Question

I have a syntax error and I don’t Know how to fix it. The code appears correct to me, but Eclipse is telling me that “Constructor call must be the first statement in a
constructor” at the methods setName() and setAge()

 public class KeywordThis {


    private String name;
    private int age;

    public KeywordThis(){

        this.name = "NULL";
        this.age = 0;

    }

    public KeywordThis(String s, int a){

        this.name = s;
        this.age = a;

    }

    public KeywordThis(String s){

        this.name = s;      
    }

    public KeywordThis(int a){

        this.age = a;

    }

    public int setAge(int a){

        this(a);
    }

    public String setName(String s){

        this(s);
    }






    public static void main(String args[] ){








    }


}

Answer 1

You cannot call a constructor like that from an instance method. You want your setter to change the value of the object you already have, not create a new one. I think you mean to do this:

public void setAge(int a){

    this.age = a;
}

public void setName(String s){

    this.name = s;
}

Also note that your setters don’t usually return values, so I’ve changed them to return type void.
