屏蔽從控制檯輸入密碼，「無法解析符號‘控制檯’」

所以，當過我嘗試編譯這段代碼，我得到：屏蔽從控制檯輸入密碼，「無法解析符號‘控制檯’」

的java：找不到符號符號：類控制檯位置：級Java .lang.System

我不明白爲什麼當我啓動控制檯對象，System.console（）不能得到解決......

import java.io.Console; 
import java.util.Arrays; 
import java.util.Scanner; 


public class User { 
    Scanner input = new Scanner(System.in); 
    Console console = new System.console(); 

    private String userID, userPW, userPIN; 
    private char[] password = new char[6]; 


    public String getUserID() { 
     return userID; 
    } 

    public void setUserID(String userID) { 
     this.userID = userID; 
    } 

    public String getUserPW() { 
     return userPW; 
    } 

    public void setUserPW(String userPW) { 
     this.userPW = userPW; 
    } 

    public String getUserPIN() { 
     return userPIN; 
    } 

    public void setUserPIN(String userPIN) { 
     this.userPIN = userPIN; 
    } 

public void setUserInfo() { 
     System.out.print("Please enter your User ID : "); 
     this.setUserID(input.nextLine()); 

     System.out.print("Please enter your Password: "); 
     this.setUserPW(input.nextLine()); 

     this.password = console.readPassword("Enter password"); 
     Arrays.fill(this.password, '*'); 
    }
