-0.0 |
- |
|
8 |
SOP(Math.max (-0.0, +0.0)); |
+0.0 |
|
|
9 |
SOP( Math.min(-0.0, +0.0)
= = Math.max (0.0, +0.0))); |
True |
The oder of floating or the double values is Infinity->Negative Numbers/Fractions->-0.0->+0.0->positive
numbers/Fractions->Infinity |

Integer i = new Integer("10");
i.toString() = = i.toString(); |
True |
Only upto 0 to 10 remaining all results false for both Integers, Bytes. The toString()
method returns String equivalent of this String object. It creates a new object
each time it is called. The = = operator compares the bit patterns of the two object
references and not the actual String contents. |
