Hi,
This is my first thread,iam using Jcreator IDE for running java programs
I got the following error when i executed the program
/*number1=Integer.parseInteger(in.readLine());
number2=Integer.parseInteger(in.readLine());
res=Integer.parseInteger(in.readLine());
*/
Error: D:\jp\new6.java:13: cannot find symbol
symbol : method parseInteger(java.lang.String)
location: class java.lang.Integer
number1=Integer.parseInteger(in.readLine());
^
D:\jp\new6.java:14: cannot find symbol

I got the following error when i executed the program

It looks like a compiler error, not an execution time error.
The compiler can't find the parseInteger(java.lang.String) method in the class java.lang.Integer.

Read the API doc for the Integer class to be sure you are spelling the method name correctly.

{
public static void main(String args[])
{
DataInputStream in =new DataInputStream(System.in);
int number1;
int number2;
int res;
System.out.println("Enter the two values for Addition");
number1=Integer.parseInt(in.readLine());
number2=Integer.parseInt(in.readLine());
res=Integer.parseInt(in.readLine());
res=number1+number2;
System.out.println("The result is : " + res);

}
}

We aren't here to fix your code, instead we give you the information necessary to fixing the problem(links to API docs, or explaining why something isn't working), provide us with the errors. Not everyone is willing/able to compile and run the code.

Read this link(mainly what it says about readLine()): http://download.oracle.com/javase/6/...putStream.html

If you are simply reading from the console I suggest you use a scanner instead: http://download.oracle.com/javase/6/...l/Scanner.html

And if you want to work with the streams instead, check this out: http://download.oracle.com/javase/tu.../essential/io/

Hi,I get u that u r not there to fix our code,.
I posted the errors now
suggest a solution
Thanks in advance

java.io.IOException; must be caught

The statement that is referred to throws an IOException. You should put that code inside of a try{}catch(){} block that catches that exception.

D:\jp>java new6
