Return Confusion...

Question about the task

Resolved

In line 19 return null is the only option i think there is if i need to only return a non-empty string. Or skip that return statement completely but then how should I avoid this error "Solution.java:19: error: missing return statement". Something like this,

public static class Idea {
    public String s;
    public String getDescription() {
        if(!((s.equals(null)) && (s.equals("")))) {
            return s;
        }
        //return ? or how to skip this error "Solution.java:19: error: missing return statement"
    }
}

The actual code below...Thanks

1. In the Solution class, create the public static Idea class
2. In the Idea class, declare a public String getDescription() method that returns any non-empty string
3. In the Solution class, create a static public void printIdea(Idea idea) method that will display a description of the idea (what the getDescription method returns)

Requirements:

In the Solution class, create the public static Idea class.
In the Idea class, create the public String getDescription() method.
The getDescription method must return any non-empty string.
In the Solution class, create a public static void printIdea(Idea idea) method.
The printIdea method should display the idea description on the screen.

package com.codegym.task.task06.task0617; /* Notepad for new ideas */ public class Solution { public static void main(String[] args) { printIdea(new Idea()); } public static class Idea { public String s = ""; public String getDescription() { if(!((s.equals(null)) && (s.equals("")))) { return s; } return null; } } public static void printIdea(Idea idea) { System.out.println(idea.getDescription()); } }

    public static void printIdea(Idea idea) {
        System.out.println(idea.getDescription());
    }
}

Try this:

public String getDescription() {
    return "any non-empty string";
}
