Explanation of Solution

 List of methods in Scanner class:

 The list of methods is described in the section “method summary” from Scanner class are as follows:

• close() method:
  • This method is used to close the scanner class and its return type is “void”.
• delimiter() method:
  • This method is used to match the delimiters and return that pattern.
• findInLine(Pattern pattern) method:
  • This method is used to search the next occurrence from specified pattern by discarding the delimiters and its return type is “String”.
• findInLine(String pattern) method:
  • This method is used to search the next occurrence from specified string by discarding the delimiters and its return type is “String”.
• findWithinHorizon(Pattern pattern, int horizon) method:
  • This method is used to search the next occurrence from specified pattern and its return type is “String”.
• findWithinHorizon(String pattern, int horizon) method:
  • This method is used to search the next occurrence from specified string and its return type is “String”.
• hasNext()method:
  • This method is used to return true when scanner has another token input and its return type is “boolean”.
• hasNext(Pattern pattern) method:
  • This method is used to return true when next token input is matched with specified pattern and its return type is “boolean”.
• hasNext(String pattern) method:
  • This method is used to return true when next token input is matched with specified string and its return type is “boolean”.
• hasNextBigDecimal() method:
  • This method is used to return true if next token input can be interpreted as BigDecimal value with help of nextBigDecimal() method and its return type is “boolean”.
