驾驶考试类问题

我一直在组装一个驱动器测试器来测试我一直在为作业分配的课程，但是我在测试器方面陷入了僵局，我不确定如何完成它并消除任何错误。

这是测试人员：

public class PersonTester 
{
public static void main(String[] args)
{
    System.out.println("PersonClassTester");
    System.out.println("*****************");
    System.out.println("");

    Person joeSmith = new Person();
    String "smith" = joeSmith.setSurName(); // All these statements with set surname and forname etc are apperantly not statements and require a semi-colon, even though they are there.
    String "joe" = joeSmith.setForName();
    int 25 = joeSmith.setAge();
    double 1.57 = joeSmith.setHeight();
    String "male" = joeSmith.setGender();

    joeSmith.toString();
    joeSmith.format();
} 
}

这样做的主要问题是Netbeans客户端指出突出显示的setter语句实际上不是语句，并且说尽管它们确实存在，但每个语句都需要使用分号。也就是说没有正式或实际的论据。我知道它们是什么，但是无论如何我都对它们感到困惑。

这是我需要通过测试器运行的类：

public class Person 
{
private String surName;   
private String forName;   
private int age;   
private double height;           
private String gender;

@Override
public String toString()
{
    return getClass().getName() + "[surName= " + surName + " forName= " + forName + " age= " + age + " height= " + height + " gender " + gender + "]";
}

public void format()
{
    System.out.format("%10s%10s%10d%10f%10s", surName, forName, age, height, gender);
}

public String getSurName()
{
    return surName;
}

public String getForName()
{
    return forName;
}

public int getAge()
{
    return age;
}

public double getHeight()
{
    return height;
}

public String getGender()
{
    return gender;
}

public void setSurName(String surName)
{
    this.surName = surName;
}

public void setForName(String forName)
{
    this.forName = forName;
}

public void setAge(int age)
{
    this.age = age;
}

public void setHeight(double height)
{
    this.height = height;
}

public void setGender(String gender)
{
    this.gender = gender;
}    
}

有关使类测试器正常运行的任何建议？测试人员完成工作后，剩下的任务就不成问题了。

编辑：程序已编译，但无法打印String语句。
