Variable parameters and health conditions of Java classroom exercises

/*
Someone invited A,b,c,d,e,f 6 people to attend a meeting, these 6 people are a little strange, because they have a lot of requirements, known:
1) A/b two persons at least 1 persons attend the meeting;
2) A,e,f 3 out of 2 people attended the meeting;
3) B and C Two people unanimously decided that either two people go, or neither of them go;
4) Only 1 of the A,d two are attending the Conference;
5) As long as 1 people attend the meeting of the C,d two persons;
6) If D does not go, then E decides not to go.
So what are the last few people who attended the meeting?
*/

The mutable parameter must be in the last item. When there is more than one variable parameter, there must be one that is not the last, so only one variable parameter is supported.

The written form of the variable parameter is as follows:
void A (Boolean a,int ... args) {method body}

1) must be three points;

2) ... Between the variable type and the variable name, there are no spaces before and after it can be;
3) The application of the variable parameter is actually the Java Virtual machine dynamically opened an array;

4) No other things can be added after three points.
