DanChisholm's assertion question

[naraharirao mocherla]

The answes for this question are b,c and e...

How come the answer b is corect?
When assertions disabled it prints nothing..(Is it b'coz it does not have any println statement in the method m1???

The method B is returning c right???

  class B {
  int a, b, c;
  private void setA(int i) {a = i;}
  private void setB(int i) {b = i;}
  private int m1 (int i) {
    c = a + b + i; 
assert c < 200 : c;
 return c;
  }
  public static void main (String[] args) {
    B b = new B(); 
b.setA(50);
 b.setB(100);
 b.m1(50);
}}
 
Which statements are true? 
 
a.  If assertions are not enabled at run time it prints an error message. 
b.  If assertions are not enabled at run time it prints nothing. 
c.  With assertions enabled it prints an error message. 
d.  With assertions enabled it prints nothing. 
e.  The assert statement is being used to check a postcondition--something that must be true when the method completes successfully.

Yes, there are no print statements anywhere, so nothing is ever printed unless there is an AssertionError.

dear naraharirao,
if assertions are not enabled at run time then the code will be same as

see commented line.

class B {
int a, b, c;
private void setA(int i) {a = i;}
private void setB(int i) {b = i;}
private int m1 (int i) {
c = a + b + i;
//assert c < 200 : c;
return c;
}
public static void main (String[] args) {
B b = new B();
b.setA(50);
b.setB(100);
b.m1(50);
}}


Hope this will help you
