因此,当我尝试编译此代码时,我得到:
java:找不到符号 符号:类控制台 location:类java.lang.System
我不明白为什么当我启动控制台对象时,System.console()无法解析...
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, '*');
}

不是
Console console = new System.console();
应该是
Console console = System.console();

您正在尝试使用System类访问控制台,其中console()方法是静态的,因此无需在System.console()前放置新关键字,只需删除新关键字。
