我试图解码这些错误.

当我在不同的屏幕上查看我的应用程序时,它会出现.

这是下载到错误日志.

错误日志单击此处

class BankAccount {
    private String firstname;
    private String lastname;
    private int ssn;
    private int accountnumber = 0;
    private double accountbalance = 0.0;

    BankAccount() {
        firstname = "John Smith";
    }

    BankAccount(String firstname, String lastname, int ssn) {
        int accountnumber;
        double accountbalance;
    }

    public String getName() {
        return firstname;
    }

    public double getBalance() {
        return accountbalance;
    }

    public void setAccountNumber(int accountnumber) {
        return accountnumber;
    }

    public boolean equals(BankAccount ba) {
        return this.accountbalance == ba.accountbalance;
    }

    public void deposit(double amount) {
        return this.accountbalance …

我是aspectj的新手,我怀疑是否可以使用aspectj在jar文件中存在的函数之前注入代码.

import java.util.Scanner;

public class TextMsgDecoder {
   public static void main(String[] args) {

      String message;
      Scanner keyboard = new Scanner(System.in);

      System.out.println("Enter text:");
      message = keyboard.nextLine();

      System.out.println("You entered: " + message);


     if (message.indexOf("IDK") > 0) {
        System.out.println("IDK: I don't know");
      }
      if (message.indexOf("BFF") > 0) {
        System.out.println("BFF: best friend forever");
      }
     if (message.indexOf("JK") > 0) {
        System.out.println("JK: just kidding");
      }
     if (message.indexOf("TMI") > 0) {
        System.out.println("TMI: too much information");
      }
     if (message.indexOf("TTYL") > 0) {
        System.out.println("TTYL: talk to you later");
      }
   } …

string s="1 23";
string a;
a[0]=s[2];a[1]=s[3];
cout<<a;

在这里，我无法获得输出字符串 a。但是我可以通过 a[0] 获取所有单个元素。
