1. To make a class executable, it must contain the following method:

public static void main (String[] parameters) {}

2. What is "CURRENT"? If you mean "current" you should write it.

3. You should use "System.out" instead of "system.out"

4. What class is EasyIn? This is not an error, I just don't know the class.

class somprog
{
public static void main (String args[])
{
final int current;
int age;
System.out.println("How Old Are You This Year?");
age = EasyIn.getInt();
System.out.println("I think you were born in" + current-age);

EasyIn.pause("press <Enter> to quit");


}
}

It still has one error:

variable current might not have been initialized
System.out.println("I think you were born in" + (current - age));

Well you just need to do the right importation needed on your cod
start with import java.io.*;
and there's a throws IOEXception to do right here<public static void main(String[] arg) throws IOException{
then your code here }
what's the Easyin thing?

For your 'current' problem:

Just initialize the variable.

final int current = 2004;

1> The signature of the main method is incorrect is should like this
public static void main(String[] arg)
2> The variable 'CURRENT' you used is in all small letter where you declared it but you are using all caps in a System.out.println statement that is incorrect.
3> 'S' of System.out.println must be a capital letter.
4> 'L' of System.out.println must be a small 'l'.
Java is case senstive.
5> It will be better if you provide the code for class EasyIn

check this out :
import java.util.*;
import java.io.*;
class someprog{
public static void main(String[] lalama)throws IOException{
Calendar now=Calendar.getInstance();
int current=now.get(Calendar.YEAR);
int age=Integer.pasreInt();
int y=current-age;
System.out.println("you were borne :"+y);
}
}

Argument is missing in main method

Ex: public static void main (String[] args)
