in this code, the integer on each line shows the line number that is not part of code: what are the parameters of sum: ____   1  public static int sum(int x, int y){   2     int z = x +y;   3     return z;   4 }      5 public static void main(String[] args){    6    …    7      sum(a+2, b);    8  …    9 }

Consider the following piece of code. (The numbers on the left margin denote line numbers.) line#01 public class funcRef {02     private int n;03     public funcRef (int m) {n = m;}04     public static void func (funcRef t) {t.n++;}05     public static void main (String [] args) {06         funcRef t1, t2;07         t1 = new funcRef(20);08         t2 = t1;09         System.out.print(t2.n);10         func(t1);11         System.out.print(t2.n);12         func(t1);13         System.out.print(t1.n);14         func(t2);15         System.out.print(t1.n);16         func(t2);17         System.out.print(t1.n);18         System.out.print(t1.n);19         return;20     }21 } Out of the following, tick the true statements and leave the false statements unticked.(More than one of the statements could be true. You get full marks only for marking all the statements correctly. There are no partial marks.) A. The output of the program will be 202022222222. B. When func(t1) is called in line…
