 Question Submitted By :: Core-Java

Answer
# 1
Java does not use memory pointers explicitly. All the
programs in java are run under an area known as the sand
box. Security manager
determines the accessibility options of a class like reading
and writing a file to the local disk. Java uses the public
key encryption system to allow the java applications to
transmit over the internet in the secure encrypted form. The
bytecode Verifier checks the classes after loading.

Answer
# 2
Java is considered more secure than other languages for
several reasons:

* The Java compiler catches more compile-time errors;
other languages (like C++) will compile programs that
produce unpredictable results.
* Java does not allocate direct pointers to memory. This
makes it impossible to accidentally reference memory that
belongs to other programs or the kernel.
