我在Eclipse中为一个简单的二十一点游戏编写了一个程序，它没有任何问题。但是，当我尝试在我的pico编辑器中使用javac进行编译时，它不会编译。为什么Eclipse没有说出编译错误的位置？代码如下。
import java.util.Scanner;
import java.util.Random;
public class Blackjack {
public static void main(String args[])
{
Scanner keyboard = new Scanner(System.in);
Random randomGenerator = new Random();
int nextCard;
boolean keepPlaying = true;
boolean playAgain = true;
char hit;
int DECK_MAX = 10;
//This is the main loop to play the entire game
while (playAgain == true)
{
int userCard1 = randomGenerator.nextInt(DECK_MAX) + 1;
int userCard2 = randomGenerator.nextInt(DECK_MAX) + 1;
int userTotal = userCard1 + userCard2;
int dealerCard1 = randomGenerator.nextInt(DECK_MAX) + 1;
int dealerCard2 = randomGenerator.nextInt(DECK_MAX) + 1;
int dealerTotal = dealerCard1 + dealerCard2;
//This deals the first two cards to the user, and prints the total
System.out.println("Welcome to the CCSF Casino! Lets play...");
System.out.println("Your first cards are " + userCard1 + " and " + userCard2);
System.out.println("You have a total of " + userTotal);
//The following checks three scenarios that can end the game on the first deal
if (userTotal == 21 && dealerTotal == 21)
{
System.out.println("Both you and the dealer have 21. It's a push.");
keepPlaying = false;
}
if (userTotal != 21 && dealerTotal == 21)
{
System.out.println("The dealer was dealt 21. You lose.");
keepPlaying = false;
}
if (userTotal == 21 && dealerTotal != 21)
{
System.out.println("You have 21. You win!");
keepPlaying = false;
}
//The following checks if the game should continue to user interaction phase, and takes user input if so
if (keepPlaying == true)
{
System.out.println("The dealer is showing " + dealerCard1 + " with one card face down.");
//The following asks the user if they want to keep hitting as long as their total is less than 21
while (userTotal < 21)
{
System.out.println("Would you like another card(y/n)?");
hit = keyboard.next().charAt(0);
if (hit == 'y')
{
nextCard = randomGenerator.nextInt(DECK_MAX) + 1;
userTotal += nextCard;
System.out.println("You were dealt a " + nextCard + " for a total of " + userTotal);
if(userTotal > 21)
{
System.out.println("You bust and lose. Sorry...");
keepPlaying = false;
break;
}
}
else
break;
}
}
//The following checks if the game should continue to the dealer interaction phase. If so, it hits until dealer has > 17
if (keepPlaying == true)
{
System.out.println("The dealer's current total is " + dealerTotal);
while (dealerTotal < 17)
{
nextCard = randomGenerator.nextInt(DECK_MAX) + 1;
dealerTotal += nextCard;
System.out.println("Dealer has been dealt a " + nextCard + " for a total of " + dealerTotal);
if (dealerTotal > 21)
{
System.out.println("The dealer busts. You win!");
keepPlaying = false;
break;
}
}
}
//The following checks if the game should continue into the comparison phase. If so, it determines whether the dealer of user win
if (keepPlaying == true)
{
if (userTotal > dealerTotal)
System.out.println("You win! You had " + userTotal + " and dealer only had " + dealerTotal);
if (userTotal < dealerTotal)
System.out.println("You lose...You only had " + userTotal + " and dealer had " + dealerTotal);
if (userTotal == dealerTotal)
System.out.println("It's a push!");
}
System.out.println("Would you like to play again(y/n)?");
if (keyboard.next().charAt(0) == 'y')
{ playAgain = true;
keepPlaying = true;
}
else
{
System.out.println("Don't let the door hit you on the way out!");
break;
}
}
}
}
这是我从javac取回的内容

Sorry everybody, but the issue ended up being related to me not correctly saving the file name on the ssh I'm using for the javac. Didn't mean to waste your time, and I appreciate the input. Will make sure to review much more closely in the future before bringing here.
