Question

基本上这是我想要实现的行动：

Please type your new password:
1234
Please enter your password:
1234
This password is correct.
(And Vice Versa)

每次我启动或编辑此代码时，我得到的都是“此密码不正确” P.S：我对这一切都不熟悉！这是我的主要课程：

package PasswordValidation;
import java.util.Scanner;

public class Main {
public static void main(String[] args){
    Scanner kbrdIn = new Scanner(System.in);

    PasswordDB pwdObject = new PasswordDB();
        System.out.println("Please type your new password: ");

    String userPwd;
        userPwd = kbrdIn.nextLine();

    pwdObject.setPwd(userPwd);
    pwdObject.checkPwd();

        kbrdIn.close();
    }
}

这是我的PasswordDB.java类：

package PasswordValidation;
import java.util.Scanner;

class PasswordDB {

Scanner pwdInput = new Scanner(System.in);

private String passWord;

public void setPwd(String name){
    passWord = name;
}   

public String getPwd(){
    return passWord;
}
public final void checkPwd(){

    System.out.println("Please enter the password: ");
        String pwdIn = pwdInput.nextLine();


if(pwdIn == passWord){

    System.out.println("Your password is correct.");
}else{

    System.out.println("Your password is incorrect.");

    }
  }
}

在Java中，您应该从不使用 cc -O3 -fexceptions -fPIC -DNBLAS -LD:/SuiteSparseBuild/UMFPACK/Lib -lsuitesparseconfig -lrt -I../Include -I../../AMD/Include -I../../SuiteSparse_config -c -DBUILD_DLL umfsolver.c cc1: warning: fPIC ignored for target (all code is position independent) cc -O3 -fexceptions -fPIC -DNBLAS -LD:/SuiteSparseBuild/UMFPACK/Lib -lsuitesparseconfig -lrt -I../Include -I../../AMD/Include -I../../SuiteSparse_config -shared -o umfsolver.dll umfsolver.o ../Lib/libumfpack.a ../../AMD/Lib/libamd.a ../../SuiteSparse_config/libsuitesparseconfig.a ../../CHOLMOD/Lib/libcholmod.a ../../COLAMD/Lib/libcolamd.a ../../metis-4.0/libmetis.a ../../CCOLAMD/Lib/libccolamd.a ../../CAMD/Lib/libcamd.a -lm -lrt ../../CHOLMOD/Lib/libcholmod.a ../../COLAMD/Lib/libcolamd.a ../../metis-4.0/libmetis.a ../../CCOLAMD/Lib/libccolamd.a ../../CAMD/Lib/libcamd.a -Wl,--add-stdcall-alias来检查字符串是否相等。即使String对象包含相同的值，也认为它们不相等。这是因为Java通常处理对象的方式。

幸运的是，Java有一个内置的方法。 ==
