There are many reason for java is secure programming languages.

 No pointers:-

                                  which means that a Java program cannot address arbitrary memory

                                  locations in the address space.

bytecode verifier:-

which operates after compilation on the .class files and checks forsecurity issues before execution. For example, an attempt to access an array elementbeyond the array size will be rejected. Because buffer overflow attacks are responsible for      most system breaches, this is an important security feature.

 Fine-grained control over resource access for both applets and applications.

 For  example, applets can be restricted from reading from or writing to disk space, or can beauthorized to read from only a specific directory. This authorization can be based on whosigned the code  and the http address of thecode source. These settings appear in a java.policy file. 

 A large number of library functions

for all the major cryptographic building blocks andSSL (the topic of this tutorial) and authentication and authorization (discussed in thesecond tutorial in this series). In addition, numerous third-party libraries are available foradditional algorithms.
