please help

Problem 5.1- Uh oh, we have an imposter robot masquerading as one of our Robots. We need a bouncer to only allow the Robots on the guest list' in. To do this, we will create a RobotBouncer class that will ask every Robot for its line before it is allowed to proceed. The RobotBouncer will fix any Robots saying scary things. The specifications for the RobotBouncer class are as follows: 1. A RobotBouncer has three attributes: String linol, String linc2, String lines. These are the accepted lines, and they should be provided via a single constructor (i.e. RobotBouncer has only one constructor). 2. RobotBouncer has a method called tixrobot() . This method takes a single parameter of type Robot: the Robot being tested, and possibly fixed. This method should check if the Robot's line is equal to any of the accepted lines. o If the Robot being tested has a friend (ie the friend != null), fixkobot O must also check the friend Robot's line o If the Robot and the Eriond pass, the method returns the original Robot. o If the Robot passes and its friend fails, the friend should be removed as a friend from the original Robot by setting the attribute to null o If the original Robot fails, a new Robot must be made: Give the new Robot an acceptable line (i.e. either line 1/2/3). You can choose this arbitrarily. The new Robot should have its original name with a " - fixed" tagged on. For example, if the deviant Robot named "skynet", the new Robot should be named "skynet - fixed". The new Robot must still have the original Robot's friend. However, fixkubul() must check this Robot's line as well. If the original Robot's friend's line is not acceptable, the new Robot's friend attribute should be set to null as previously stated. o In a nutshell, bad Robots should have all references to them removed. And good Robots should remain completely unchanged, with the exception of the friend attribute if the friond is a bad Robot. Hint 1 You must check if two Strings are equal using the equals() method. stringl.equals(string) => true/talze. Hint 2 You will need to define some more accessor methods for Robot in Robot.java
