Using code editors without compilation capability

if you are using any code editor without compilation capability, you can compile Java source code in Windows Command Prompt or Mac Terminal:

In Windows, you can open Command Prompt and set the current path to current folder by typing "cmd" in the file explorer address bar.

Let's say you java file is called javafile.java

1) Use the corresponding command prompt or terminal commands to get to the correct directory;

cd <enter folder pathname>

2) Use the following command to compile your java source file. This step compile the sourece file into bytecode file (in this case javafile.class)

javac javafile.java

3) Use the folowing command to run your compiled java file.

java javafile

Make sure you have JDK installed. You can check by typing "javac" into your Command Prompt(cmd)/Powershell in Windows or Terminal in MacOS. If it shows "javac comand not found" that means JDK is not installed on your machine. Otherwise it is installed.

Let's first save the following content in a file called Sample.java and save it in a folder called "Example" on your desktop.

public class Sample

{

public static void main(String[] args)

{

System.out.println("My first program");

}

}

Compile in Windows Command Prompt (cmd)/Powershell or Mac Terminal

In Windows, you can open Command Prompt and set the current path to current folder by typing "cmd" or"powershell" in the file explorer address bar.

Alternatively you can use the cd command in command prompt or terminal commands to get to the correct directory;

cd <enter folder pathname>

2) Use the following command to compile your java source file. This step compile the sourece file into bytecode file (in this case Sample.class)

javac Sample.java

3) Use the folowing command to run your compiled java file.
