Dynamic loading: A block of code would be loaded into the RAM only when it is required to be executed. Note: Static loading took place in the execution of structured programming languages. EX: c- language. Java follows the Dynamic loading.

When we compile Java program using javac tool, the Java compiler converts the source code into byte code. Let's see what is the meaning of class, public, static, void, main, String[], System.

It means it is visible to all. If we declare any method as static, it is known as the static method. The core advantage of the static method is that there is no need to create an object to invoke the static method. The main method is executed by the JVM, so it doesn't require creating an object to invoke the main method.

So, it saves memory. It means it doesn't return any value. String[] args or String args[] is used for command line argument. We will discuss it in coming section. Here, System is a class, out is an object of the PrintStream class, println is a method of the PrintStream class. We will discuss the internal working of System. As displayed in the above diagram, write the simple program of Java in notepad and saved it as Simple. When we have done with all the steps properly, it shows the following output:.

Write here:. There are many ways to write a Java program. The modifications that can be done in a Java program are given below:. Let's see the simple code of using var-args in the main method. We will learn about var-args later in the Java New Features chapter. If there occurs a problem like displayed in the below figure, you need to set a path. Since DOS doesn't recognize javac and java as internal or external command.
