Are highly portable.
Java is a object oriented and class-based programming language. It was developed by Sun Microsystems on the 23rd of May, 1995.
Java was designed by a software engineer called James Gosling and it is originally owned by Oracle. Also, worthy of mention is the fact that Java was originally known as Oak.
Generally, Java as a software application usually are developed having a ".jar", ".class" or ".java" filename extensions.
Because Java byte code is the same on all computers, compiled Java programs are highly portable. This simply means that, the Java byte code was designed such that it has very few implementation dependency, thus, once the code is written, it can run on all computer platforms that supports the Java programming language.
Hence, the Java byte code is a write once, run anywhere software program.
The Java byte code instructions are read and executed by a computer program known as a Java Virtual Machine (JVM).
Additionally, Java program is used for developing varieties of applications such as, mobile, desktop, games, web and application servers etc.
the answer to your question would be something called hertz. the unit of measurement called a hertz, which is one cycle per second, is used to measure clock speed. within one cycle, your computer processes, refreshes, or updates itself to the changes that it is going through. in the case of computer clock speed, one hertz equals one tick per second. the clock speed of computers is usually measured in megahertz (mhz) or gigahertz (ghz)
