Answer 1

here is the code:

                import java.util.*;
                public class ForEachFun
                {
                        private int num;
                        public ForEachFun(int n){num=n;}
                        public void number(){num--;num/=5%2;}
                        public String toString(){return ""+num;}
                      
                        public static void main(String[] args)
                        {
                                ForEachFun [] m=new ForEachFun[4];
                                for(int i=0;i<m.length;i++)
                                if(i%3 ==1) m[i]=new ForEachFun(-5);
                                else
                                m[i]=new ForEachFun(8+i);

                                after these lines of code:

                                        //m[0]=8
                                        //m[1]=-5
                                        //m[2]=10
                                        //m[3]=11

                              
                                for(ForEachFun n:m)
                                n.number();

                                after these lines of code:

                                here's a close look what number() function is doing, basically it is only decreementing
                                value of num because 5%2=1 and any number devided by 1 is number itself
                                        //m[0]=8-1=7
                                        //m[1]=-5-1=-6
                                        //m[2]=10-1=9
                                        //m[3]=11-1=10
                                for(ForEachFun n:m)
                                System.out.println(n);
                        }
                }

final answer:

7
-6
9
10

7 -6 10
