20.9.6

public Float(float value)

This constructor initializes a newly created

Float

 object so that it represents the

primitive value that is the argument.

20.9.7

public Float(double value)

This constructor initializes a newly created

Float

 object so that it represents the

result of narrowing ( 5.1.3) the argument from type

double

 to type

float

.

20.9.8

public Float(String s) throws NumberFormatException

This constructor initializes a newly created

Float

 object so that it represents the

floating point value of type

float

 represented by the string. The string is con 

verted to a

float

 value in exactly the manner used by the

valueOf

 method

( 20.9.17).

20.9.9

public String toString()

The primitive

float

 value represented by this

Float

 object is converted to a

string exactly as if by the method
