    Missing return statement error

    I get the message "90: error: missing return statement" when trying to compile this cod

    The line that it's referencing is just a curly bracket.

    Code:
    class Persons	{
    
    //Declare instance variables
    
    	private String name;
    	private String nationality;
    	private int age;
    	private int steps;
    	private int weight;
    	private int height;
    
    //Declare getter and setter methods
    
    	public String getName()	{
    		return name;
    	}
    
    
    	public String getNationality()	{
    		return nationality;
    	}
    
    
    	public int getAge()	{
    		return age;
    	}
    
    
    	public int getSteps()	{
    		return steps;
    	}
    
    
    	public int getWeight()	{
    		return weight;
    	}
    
    
    	public int getHeight()	{
    		return height;
    	}
    
    
    	public String setName(String n)	{
    		name = n;
    		return n;
    	}
    	
    	
    	public String setNationality(String z)	{
    		nationality = z;
    		return z;
    	}
    
    
    	public void setAge(int a)	{
    		age = a;
    	}
    
    
    	public void setSteps(int s)	{
    		steps = s;
    	}
    
    	public void setWeight(int w)	{
    		weight = w;
    	}
    
    	public void setHeight(int h)	{
    		height = h;
    	}
    
    	
    //Method that evaluates string value and prints applicable value
    
    	public String talk()	{
    
    	if (nationality == "American")	{
    		System.out.println("They speak English.");
    	}
    
    	else if (nationality == "German")	{
    		System.out.println("They speak German.");
    	}
    
    	else {
    		System.out.println("Unknown spoken language.");
    	}
    
          	}
    
    //Method that prints what's in the println statement the applicable number of times 
    
    based on the value of steps.
    
    	public void walk()	{
    		int x = 1;
    		while (x < steps) {
    			System.out.println("I'm walking.");
    			x = x + 1;
    		}		
    	
    	}
    
    //Performs the calculation based on the weight and height values passed to it.
    	public int calcBMI()	{
    		int bmi = weight / height;
    		return bmi;
    	}
    		
    }
    
      class PersonsTestDrive	{
    
    	public static void main (String[] args)	{
    
    
    		Persons[] myHuman;
    		myHuman = new Persons[2];
    
    		myHuman[0] = new Persons();
    		
    
    		  myHuman[0].setName("Joe");
    		  myHuman[0].setNationality("American");
    		  myHuman[0].setAge(30);
    	          myHuman[0].setSteps(4);

    			myHuman[0].getName());

    			myHuman[1].getAge());
    
    			myHuman[1].talk();
    			myHuman[1].walk();
    
    			System.out.println("Person two's Body Mass 			
    
    			Index is:" + myHuman[1].calcBMI());
    	}
    
    }

    take a look at this function
    public String talk()
    u can see, this function should be returning a string, so can you take a look and confirm that this method/function is in fact returning a string?
    Cheers
