    Enumeration

  • 2

    Enum: Returns the name of the calling constant object

    toString()

  • 3

    Enum: Returns an integer that represents the constant’s position in the list of constants; the first position is 0

    ordinal()

  • 4

    Enum: Returns true if its argument is equal to the calling object’s valu

    equals()

  • 5

    Enum: Returns a negative integer if the calling object’s ordinal value is less than that of the argument, 0 if they are the same, and a positive integer if the calling object’s ordinal value is greater than that of the argument

    Repetition Operator

  • 23

    This class in the java.util.regex package stores the format of a regular expression.

    Pattern

  • 24

    Matcher

  • 26

  • 27

    This method in "match" scans the input sequence looking for the next subsequence that matches the pattern. I

    find()

  • 28

    method is used to replace all the occurrences of the defined regular expression found in the string with another string

    replaceAll()

  • 29

    method compares one (1) string to another by comparing a single argument.

    equals()

  • 30

    method allows you to determine what the string should match against and allows you to specify multiple values.

    matches()

  • 31

    Pattern p = Pattern.compile("[0-9]"); String str = "Password"; Matcher match = p.matcher(str); System.out.println(match.find());

    returns false

  • 32
