Disadvantages of Java

In this section, we’ll discuss about the disadvantages of Java.

Like any programming language, Java is not perfect.

  • Performance

Java programs are converted to bytecodes when compiled. During execution, these byte codes are interpreted by the virtual machine. Thus, Java programs take longer time to run compared to programs written in C and C++. But this problem is being overcome with a Just-in-time Compiler (JIT).

  • Consumes More Memory

This is one of the biggest problems in Java. Java takes more memory space than the other native programming languages like C and C++. The Java Virtual Machine (JVM), stores metadata about classes and other objects in the background. This causes your programs to consume more memory.

  • Garbage collection

You have no control over garbage collection in Java. The Java Virtual Machine (JVM) takes care of everything for you. Sometimes this is not what you want.
