Autonomous Help

[Mr.Roboto3335]

I wanted to know how to make a motor wait and then move in autonomous.

Autonomous Code So Far:

 public void autonomousPeriodic()
    {
        ShooterFront.set(50);
        ShooterBack.set(50);
      //Wanted to add 3 second wait
        servo.setAngle(90);
      //Wanted to add 3 second wait  
        servo.setAngle(180);
      //Wanted to add 3 second wait
        servo.setAngle(90);
      //Wanted to add 3 second wait  
        servo.setAngle(180);
      //Wanted to add 3 second wait  
        servo.setAngle(90);
      //Wanted to add 3 second wait  
        servo.setAngle(180);
    }
