Hi,
Can anybody help me to sort this out please.

class..
{
Object p=pList.getCap(); //either this
String s=pList.getCap(); //or this

//here I need to cast the Object or String (any will do) into double
//to send it as an argument to coldDrinks(int, double) method
sDB.coldDrinks(++coldDrinkNo,softDrinkPrice);
}


other class
{
Object/String getCap()
{
}
}


other class
{
coldDrinks(int, double)
{..}
}


Thanks in advance.

Well, the question is, what does getCap() actually return? Is it a String? If so, look at the static parseDouble() method in the java.lang.Double class.

It is sorta covered in the JavaRanch Style Guide.
