Category: Disadvantage

Java provides automatic garbage collection that cannot be controlled by the programmer. It doesn’t provide the methods like delete() and free() to free the memory. However, due to the various disadvantages, Java is one of the most used programming languages due to its advantages, making it platform-independent, secure and a robust programming language.

Java lacks when it comes to interacting directly with machines, making it less viable for the software that needs to run quickly and run directly with the machine, as explicit pointers are also missing in Java.

Java programming language is a bit costly due to its higher processing and memory requirements. We need better hardware to run the Java program.

Java program consumes more memory since it runs on top of Java virtual machine.

Java needs to be interpreted during runtime, which allows it to run on every operating system, but it also makes it perform slower than the languages like C and C++. On the other hand, the C++ program needs to be compiled on each operating system, directly to binary and therefore runs faster.
