Error with convert to Float

[cachi]

Hi, Please have a look in this small program and the error that compiler returns

Code:

package Package;

/**
*
* @author cachi
*/
public class book {
String title;
String code;
String last;
String isbn;
Integer quantity;
Float price;
/** Creates a new instance of book */
public book(String mytitle,String mycode,String mylast) {
title=mytitle;mycode=code;mylast=last;
}
public book(String mytitle,String mycode,String mylast,String myisbn,Integer myquantity,Float myprice) {
title=mytitle;code=mycode;last=mylast;isbn=myisbn;quantity=myquantity;price=myprice;
}
public void setTitle(String mytitle) {title=mytitle;}
public void setCode(String mycode) {code=mycode;}
public void setLast(String mylast) {last=mylast;}
public void setIsbn(String myisbn) {isbn=myisbn;}
public void setQuantity(Integer myquantity) {quantity=myquantity;}
public void setPrice(Float myprice) {price=myprice;}

public String getTitle(){return title;}
public String getCode(){return code;}
public String getLast(){return last;}
public String getIsbn(){return isbn;}
public Integer getQuantity(){return quantity;}
public Float getPrice(){return price;}
public Float getValue(Integer discount){return (float)(discount*price);} //Find out what to return here
public void showBook (){} //How i must show the book?
}

Code:

public Float getValue(Integer discount){return (float)(discount*price);} //Find out what to return here
^
Package/book.java [40:1] incompatible types
found : float
required: java.lang.Float
public Float getValue(Integer discount){return (float)(discount*price);} //Find out what to return here
^
2 errors

Thanks.

I haven't tried ur code since i don't know what ur main program call upon the code, but from the error messages, it seems that the auto-boxing from float into Float wrapper class didn't work well
Maybe u could do this way

Code:

public Float getValue(Integer discount){return (Float)(discount*price);} //Find out what to return here

Btw, why must u use the Float wrapper instead of the primitive float?
It would be less memory consuming if u just use the primitives, u didn't use the toString() or any other wrapper method in ur code after all

I suggest using primitives for this one
