phyzguy said:The original reason for Java was to have a language where you could run the exact same code on any hardware. This is accomplished by having a 'virtual machine' on each hardware that runs the Java code. In answer to your question, there are many, many applications where run-time efficiency is irrelevant because the hardware is so fast. If I want to run a little piece of code on some web page, it doesn't matter whether the code takes 1 microsecond or 100 milliseconds to run, because in either case it happens instantaneously as far as the user is concerned. The important thing is that the code runs on whatever machine the user has and and doesn't crash.

Java is a high-level, object-oriented programming language that is widely used for developing applications on various platforms. It is the primary language used for Android development because it is platform-independent, has a large and active community, and offers extensive libraries and tools for developing mobile applications.
There are several advantages of using Java for Android development. Firstly, it is an established and mature language with a wide range of resources and support available. It also offers a large community of developers, making it easy to find help and resources. Additionally, Java is highly versatile and can be used to develop a variety of applications, from simple to complex. It also has a robust security system, making it a safe choice for developing mobile applications.
Yes, Java is a cross-platform language, which means that it can be used to develop applications for multiple operating systems and devices. This makes it an ideal choice for Android development, as it allows developers to create applications that can run on a wide range of devices without the need for significant modifications.
Java offers several features that make it an ideal language for Android development. These include its platform independence, automatic memory management, robust security, and extensive libraries and tools. Additionally, Java is highly scalable, making it suitable for both simple and complex applications. It also supports multi-threading, which is essential for developing high-performance applications.
While Java offers many advantages for Android development, it also has some drawbacks. One of the main disadvantages is that Java is a verbose language, which means that it requires writing more code compared to other languages. It can also be challenging to learn for beginners, particularly if they have no prior programming experience. However, with the help of resources and communities, these challenges can be overcome, and the benefits of using Java for Android development outweigh the drawbacks.
