Using Static Method To Convert A String To Integer Object - Compiler Error

I am using a static method to convert a string to an Integer object. Next using a instance method to convert Integer object to an int.

Compiler is giving me two "cannot find symbol" errors:

One pointing to the dot operator between "Integer.valueOf(s)"

The other pointing to the dot operator between "obj.intValue()"

I have latest JDK installed: jdk-7u51-windows-x64.exe

Looks like JCL installed correctly with rt.jar file located in "lib" directory under "Program Files"

Following is source code:

Java Code:

public class StringToInt
{
public static void main (String args [])
{
String s = "125";
Integer obj = Integer.valueOf(s);
int i = obj.intValue();
i += 10;
System.out.println(i);
}
} mh_sh_highlight_all('java');
