Why the output is "infinity loop"??

Question

for (int i=0; i <5;){
i=i++;
System.out.print (i);
}

Answer 1

i = i++; first post increament operator does like
i = i ; Next it does i = i +1 but, it will overridden by i = i result.

Am not sure what exactly happens but it will not store increment result.. Its may be depending upon sequence of operation done by stack operations internally, it store a temp variable.
Here, internally its happens :
int temp = i;
i = i+1 ;
i = temp;

Because of this sequence it will loss its increment result..

Just put i++; it will not an Infinite loop..
Else take another variable like
j = i++;
So here,
int temp = i;
i = i+1;
j = temp;
So Here, j = i happens, next i= i+1 will retain its increment value also.. But with same variable it's incrementation result will loss...
Hope it helps....
