Boolean error (Required Boolean ) in java

When the class conector.conexion(); if I use the command:

if (conector.conexion()) {
}

Error : Required Boolean  `conector.conexion()`

What is wrong?

Connection is not Boolean type class. Instead of if(conector.conexion()) you can use like below :

if(conector.conexion() != null) {
  //It ensure connection is not null
  //To check connection is not closed
  if(!conector.conexion().isClosed()) {
   //code...
  } 
}

Do following to check if connection instance has been created or not:

if(conector.conexion() != null){
     //code stuff
}
