Clearing console in Intellij-idea

Question

Could anyone tell me if it's possible to clear console in intellij-idea and how?

So far I have tried:

System.out.print("\033[H\033[2J");
System.out.flush();

and:

Runtime.getRuntime().exec("clear");

but any of those did work.

I'm using Intellij-idea ultimate 2017 2.4 and Linux Mint.

@AntonBalaniuc If any of those suggestions worked for me except printing new line 50x i would have not created this topic — stilltryingbutstillsofar, Sep 15 '17 at 14:58

The best thing would be to implement it into https://github.com/krasa/GrepConsole and send a pull request. — Meo, Sep 15 '17 at 15:10

Use Grep Console plugin for clearing it when it matches some output.

I don't believe you can, think of that window as a log file.

BTW, why would you want to clear that?

I'm developing a chess game and need to refresh the console everytime a player makes a move. – stilltryingbutstillsofar Sep 15 '17 at 15:02
@stilltryingbutstillsofar Why not just print a delimiter line. – Meo Sep 15 '17 at 15:05
@Meo Currently i print like 50 newlines but I would like to know if there's a way to clear it in intellij instead of doing this. – stilltryingbutstillsofar Sep 15 '17 at 15:07

For debugging purposes it's good to be able to clear the console (other IDEs have this feature). – Bogdan Dec 02 '19 at 12:13

OP wants it from the code, not from the IDE – ThCollignon Mar 27 '23 at 11:00

IntelliJ IDEA console is not a real terminal, so there is no command to clear it from your Java code.

See the issue here.

Try run your application in other terminal, then you can make a function like this:

public static void ClearConsole(){
    try{
        String operatingSystem = System.getProperty("os.name") //Check the current operating system
          
        if(operatingSystem.contains("Windows")){        
            ProcessBuilder pb = new ProcessBuilder("cmd", "/c", "cls");
            Process startProcess = pb.inheritIO.start();
            startProcess.waitFor();
        } else {
            ProcessBuilder pb = new ProcessBuilder("clear");
            Process startProcess = pb.inheritIO.start();

            startProcess.waitFor();
        } 
    }catch(Exception e){
        System.out.println(e);
    }
}
