How to convert from float to bigDecimal in java?

This is upto my knowledge :

   public static BigDecimal floatToBigDecimal(Float a){


    if(a == null || a.isInfinite() || a.isNaN()){
        return BigDecimal.ZERO;
    }
    try{
        return BigDecimal.valueOf(a);

    }catch(Exception e){
        return BigDecimal.ZERO;
    }

}

*Note:This is generally the preferred way to convert a double (or float) into a BigDecimal, as the value returned is equal to that resulting from constructing a BigDecimal from the result of using Double.toString(double).

public static BigDecimal valueOf(double val)

Parameters:
val - double to convert to a BigDecimal.
Returns:
a BigDecimal whose value is equal to or approximately equal to the value of val.
Throws:
NumberFormatException - if val is infinite or NaN.
Since:
1.5

I have checked whether Infinite or Not a Number, so that there is less chances of NumberFormatException
