Java Float class :
Java float class encapsulates a float value. It defines several constants the largest and smallest values are stored in MAX_VALUE and MIN_VALUE. The constant NaN indicates that a value is not a number. If you divide a floating – point number by zero, the result is NaN.
This class defines these constructors:
Float(float f)
Float(double d)
Float(String str)
Here, f and d are float and double types to be encapsulated in a Float object.
str is the string representation of a float value.

Output :
Object f1 = 123.5626
Object f2 = 854.32
Minimum Value of Float = 1.4E-45
Maximum Value of Float = 3.4028235E38
Byte value of Float = 123
Short value of Float = 123
Integer value of Float = 123
Double value of Float = 123.5625991821289
(f1==f2) ?= false
f1.compareTo(f2) = -1
f1 is not a number = false
