What is the output of this program?

class average
 {
         public static void main(String args[])
         {
             double num[] = {5.5, 10.1, 11, 12.8, 56.9, 2.5};
             double result;
             result = 0;
             for (int i = 0; i < 6; ++i)
                  result = result + num[i];
 	    System.out.print(result/6);
           }
      }

2) What will the output of the following program?

public class Test{
       public static void main(String args[])
  {
        float f = (1 / 4) * 10;
             int i = Math.round(f);
             System.out.println(i);
       }
 }

3) Determine output:

public class Test{
 int i = 34;
  public static void main(String args[])
  {
 	Test t1 = new Test();
 	Test t2 = new Test();
 	t1.i = 65;
 	System.out.print(t1.i);
 	System.out.print(t2.i);
 	}
 }

      {
         public static void main(String args[])
          {
             int x;
             x = 5;
             {
 	        int y = 6;
 	        System.out.print(x + " " + y);
             }
             System.out.println(x + " " + y);
         }
      }

          {
             boolean var1 = true;
 	    boolean var2 = false;
 	    System.out.println((var2 & var2));
         }
      }
