There is no support for low level programming in Java, like pointers are missing. 5-

Garbage collection

There is no control over garbage collection in Java. That is programmer does not have any right to control the garbage collection. Java does not provide functions like delete(), free(). 6-

No Unsigned Types

Unlike C/C++, Java does not support unsigned int, unsigned char, ... etc. However in Java 8, API for unsigned long and unsigned int is introduced.
