Question

I m developing a simple board game in Java, but I m having some difficulties when trying to instantiate the classes I implemented (Carta, Jogador, and Tabuleiro). When attempting to compile and execute the program, it seems to be unable to find the classes, and I m getting errors like "Tabuleiro cannot be resolved to a type," for example (the same with Jogador and Carta).

Tabuleiro 班级:

Tabuleiro:

package main;

import java.util.ArrayList;
import java.util.List;

public class Tabuleiro {
    public List<List<Carta>> lines;

    public Tabuleiro() {
        this.lines = new ArrayList<>();
        for (int i = 0; i < 5; i++) {
            lines.add(new ArrayList<>());
        }
    }
}

Main:

package main;

import java.util.ArrayList;
import java.util.Collections;
import java.util.List;
import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);

        // Board creation
        Tabuleiro tabuleiro = new Tabuleiro();

我试图以这种方式(只有塔图莱罗人才有这种例子),但我会发现所有班级都存在上述错误,而所有班级都属于同一名录。

从屏幕上看,只要档案名称有<密码>。 Java的延伸,而不是.java,因此没有被适当承认为 Java源档案。重新命名案卷时,应作小事。

作为附带说明, Java在命名公约方面非常严格,例如,您的档案名称必须与公共类别名称相符,名录结构必须贴上包装名称。详见。
