Enum Constant Summary

Enum Constants
Enum Constant and Description
`BOOLEAN_LITERAL` The token represents a boolean literal; its `Scanner.Token.value` is either 'true' or 'false'.
`C_PLUS_PLUS_STYLE_COMMENT` The token represents a C++-style comment like "`// This is a C++-style comment.`".
`C_STYLE_COMMENT` The token represents a C-style comment, like "`/* This is a C-style comment. */`", which may span multiple lines.
`CHARACTER_LITERAL` The token represents a character literal; its `Scanner.Token.value` is the text of the character literal exactly as it appears in the source code (including the single quotes around it).
`END_OF_INPUT` Indication of the 'end-of-input' condition.
`FLOATING_POINT_LITERAL` The token represents a floating-point literal; its `Scanner.Token.value` is the text of the floating-point literal exactly as it appears in the source code (e.g. "1.23", "1.23F", "1.23D", "1
`IDENTIFIER` The token represents a Java identifier.
`INTEGER_LITERAL` The token represents an integer literal; its `Scanner.Token.value` is the text of the integer literal exactly as it appears in the source code (e.g. "0", "123", "123L", "03ff", "0xffff", "0b10101010").
`KEYWORD` The token represents a Java keyword.
`NULL_LITERAL` The token represents the `null` literal; its `Scanner.Token.value` is 'null'.
`OPERATOR` The token represents an operator; its `Scanner.Token.value` is exactly the particular operator (e.g.
`STRING_LITERAL` The token represents a string literal; its `Scanner.Token.value` is the text of the string literal exactly as it appears in the source code (including the double quotes around it).
`WHITE_SPACE` The token represents "white space"; i.e. a non-empty sequence of whitespace characters.

- Enum Constant Detail
  - END_OF_INPUT
```
public static final Scanner.TokenType END_OF_INPUT
```
    Indication of the 'end-of-input' condition.
  - IDENTIFIER
```
public static final Scanner.TokenType IDENTIFIER
```
    The token represents a Java identifier.
  - KEYWORD
```
public static final Scanner.TokenType KEYWORD
```
    The token represents a Java keyword. ("true", "false" and "null" are not Java keywords, but BOOLEAN_LITERALs and NULL_LITERALs.)
  - INTEGER_LITERAL
```
public static final Scanner.TokenType INTEGER_LITERAL
```
    The token represents an integer literal; its Scanner.Token.value is the text of the integer literal exactly as it appears in the source code (e.g. "0", "123", "123L", "03ff", "0xffff", "0b10101010").
  - FLOATING_POINT_LITERAL
```
public static final Scanner.TokenType FLOATING_POINT_LITERAL
```
    The token represents a floating-point literal; its Scanner.Token.value is the text of the floating-point literal exactly as it appears in the source code (e.g. "1.23", "1.23F", "1.23D", "1.", ".1", "1E13").
  - BOOLEAN_LITERAL
```
public static final Scanner.TokenType BOOLEAN_LITERAL
```
    The token represents a boolean literal; its Scanner.Token.value is either 'true' or 'false'.
  - CHARACTER_LITERAL
```
public static final Scanner.TokenType CHARACTER_LITERAL
```
    The token represents a character literal; its Scanner.Token.value is the text of the character literal exactly as it appears in the source code (including the single quotes around it).
  - STRING_LITERAL
```
public static final Scanner.TokenType STRING_LITERAL
```
    The token represents a string literal; its Scanner.Token.value is the text of the string literal exactly as it appears in the source code (including the double quotes around it).
  - NULL_LITERAL
```
public static final Scanner.TokenType NULL_LITERAL
```
    The token represents the null literal; its Scanner.Token.value is 'null'.
  - OPERATOR
```
public static final Scanner.TokenType OPERATOR
```
    The token represents an operator; its Scanner.Token.value is exactly the particular operator (e.g. "<<<=").
  - WHITE_SPACE
```
public static final Scanner.TokenType WHITE_SPACE
```
    The token represents "white space"; i.e. a non-empty sequence of whitespace characters. Specifically, any line terminators appear exactly as in the inut stream. JLS8 3.6
  - C_PLUS_PLUS_STYLE_COMMENT
```
public static final Scanner.TokenType C_PLUS_PLUS_STYLE_COMMENT
```
    The token represents a C++-style comment like "// This is a C++-style comment.". Notice that the line terminator is not part of the comment; hence, this token is always followed by a WHITE_SPACE token (or by END_OF_INPUT).
  - C_STYLE_COMMENT
```
public static final Scanner.TokenType C_STYLE_COMMENT
```
    The token represents a C-style comment, like "/* This is a C-style comment. */", which may span multiple lines. In the latter case, the enclosed line terminators appear exactly as in the input stream.
- Method Detail
  - values
```
public static Scanner.TokenType[] values()
```
    Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
```
for (Scanner.TokenType c : Scanner.TokenType.values())
    System.out.println(c);
```
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static Scanner.TokenType valueOf(String name)
```
    Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
    
    Parameters:
    
    name - the name of the enum constant to be returned.
    
    Returns:
    
    the enum constant with the specified name
    
    Throws:
    
    IllegalArgumentException - if this enum type has no constant with the specified name
    
    NullPointerException - if the argument is null
