Robust and secure

Java is a robust language.It provides many safeguards to ensure reliable code .It has strict compile time & runtime checking for data types.It has designed a garbage collected language relieving the programmers virtually all memory management problems .Java also incorporates the concept of exception handling which captures series errors and eliminates any risk of crashing the system.

Security becomes more important for an language that is used for programming on internet.Threat of viruses & abuse of resources are every where.Java ensures not only verifies all memory access but also ensure that no viruses are communicated with the applet.The absence of pointers in Java ensures that program cannot gain access to memory locations without proper authorization
