhone1()
  return phone;
public String getAllTheText1()
     return allthetext;
public int getCurrentSalary1()
  return currentsalary;
public int getdesiredsalary1()
  return desiredsalary;
}
