[pbl]

no "." after the import statement

import java.io.*;
import java.text.NumberFormat;
import java.lang.Math;

[g00se]

import.java.io.*;

should be

import java.io.*;

[mostyfriedman]

there's no '.' after import

import java.io.*;
import java.text.NumberFormat;

^
operator == cannot be applied to java.lang.String,char
} while (reply=='Y' || reply=='y');

nextGuessNumber = tempNum.intvalue;

[pbl]

you cannot compare String with ==
you'll have to use the String equals method or equalsIgnorecase

String x;
String y;

if(x.equalsIgnoreCase(y))
.....

Thank you and i have changed as below and the error for this solve


But still having error. Cannot resolve symbol. I have import the needed items at the first line but still having errors below


--------------------Configuration: <Default>--------------------
cannot resolve symbol
symbol : method readline ()
location: class java.io.BufferedReader
String reply = input.readline();

[pbl]

the method in Buffered Reader id readLine() not readline();

didn't know that NumberFormat had a getInstance() method ... if it is the case you get an instance of an already existing NumberFormat() so there in no "new" there

NumberFormat numFormat = NumberFormat.getInstance();

I presume that intvalue should be intValue

[javabeginner1]

Anybody willing to help me sort out this errors

[pbl]

answered one reply before

[mostyfriedman]

pbl beat me and mentioned the errors , your code should work nicely now

[javabeginner1]

Yes Pbl. You have been very helpful.

You are right on the readline => readLine, no new in NumberFormat() and intvalue => intValue.

But i still have one error


--------------------Configuration: <Default>--------------------
cannot resolve symbol
symbol : variable intValue
location: class java.lang.Number
nextGuessNumber = tempNum.intValue;
^
1 error

Process completed.

Do i need to include something like import java.lang.Number (not sure on this).


The NumberFormat and getInstance() method i refferd to a book by James M. Slack (Programming and Problem Solving with JAVA), 1st edition, ISBN No. 0534374867.


Page 353





pbl and mostyfriedman

really appreciate your feedback

intValue(); add brackets because this is a method

and also you dont have to import any classes from the lang package because it is implicitly imported by the compiler in every java program you write, this should save you some typing in the future...also i would recommend this book for you..java how to program 6th edition, its a great book with many examples, check it out

Thanks. Still working on it and will revert back if i encounter any new problems.

Thanks once again Pbl
