What Makes Java More Secure Than Other Languages? Read Here To Know!

The popularity of Java owes to the fact that it drives above $100 billion of business each year. On the enterprise front, above $2.2 billion are being spent in Java application server by the enterprises. Java encapsulates some amazing features that are not available in any other platforms or programming languages and those people who hire java developers love these features.


The security model of Java is one of the main architectural features that make it the most preferred choice when it comes to building enterprise level apps. Security becomes all the more important when software gets downloaded across network and is executed locally. Java effortlessly diminishes the vulnerabilities of security that are linked with applications or projects. Here’s a look at some of the main features that depict the security of Java platform:

No pointer usage:

Languages like C/C++ utilizes pointers which can lead to illegal access to memory blocks when pointer values are given to other programs. In contrast to C/C++, Java never utilizes any pointers. It uses its internal memory management mechanism. It only offers access to the data to the program in case its authorization is verified.

Concept of exception handling:

This enables Java to capture a range of errors that assist developers in getting rid of the threats of crashing the system.

Security model of Java:

It helps and protects users from programs that get downloaded from some non-trusted sources within a network through ‘sandbox’. It permits all the programs of Java to run within the sandbox and prevents any activities from non-trusted sources like writing or reading the local disk, developing any new process, etc.

Tested re-usability of code:

The Java object encapsulation lends support to ‘programming by contract’. This permits the developers to re-use the code that has previously been tested while building applications of Java enterprise.

Defined order execution:

All the operations are defined in a precise execution order and all the primitives are defined with a size that is predefined. Thus, the code executed in distinct Java Virtual Machines does not possess a different execution order.

Safety from security attacks:

This permits developers to declare methods or classes as final. Since, any method or class declared as final cannot be overridden; the developers get to protect the code from attacks of security like creation of a subclass and replacing it with override methods and original class.

Mechanism of garbage collection:

This further aids to the measures of security of Java. It offers a storage allocation and helps in recovering unutilized memory in place of de-allocating memory via manual action. This assists developers in ensuring the reliability of the program during its execution and avoiding any JVM crash due to wrong freeing of memory.

Type safe reference casting in JVM:

JVM monitors you every time you use an object reference. In case you try to cast a reference to a distinct type, it makes the cast invalid.

Functionality of access control:

The access control functionality of Java on methods and variables provide secure program by preventing access to objects from non-trusted sources.

The above mentioned features clearly prove that projects created with Java provide more security as compared to any other language. Apart from these, structured handling of errors contributes to a great extent to the security model of Java. It is the developers’ responsibility to adopt the best practices while building enterprise level applications.
