Hi guys here is my java code, when I run it with eclipse I get it correctly, however when run with Dr.Java (which is what the teachers use to correct) I get this error. Yes I'm a noob, why am I using eclipse then? simply because the youtube tutorial guys use it. The code is supposed to be ran through the interaction pane by typing in 4 integer values.

Here is my code

public class Test2 {
public static void main(String[] args){
int A = Integer.parseInt(args[0]);
int Q = Integer.parseInt(args[1]);
int M = Integer.parseInt(args[2]);
int F = Integer.parseInt(args[3]);
}
public static int finalGrade(int A, int Q, int M, int F){
int sum = A + Q + M + F;
int alternative = A + Q + (F*3/2);
if(F/2 > M){
return alternative;
}
else{
return sum;
}
}
}

4 errors found:
