 # Highlights of functionality
   * Parsing/formatting/validating phone numbers for all countries/regions of the world.
-  * getNumberType - gets the type of the number based on the number itself; able to distinguish Fixed-line, Mobile, Toll-free, Premium Rate, Shared Cost, VoIP and Personal Numbers  (whenever feasible).
-  * isNumberMatch - gets a confidence level on whether two numbers could be the same.
-  * getExampleNumber/getExampleNumberByType - provides valid example numbers for all countries/regions, with the option of specifying which type of example phone number is needed.
-  * isPossibleNumber - quickly guessing whether a number is a possible phonenumber by using only the length information, much faster than a full validation.
-  * isValidNumber - full validation of a phone number for a region using length and prefix information.

 # Quick Examples
 Let's say you have a string representing a phone number from Switzerland. This is how you parse/normalize it into a ` PhoneNumber ` object:
-```
+
+```java
 String swissNumberStr = "044 668 18 00"
 PhoneNumberUtil phoneUtil = PhoneNumberUtil.getInstance();
 try {
@@ -37,22 +38,22 @@ try {

 At this point, swissNumberProto contains:
-```
+```json
 {
-country_code: 41
-national_number: 446681800
+  "country_code": 41,
+  "national_number": 446681800
 }
 ```
 
 ` PhoneNumber ` is a class that is auto-generated from the phonenumber.proto with necessary modifications for efficiency. For details on the meaning of each field, refer to https://github.com/googlei18n/test/blob/master/resources/phonenumber.proto
 
 Now let us validate whether the number is valid:
-```
+```java
 boolean isValid = phoneUtil.isValidNumber(swissNumberProto); // returns true
 ```
 
 There are a few formats supported by the formatting method, as illustrated below:
-```
+```java
 // Produces "+41 44 668 18 00"
 System.out.println(phoneUtil.format(swissNumberProto, PhoneNumberFormat.INTERNATIONAL));
 // Produces "044 668 18 00"

 You could also choose to format the number in the way it is dialed from another country:
 
-```
+```java
 // Produces "011 41 44 668 1800", the number when it is dialed in the United States.
 System.out.println(phoneUtil.formatOutOfCountryCallingNumber(swissNumberProto, "US"));
 ```
 
 ### Formatting Phone Numbers 'as you type'
-```
+```java
 PhoneNumberUtil phoneUtil = PhoneNumberUtil.getInstance();
 AsYouTypeFormatter formatter = phoneUtil.getAsYouTypeFormatter("US");
 System.out.println(formatter.inputDigit('6'));  // Outputs "6"

 // Outputs "Zurich"
