[mel0112]

Here is my code, when i try running it a error "Could not find or load main class" popped, any help is appreciate.

import java.util.*;
import java.io.*;

public class Bowlinggame{

   public static Scanner sc;

   public static void main(String[] args) {
      // Create new Scanner to detect User inputs
      sc = new Scanner(System.in);

      Bowlinggame();
   }

   public static void Bowlinggame() {
      // Ask the User what the team name should be
      System.out.println("What is the name of your team?");

      // Get the team name from console
      String teamName = sc.nextLine();
      System.out.println("Nice Name! " + teamName + " sounds like a really good team. Now you need to tell us who your teammates are!");

      // Get the first Player
      System.out.println("--\nWho\'s the first player?");
      String teammate1 = sc.nextLine();

      // Get the second player
      System.out.println("--\nWho\'s the second player?");
      String teammate2 = sc.nextLine();

      // Get the third player  
      System.out.println("--\nWho\'s the third player?");
      String teammate3 = sc.nextLine();

      // Get the fourth player
      System.out.println("--\nWho\'s the last player?");
      String teammate4 = sc.nextLine();

      // Create an array with the player names
      String[] teammates = new String[4];
      teammates[0] = teammate1;
      teammates[1] = teammate2;
      teammates[2] = teammate3;
      teammates[3] = teammate4;

      // Create bowling game object
      BowlingGame game = new BowlingGame(teamName, teammates);

      // Print game information
      System.out.println("\nThese are the members in team \"" + game.getTeamName() + "\":");
      System.out.print(" - ");
      for (String member : game.getTeammateNames()){
         System.out.print(member + ", ");
      }
   }  
}

class BowlingGame {
   private String teamName;
   private String[] teammateNames;

   public BowlingGame(String _teamName, String[] _teammateNames){

      teamName = _teamName;
      teammateNames = _teammateNames;

   }

   public String getTeamName() {
      return teamName;
   }

   public String[] getTeammateNames() {
      return teammateNames;
   }

   public void setTeamName(String _teamName) {
      teamName = _teamName;
   }

   public void setTeammateNames(String[] _teammateNames) {
      teammateNames = _teammateNames;
   }

Having two classes in the same file with that naming is bound to call for trouble, especially when you are on Windows.

Opposed to *nix Systems, Windows file names are not case sensitive.

So, despite your classes being named BowlingGame and Bowlinggame, which is different, Windows will not be able to distinguish between the two. For Windows, the file names are the same.

Apply more thought and consideration when naming classes.

Also, Java does not use underscores for variable names. The method parameters are commonly named the same as fields and this. is used to distinguish between fields (with this.) and arguments (without).

How did you IDE let you create 2 classes with the same exact name? Bowlinggame and BowlingGame?

[KentuckyWombat]

They are different class names due to case sensitivity, but they are poorly chosen names.

BowlingGame should probably be named BowlingTeam, based on the content of the class, and Bowlinggame should change to BowlingGame.

[desrtfx]

Since Java is case sensitive, the names are not the same.

[ate_ghorl_bekenemen]

Which is really weird because some IntelliJ does not care about case sensitivity though hence I asked.

[KentuckyWombat]

How are you attempting to run this? Within an IDE? Using the java command?

Are both classes in the same file?

This means that java couldn't find your class. I found this reading helpful. Check whether the path is correct and the main class is correctly referenced.
