Question

PhoneNumber

You will want to go to PhoneNumber.java and implement the following methods

• getType
• setType(String)
  Once again no need to check type, any String is allowed.
• getNumber()
  returns the raw number
• setNumber(String number)
  sets the number (10 character string, digits only). You do not need to confirm the string format that is done in another class.
• getAreaCode()
  Uses substring to get the first 3 digits of the number.
• getPrefix()
  Gets the next three digits (so 4-6) as a string, uses substring
• getLine()
  Gets the last four digits. Remember with substring, if you only put in one parameter, it gives you the remainder of the string from that point.

Additional Methods

getPrettyNumber()
Combines String.format with getAreaCode(), getPrefix() and getLine() to return a pretty formatted phone number.
The format would be as follows for 9708675309:

(970) 867-5309

render()
Uses getPrettyNumber() and getType() to build a formatted String. Like Email, the type should have 7 padding. For example:

Home:   (970) 111-5309
Office: (970) 111-1101

public class PhoneNumber {
private String type;
private String number;

/**
* The type of phone number - mobile, home, office, other
* @return the type associated with the number
*/
public String getType() {
return type;
}

/**
* sets the type of phone number
* @param type string to set it to
*/
public void setType(String type) {
this.type = type;
}

/** Gets the phone number as *rawnumbers* only **/
public String getNumber() {
return number;
}

/** Sets the phone number. I thousl be set as raw numbers 5554443333 for example, NOT (555)444-3333 **/
public void setNumber(String number) {
this.number = number;
}

/** Gets the first 3 digits, you can assume US Standard, so 10 digits **/
public String getAreaCode() {
return ""; //TODO STUDENT
}

/** Gets the second three digits. In the number (555) 444-3333, 4444 would be the prefis. Remember, phone
* numbers are stored as number strings only, so 5554443333.
* @return the prefix
*/
public String getPrefix() {
return ""; //TODO STUDENT
}

/** get the last four digits in a number (so location 6 onward) **/
public String getLine() {
return ""; //TODO STUDENT
}

/**
* Reformats a 10 digit only number, into US Standard display format, so 5554443333 becomes (555) 444-3333
* @return a US Standard formatted number
*/
public String getPrettyNumber() {
return ""; //TODO STUDENT
}

/**
* Returns a string of format type: prettyNumber - the type is 7 padded (%-7s)
* @return
*/
public String render() {
return ""; //TODO STUDENT
}

/**
* Basic constructor
* @param type the type of number
* @param number the phone number as a ten digit string
*/
public PhoneNumber(String type, String number) {
setType(type);
setNumber(number);
}

}

code:

public class PhoneNumber {
private String type;
private String number;

/**
* The type of phone number - mobile, home, office, other
* @return the type associated with the number
*/
public String getType() {
return type;
}

/**
* sets the type of phone number
* @param type string to set it to
*/
public void setType(String type) {
this.type = type;
}

/** Gets the phone number as *rawnumbers* only **/
public String getNumber() {
return number;
}

/** Sets the phone number. I thousl be set as raw numbers 5554443333 for example, NOT (555)444-3333 **/
public void setNumber(String number) {
this.number = number;
}

/** Gets the first 3 digits, you can assume US Standard, so 10 digits **/
public String getAreaCode() {
return this.number.substring(0,3);
}

/** Gets the second three digits. In the number (555) 444-3333, 4444 would be the prefis. Remember, phone
* numbers are stored as number strings only, so 5554443333.
* @return the prefix
*/
public String getPrefix() {
return this.number.substring(3,6); //TODO STUDENT
}

/** get the last four digits in a number (so location 6 onward) **/
public String getLine() {
return this.number.substring(6); //TODO STUDENT
}

/**
* Reformats a 10 digit only number, into US Standard display format, so 5554443333 becomes (555) 444-3333
* @return a US Standard formatted number
*/
public String getPrettyNumber() {
return String.format("(%s) %s-%s",getAreaCode(),getPrefix(),getLine()); //TODO STUDENT
}

/**
* Returns a string of format type: prettyNumber - the type is 7 padded (%-7s)
* @return
*/
public String render() {
return String.format("%s: %s",getType(),getPrettyNumber()); //TODO STUDENT
}

/**
* Basic constructor
* @param type the type of number
* @param number the phone number as a ten digit string
*/
public PhoneNumber(String type, String number) {
setType(type);
setNumber(number);
}

}

Sample code used to test the above class:

class Main
{
   public static void main(String[] args) {
       PhoneNumber p=new PhoneNumber("Office","9444148408");
       System.out.println(p.render());
   }
}
