    {
 
        // Float value
        Float a = 17.47f;
 
        // wrapping the Float value
        // in the wrapper class Float
        Float b = new Float(a);
 
        // floatValue of the Float Object
        float output = b.floatValue();
 
        // prfloating the output
        System.out.println("Float value of "
                           + b + " is : " + output);
    }
}

Output: 

Float value of 17.47 is : 17.47




 

Program 2:

Java

// Float floatValue() method
 
class GFG {
    public static void main(String[] args)
    {
 
        String value = "54.1";
 
        // wrapping the Float value
        // in the wrapper class Float
        Float b = new Float(value);
 
        // floatValue of the Float Object
        float output = b.floatValue();
 
        // prfloating the output
        System.out.println("Float value of "
                           + b + " is : " + output);
