每个框包含多个信息的数组

Question

所以我有一个练习问题，我应该用员工的信息创建一个数组，并将其传递给类；我的代码有一个问题，我似乎想不出来。

代码的目的是：将代码中看到的信息放入数组，然后传递给类中的方法，然后打印给用户。（类中的代码非常好，因此这里没有包括它）。

    // The Scanners.
    Scanner input = new Scanner(System.in);
    Scanner scan = new Scanner(System.in);
    
    // Taking Number Of Employees From The User.
    System.out.println("How many employees are there: ");
    int numberOfEmployees = input.nextInt();
    
    //Creating An Array With The Size Of Employees Entered By The User.
    Employee[] E = new Employee[numberOfEmployees];
    
    // Filling Out Information About Employees In Array.
    for(int i = 0; i <= E.length-1; i++){
        System.out.println("Enter employee " + i + "'s name: ");
        String name = scan.nextLine();
        
        System.out.println("Enter employee " + i + "'s birth date: ");
        String bday = scan.nextLine();
        
        System.out.println("Enter employee " + i + "'s salary: ");
        double salary = input.nextDouble();
        
        System.out.println("Enter employee " + i + "'s overtime: ");
        int overtime = input.nextInt();
        
        E[i] = (name, bday, salary, overtime);
    }
    
    System.out.println("Employee's Information"
            + "\n----------------------"
            + "\n----------------------");
    
    for(int i = 0; i <= E.length-1; i++){
        E[i].print();
    }
}

Answer 1

这里有两个问题需要解决。

首先，不要创建多个scanner对象，读取system.in。我知道你这么做了，因为这个问题（检查一下）：扫描器在使用next（）或nextFoo（）后跳过了nextLine（）？-但是除了创建另一个扫描器之外，还有另一个解决方案。

第二个问题在这里：

E[i] = (name, bday, salary, overtime);

E[i] = new Employee(name, bday, salary, overtime);

在代码段中考虑这一点时：

Scanner scan = new Scanner(System.in);
// Taking Number Of Employees From The User.
System.out.println("How many employees are there: ");
int numberOfEmployees = scan.nextInt();
scan.nextLine(); // <- reads the newline from the console

//Creating An Array With The Size Of Employees Entered By The User.
Employee[] E = new Employee[numberOfEmployees];

// Filling Out Information About Employees In Array.
for(int i = 0; i <= E.length-1; i++){
    System.out.println("Enter employee " + i + "'s name: ");
    String name = scan.nextLine();
    
    System.out.println("Enter employee " + i + "'s birth date: ");
    String bday = scan.nextLine();
    
    System.out.println("Enter employee " + i + "'s salary: ");
    double salary = scan.nextDouble();
    
    System.out.println("Enter employee " + i + "'s overtime: ");
    int overtime = scan.nextInt();
    
    // create a new employee with the entered information and save in the array
    E[i] = new Employee(name, bday, salary, overtime);
}
