Java OCA OCP Practice Question 1467

Question

Which of the following code snippets will print exactly 10? 

1.  Object t = new Integer (106); 
    int k =  ((Integer) t).intValue ()/10; 
    System.out.println (k); /*from   w  w  w  . j  a  v a2  s  .c  om*/

2.  System.out.println (100/9.9); 

3.  System.out.println (100/10.0); 

4.  System.out.println (100/10); 

5.  System.out.println (3 + 100/10*2-13);

Select 3 options

  • A. 1
  • B. 2
  • C. 3
  • D. 4
  • E. 5 


Correct Options are  : A D E

Note

For Code 1.

Since both the operands of / are ints, it is a integer division.

The resulting value is truncated and not rounded.

Therefore, the above statement will print 10 and not 11.

For Code 5.

precedence of / and * is same and is higher than + and -.
