post increment operator java
- by srandpersonia
I can't make heads or tails of the following code from "java puzzlers" by joshua bloch.
public class Test22{
public static void main(String args[]){
int j=0;
for(int i=0;i<100;i++){
j=j++;
}
System.out.println(j); //prints 0
int a=0,b=0;
a=b++;
System.out.println(a);
System.out.println(b); //prints 1
}
}
I can't get the part where j prints 0.
According to the author,
j=j++
is similar to
temp=j;
j=j+1;
j=temp;
But
a=b++
makes b 1.
So it should've evaluated like this,
a=b
b=b+1
By following the same logic, shouldn't
j=j++
be evaluated as,
j=j
j=j+1
Where does the temp come into picture here?
Any explanations would be much appreciated. << I'm breaking my head over this. ;)
Thanks in advance.
