无法编译java代码
我在Eclipse中为一个简单的21点游戏编写了一个程序，它运行时没有任何问题。然而，当我尝试在pico编辑器中使用javac编译时，它不会编译。为什么Eclipse不说编译错误在哪里？代码如下无法编译java代码,java,compiler-errors,Java,Compiler Errors,我在Eclipse中为一个简单的21点游戏编写了一个程序，它运行时没有任何问题。然而，当我尝试在pico编辑器中使用javac编译时，它不会编译。为什么Eclipse不说编译错误在哪里？代码如下 import java.util.Scanner; import java.util.Random; public class Blackjack { public static void main(String args[]) { Scanner keybo

对不起，大家，但问题最终与我没有正确地将文件名保存在我用于javac的ssh上有关。我不是想浪费你的时间，我很感激你的意见。在带到这里之前，请确保在将来更仔细地查看。javac说了什么？换句话说，请发布完整的编译器错误消息，并指出哪些行导致了问题。userTotal和DealTotal都不会是21。最多20个。第一条错误消息显示用户的总数。我看不到代码中的文本。请重试。您正在编译的代码可能不是您在此处显示的代码。
