布尔函数返回false值无论如何

Question

我正在为学校作业创建一个简单的程序，该程序创建一个非常基本的用户帐户，并将用户输入的密码与帐户密码进行比较。无论我将什么值传递给checkPassword函数，它总是返回false值。

到目前为止，我已经按照您在此处看到的功能编写了该函数，并将其分解为if else语句并根据该值返回了一个值。

我已经从main方法和checkPassword方法中显示了要与屏幕进行比较的值，以便我知道这些值是匹配的。

package firstAssignment;

public class UserAccount {

    // Fields
    private String username;
    private String password;
    private boolean active;

    // Constructors
    public UserAccount() {
        this.active = true;
    }

    public UserAccount(String username, String password) {
        this.username = username;
        this.password = password;
        this.active = true;
    }

    // Getters and setters

    public String getUsername() {
        return username;
    }

    public void setUsername(String username) {
        this.username = username;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public boolean isActive() {
        return active;
    }

    public void setActive(boolean active) {
        this.active = active;
    }

    // Methods

    public boolean checkPassword(String password) {
        return (this.password == password);
    }

    public void deactivateAccount() {
        this.active = false;
    }

    @Override
    public String toString() {
        return this.username;
    }

    @Override
    public int hashCode() {
        final int prime = 31;
        int result = 1;
        result = prime * result + ((username == null) ? 0 : username.hashCode());
        return result;
    }

    @Override
    public boolean equals(Object obj) {
        if (this == obj)
            return true;
        if (obj == null)
            return false;
        if (getClass() != obj.getClass())
            return false;
        UserAccount other = (UserAccount) obj;
        if (username == null) {
            if (other.username != null)
                return false;
        } else if (!username.equals(other.username))
            return false;
        return true;
    }



}

无论我提供什么值，它总是返回false值。
