I am been having a great curiosity.
I have written some java code & it is showing Null Pointer Exception. I am curious to know
Why java gives Null Pointer Exception even if it does not support pointers?
Java does support pointers (which you use everytime you have a
.or a[).It doesn’t support pointer arithmetic – i.e. the ability to manipulate a pointer into another pointer using math.
To point this out to converted C/C++ programmers, they did not carry the C name over, but named it something else. At the JVM level everything is pointers, but as Java programmers only see this when using references, the exception is badly named.
