Dealing with primitives as objects is easier at times. Most of the objects collection store objects and not primitive types. Many utility methods are provided by wrapper classes. To get these advantages we need to use wrapper classes. As they are objects, they can be stored in any of the collection and pass this collection as parameters to the methods.

Features of the Java wrapper Classes:

- Wrapper classes convert numeric strings into numeric values.

- The way to store primitive data in an object.

- The valueOf() method is available in all wrapper classes except Character

- All wrapper classes have typeValue() method. This method returns the value of the object as its primitive type.

Set - Value is assigned to ActiveX Object from the form.

Let - Value is retried to ActiveX Object from the form.

However, new shareholders usually get to have a say in how the company is run. Despite these rights, equity is often seen as a risky choice for investors as they will lose all their money if the company doesn’t prosper. If it does well, on the other hand, they may see their stake multiply in value many times over.

Debt finance – money raised through loans – must be repaid eventually by a company, usually with interest, but lenders won’t be able to exert as much influence as shareholders over how the company does business. The debt of a reliable company is usually seen as a safe investment, but fixed repayment schedules means that there are few opportunities for large returns.
