[問題] 取不到 System.console() 問題
import java.io.Console;
public class consoledemo {
public static void main(String[] args) {
System.out.print("請輸入名稱：");
Console console = System.console();
String name = console.readLine();
System.out.println("您輸入的名稱…" + name);
}
}
這是一個練習的程式碼
用命令提示字元run一切正常
可是用netbeans來run卻說有error
請問是出了甚麼問題嗎??
--------
錯誤碼：
run:
Exception in thread "main" java.lang.NullPointerException
請輸入名稱： at concoledemo.main(concoledemo.java:15)
Java Result: 1
