Command vs Strategy

public class ConcreteStrategy implements BaseStrategy {

    @Override
    public void execute(Object argument) {
        // Work with passed-in argument.
    }

}

 

public class ConcreteCommand implements BaseCommand {

    private Object argument;

    public ConcreteCommand(Object argument) {
        this.argument = argument;
    }

    @Override
    public void execute() {
        // Work with own state.
    }

}
