Is it possible to use the external terminal when running a Java program through Netbeans?

What I mean is, I can switch to getting Netbeans output out on Linux bash or Windows cmd instead of using the internal Netbeans application console?

Assuming your class is an executable class, has a main method, navigate the terminal to the directory your class is in, then type:

// command to compile

javac Suaclasse.java

// Command to execute

java Suaclasse

Example:

    public class SuaClasse { 
        public static void main(String[] args){ 
           System.out.println("Hello World Pelo Terminal =D"); 
        } 
     }

Using the terminal:

    mac@pc:~$ javac SuaClasse.java
    mac@pc:~$ java SuaClasse
    Hello World Pelo Terminal =D

Not only is it possible but it’s super easy, as long as you’re with your environment variables (path) well configured. Also, for smaller applications I consider even easier (I only have problems generating the .jar[laughter]).

Example class:

public class MinhaClasse{
    public static void main(String[] args){
        System.out.println("Hello, world");
    }
}

In the CMD:

c\> javac MinhaClasse.java
c\> java MinhaClasse.class
Hello, world

In the terminal:

user@Desktop:~$ javac MinhaClasse.java
user@Desktop:~$ java MinhaClasse.class
Hello, world

    And for larger applications? with multiple classes and use of JPA/Hibernate, would it be feasible to use a command line? an application to map the Objects and display the log output in the terminal

    good question, Lucas Actually, no, in such cases it is best to use the IDE

  • The bigger the program, the more complex, and the more difficult it is to keep all files synchronized. Even in C/C++ programs, where it is customary to use a text editor and the terminal, the IDE starts to prove advantageous from a certain complexity.

    In my opinion, the easiest of the Java IDE is to already separate the sources from the classes, and to export everything to one .jar automatically (plus a matter of practicality). But there are people who do not dispense with the combination terminal + text editor, and, for these, tools such as Atom editor, Sublime Text or Vi/Vim have hundreds of plugins that make development more practical and simple

  • I get it, I will look more about these editors. If you recommend something (especially some plugin for VIM), I will be grateful, thank you

    Dude, I would recommend Atom, because it has a built-in plugin database, which makes it really easy to use, and direct connection to Git systems. From Vim, I don’t know much (I’m not a big fan, I find it hard to use).
