Minor problem

Question

I havn't got my previous work to look at so i am completely stuck on how to do this general formatting to get rid of that damn static context error.
Here is the basic code layout
public static void main(String [ ] args){
System.out.println("Main menu");
   switch(choice){
   case 1:
         counter++;
         secondMenu();
public void secondMenu(){
System.out.println("Second menu");
}I know its due to counter++ but how can i do some calculations still?

Answer 1

You can only (directly) call static methods inside other static methods:
class X {
  static void a() {
    b(); 
  static void b() {
} However, if b() is NOT static, you will have to make an instance of X and then call b() on that instance:
class X {
  static void a() {
    X instance = new X();
    instance.b(); 
  void b() {
I recommend you to read this tutorial from Sun Understanding Instance and Class Members :
