Java Float Wrapper Class Example

/*
Java Float Example
This example shows how an object of Float can be declared and used.
Float is a wrapper class provided to wrap float primitive value. It has a single
field of type float.
*/
public class JavaFloatExample {
public static void main(String[] args) {
//create a Float object using one of the below given constructors
//1. Create an Float object from float primitive type
float f = 10.10f;
Float fObj1 = new Float(f);
System.out.println(fObj1);
//2. Create an Float object from double primitive type
double d = 10.10;
Float fObj2 = new Float(d);
System.out.println(fObj2);
/*
3. Create and Float object from String. Please note that this method can
throw NumberFormatException if string doesnt contain parsable number.
*/
Float fObj3 = new Float("25.34");
System.out.println(fObj3);
}
}
/*
Output of the program would be
10.1
10.1
25.34
