This part of the code captures input and converts string values to relavent primitive types,using Wrapper classes. Here is the code: String name = JOptionPane.showInputDialog( null, "Enter your name here : " ); String inputint = JOptionPane.showInputDialog( null, "Enter your age here : " ); int age = Integer.parseInt( inputint ); String inputsal = JOptionPane.showInputDialog( null, "Enter your salary here : " ); float sal = Float.parseFloat( inputsal ); When I compile it gives error at last line which parses float from the string. Why can't we use the parseFloat similar to parseInt? Thanks..

I don't get any error using jdk 1.3 beta on Windows 98. What error exactly are you getting?

I am working on an IDE, JDeveloper, which uses JDK 1.2, and it gives an error as : method parseFloat(java.lang.String)not found in class java.lang.Float

I get an error when I try the same thing. Do you have to import a special package for these? If its just my JDK, where can I download the lastest one? Thanks -Chris

I downloaded the JDK 1.3 from that link and set my compiler (RealJ) to know where it is on my computer, but I still get the following errors:
The problem is obviously in these two strings:
Does anybody know what i'm doing wrong?

method names always start with a lowercase letter. Look at the JavaDoc for the API libraries. It documents all the methods in all the classes. the method you want is parseInt(), not ParseInt(). Java is case-sensitive.

Hand on...I just tried to recompile then I got another error (GRR!). Here it is
Another great source to assist along the path of learning Java is Sun's Java Tutorial. ---- Hint: Perhaps what you wanted to do before was use one of the String.valueOf methods. Good Luck, -Dirk Schreckmann [ March 11, 2002: Message edited by: Dirk Schreckmann ]

Technically speaking, at what point was this thread hijacked? Was it before or after this post? -Dirk Schreckmann Newest member of Hijackers Anonymous [ March 11, 2002: Message edited by: Dirk Schreckmann ]

This thread wasn't hijacked at all. He was having small problems that looking at a tutorial and/or the API would solve. That is until you brought up hijacking threads.

Thanks for the clarification Paul. I was curious as to just how sensitive the Police were to hijacking. Your position seems perfectly reasonable. [ March 11, 2002: Message edited by: Dirk Schreckmann ]

If you look up the API documentation for String, you'll see there is no such method in the String class called "parseString()"; If you're trying to create a String object from an int value, you want to use String.valueOf(int value); If you want to parse a String value and return an int, you would use Integer.parseString(String intString); Again, you need to become familiar with the JavaDoc (documentation for the java API).
