![]() The main method is executed by the JVM, so it doesn’t require to create object to invoke the main method. The core advantage of static method is that there is no need to create object to invoke the static method. static is a keyword, if we declare any method as static, it is known as static method.public keyword is an access modifier which represents visibility, public means visible in the entire program.class keyword is used to declare a class in java.Let’s see what is the meaning of class, public, static, void, main, String, (). Hello Simple Snippets Program Explanation Inside the main function paste the code typed below –.Click on -> File -> New Project -> Java -> Java Application -> Next. ![]() So quickly open up your Netbeans IDE (for the first program you can also use a basic text editor however I always prefer Netbeans IDE or any other IDE) Now lets see our very first java program. ![]() So this was all about the Setting up of Netbeans IDE and the PATH variable. SO the next time you try to execute a java program, the program will know exactly where the java compiler is located. Step 6: Click okay/Apply and then you are good to go.Copy this directory location and paste it as a new entry in this list as shown in the below diagram and then click okay. If you cannot find it, just go to your windows explorer and do the directory as follows – C:\Program Files\Java\jdk1.8.0_161\bin\. Search for the entry of the path of the java jdk bin as show below in the diagram. Step 5: Once you click edit you will see a list of entries (shown in the image below) of different executables.In the system variables search the variable named – path. Step 4: Here you can see 2 windows – uservariables and system variables.Step 3: In the System properties, advanced tab, you can see a button named environment variables, Click on it.Step 2 : Click on Advanced System Settings (Windows 10).Step 1 : Right Click on M圜omputer and click on properties.Thus its easier to set the PATH variable once in the system settings. It is possible to invoke the compiler without setting up the PATH variable, however you will need to provide the path everytime you want to invoke the compiler. ![]() Now this location needs to be set in the PATH variable so that when you compile any java code, the program knows where exactly to locate the java compiler. So when you compile the java code, a exe file called javac.exe is invoked which resides in the java directory as follows – C:\Program Files\Java\jdk1.8.0_161\bin\javac.exe The path variable is system variable which holds values to executables files that the system requires(not jsut for Java). Thats it, pretty much everything is sorted out except one thing – Setting up the PATH variable. Once you have finished downloading the bundle simply install it with Default setting. Next task is to install both Java and Netbeans IDE. Just select the Netbeans with JDK 8 option and download the full bundle. ![]() If you are starting with Java for the first time, you might want to install the Java + Netbeans bundle from the official website as follows – We will then try to understand the program line by line at an overview level. We will also write our first Hello World program in Java which will print the message – Hello World on the command prompt. The table below lists packages that are comprised in each profile.In this tutorial we will first install and setup our Netbeans IDE that we will be using for writing and running java programs. Each profile specifies a particular set of Java API packages and contains all of the APIs in profiles smaller than itself: compact1 is a subset of compact2, which is a subset of compact3, which in its turn is a subset of the full JRE. Three profiles that have been defined so far are named compact1, compact2, and compact3. ![]()
