What is type safety in Java?

Why is C not type safe?

C and C++: not type safe. C's standard type system does not rule out programs that the standard (and common practice) considers meaningless, e.g., programs that write off the end of a buffer. So, for C, well typed programs can go wrong. C++ is (morally) a superset of C, and so it inherits C's lack of type safety.

What is type safe code?

Type-safe code accesses only the memory locations it is authorized to access. ... For example, type-safe code cannot read values from another object's private fields. Robin Milner provided the following slogan to describe type safety: Well-typed programs cannot "go wrong".
