如何把带参数的成员方法输出？怎么弄

class People{
    People(){
        name = "wumingsi";
        age = 20;
    }
    public void setName(String a){
        name = a;
        System.out.println("名字:"+name);
    }
    String getName(){
        return name;
    }
    public void setAge(int b){
        age = b;
    System.out.println("年龄:"+age);
    }
    int getAge(){
        return age;
    }
    String name;
    int age;
}
public class People1{
    public static void main(String[] args){
        People c=new People();
        c.setName();
        People d=new People();
        d.setAge();
    }
}

把26, 28行包在System.out.println(...)中
或在第10行17行下在加一行System.out.println(name) 和 System.out.println(age)

class People{
    People(){
        name = "wumingsi";
        age = 20;
    }
    public void setName(String a){
        name = a;
        System.out.println("名字:"+name);
    }
    String getName(){
        System.out.println("名字:"+name);
        return name;
    }
    public void setAge(int b){
        age = b;
    System.out.println("年龄:"+age);
    }
    int getAge(){
        System.out.println("年龄:"+age);
        return age;
    }
    String name;
    int age;
}
public class People1{
    public static void main(String[] args){
        People c=new People();
        c.setName();
        People d=new People();
        d.setAge();
    }
}
