When compared to other programming languages you will come to know that why is Java programming language secure and that is what this blog is all about. With respect to Java’s fame security is the prime factor to be looked at.
Why is Java Secure Language?
1) Own Memory Management
The memory management mechanism is unique and is owned by Java. There is no need for manual intervention for garbage collection and everything is handled automatically. There is no need for a headache to free the memories. It drastically reduces the programmer overhead. Therefore the programmer’s hand must be free from memory management. Relieving the memory in Java is the job of JVM.
2) No Pointers
There is no support for the pointers concept in Java. Some of the arbitrary memory locations can be addressed with the help of pointers for doing read and write operations which are unauthorized. This does not serve the purpose of being secured. That is why users do not use the concept of pointers.
3) Access Specific Keywords
There is another benefit for Java security and it is nothing but having an access specific keyword. If access to a method is what programmer wants to give to other functions then the public keyword must be used. If he/she wants to hide the information then private keywords must be used. Access security issues can be controlled by the programmer like the above-mentioned line. For avoiding data to be overridden the programs can use the final keyword.
4) Compile Time Checking
It is more secure because of the ability of compile-time checking. For instance, if a method which is unauthorized and wanting to access a variable which private then the JVM will catch the error during compile time. For avoiding system crash JVM catches lots of errors which is actually a great thing. Two different results are produced with the help of two different Java compilers. Memory locations cannot be accessed other than the array as it checks array bounds carefully.
5) Exception Handling
This concept present in Java actually means that it can catch the results which are unexpected through exception handling and report the error to the programmer. Until the rectification of the error by the programmer this concept will not allow us to run the code. Thereby proving Java’s security.
