修复名字和姓氏的输出

Question

我正在学习使用数组，我很困惑如何让我的输出列出：人名和姓或只是他们在比较两个薪水的结尾的名字。截至目前，它使用一名员工的名字和姓氏，就好像他们是两名独立员工的名字一样。此外，这种编码或您看到的任何可以改进的内容是否有任何问题？请理解，我只在第4周学习Java。

        doubleArray = new double[2];

    Scanner keyboard = new Scanner(System.in);
    //constructor to instantiate employees
    Nameofsalesman compare = new Nameofsalesman();
    // for loop to populate employeeArray
    System.out.print("What is the first name of the employee?:");
    compare.firstName = keyboard.next();
    stringArray[0] = compare.firstName;

    compare.lastName = keyboard.next();

    }
    else {
        System.out.println(stringArray[0] + " wow, you both earned the same! " + stringArray[1] + ".");
    }
}
