my code regarding the simple String display is not showing the required output?

public class Zoo
{
    public String coolMethod(){
        return "wow !! baby..";
    }
    public static void main(String args[])
    {
        Zoo z=new Zoo();
        z.coolMethod();
    }
}

This is a simple code to display a string but it is not showing the desired output i.e. in this case string "wow !! baby.." .It is compiling and executing fine but not showing the result.

1st way

public class Zoo
{
    public String coolMethod(){
        return "wow !! baby..";
    }
    public static void main(String args[])
    {
        Zoo z=new Zoo();
       System.out.println(z.coolMethod()) ;
    }
}

2nd way

    public class Zoo
    {
        public void coolMethod(){
            System.out.println( "wow !! baby..");
        }
        public static void main(String args[])
        {
            Zoo z=new Zoo();
            z.coolMethod();


  }
}

In your coolMethod() method the return type is String. In order to display the result of this method, you have to return it void or use System.out.print(); . For your second problem is, you do not have main method inside your class.Create a new class Test then put this method 

    public static void main(String[] args) {
Moo m = new Moo();
m.useMyCoolMethod();
    }

Whenever you want to produce some output to your console, use System.out.print() method. For example:

System.out.print("fff"); System.out.print("ggggg");

will produce fffggggg. If you want to print the same result in separate line, use System.out.println. For example:

System.out.println("fff"); System.out.println("ggggg");

will produce
fff
ggggg

 public class Zoo
 {
  public String coolMethod(){
    return "wow !! baby.."; // return String
  }
 public static void main(String args[])
  {
    Zoo z=new Zoo();
    z.coolMethod(); //here you are getting "wow !! baby..", but you are not printing it.
 }
}

replace 

 z.coolMethod(); with System.out.println(z.coolMethod()); // now you will see the out put in console

You specified coolMethod() to return, not to print. There won't be any printed output. You also did not assign a string variable to z.coolMethod() nor wrap print around it so your desired output is lost.

The method coolMethod() just returns the String. But looks like you forgot to put the code to print the string. You may do like this

System.out.println(z.coolMethod());
