Short Circuit Operators are quite similar to bitwise operators except for the following differences.
Case 1.
x&&y =>> y will be evaluated if and only if x is true.If x is false then y won't be evaluated.
Case 2.
x | | y =>> y will be evaluated if and only if x is false .If x is true
then y won't be evaluated.
Example 1.
int x=10 ,y =15;
if( ++x <10 & ++y > 15 )
{
x++;
}
else
{
y++;
}
System.out.println( x+".........."+y);
output is : 11 ......17
int x=10 ,y =15;
if( ++x <10 && ++y > 15 )
{
x++;
}
else
{
y++;
}
System.out.println( x+".........."+y);
output is : 11 ......16
Example 3.
int x=10 ,y =15;
if( ++x <10 | ++y > 15 )
{
x++;
}
else
{
y++;
}
System.out.println( x+".........."+y);
output is : 12 ......16
Example 4.
int x=10 ,y =15;
if( ++x <10 && ++y > 15 )
{
x++;
}
else
{
y++;
}
System.out.println( x+".........."+y);
output is : 12 ......16
Example 5. Choose the correct Option?
int x=10;
if(++x<10 && x/0 >10)
{
System.out.println( "Hello");
else
{
System.out.println( "Hi");
(a) Compile Time Error
(b)Runtime Exception / By Zero
(c)Hello
(d)Hi
Ans: Hi
Hint: If block's condition is false that is why the else block will be executed.
