Solved If else statement gives syntax error

I have a problem with my code.

When I add an else statement to my code if gives the following errors:
1.) Syntax error, insert "}" to complete Statement
2.) Syntax error on token "}", delete this token

Here's my code:

Code:

if (GeneratorClass.generators.containsKey(generatorLocation));
                    {
                       
                        GeneratorClass.removeGenerator(generatorLocation);
                        generatorLocation.getBlock().setType(Material.AIR);
                        generatorLocation.add(0, 1, 0).getBlock().setType(Material.AIR);
                        generatorLocation.subtract(0, 0, 1).getBlock().setType(Material.AIR);
                       
                    } else {
                        player.sendMessage(ChatColor.RED + "That's not a generator!");
                    }

Here is my whole class:

                        player.sendMessage("Location: " + "x= " + x + ", y= " + y + ", z= " + z);
                       
                    }
                   
                } 
               
            }
   
        }
       
        return false;
   
    }
       
}

I can't figure out why it gives these errors. Help would be appreciated

 

if (GeneratorClass.generators.containsKey(generatorLocation)); <------ HERE {

GeneratorClass.removeGenerator(generatorLocation);
generatorLocation.getBlock().setType(Material.AIR);
generatorLocation.add(0, 1, 0).getBlock().setType(Material.AIR);
generatorLocation.subtract(0, 0, 1).getBlock().setType(Material.AIR);

} else {
player.sendMessage(ChatColor.RED + "That's not a generator!");
}

Note: orange is not supposed to go into the code. its just notes

the ";" after the if doesn't need to be there. The ";" is bad in a if because the "{" says what to do if true, the ";" is at the end of a void, which means go to next line, you can only have one of them.

Don't worry, we all make sili mistakes

Thanks, I didn't see it.
