How to clear console in Java on Windows [duplicate]

Solution 1: Having tried multiple IDE’s, the console isn’t meant to be ‘cleared’ according to Java, whereas in C# or C++ yes you can clear the console because of the way that C# applications are implemented (see all the cmd stuff we sometimes go thru). And since Java is a high-level language, there is really no need for clearing the console from logs, etc.

How to clear console in Java on Windows [duplicate]

The link in answer by @Olivier does work but unfortunately most suggestions use a sub-process cls or don’t explain how to enable on Windows.

In latest Windows 10 you can use ANSI code support in Window Terminal, but not directly in CMD.EXE consoles. To enable for CMD.EXE add the registry key VirtualTerminalLevel mentioned in these answers for ANSI colours and then you can print the appropriate ANSI/VT codes directly without running a sub-process:

System.out.print("\033[2J\033[1;1H");

System.out.print(ANSI.CLEAR_SCREEN+ANSI.position(1, 1));

where simple definition of ANSI codes is:

Note that other terminals or such as those in IDEs may not support the above.

It is a line by line output, thus for administrative purpose it cannot be cleared. An alternative method to this is printing out bunch of blank spaces which gives an impression that it is cleared. Even commands like cls/clear puts enough blank spaces.

How do you clear the Java Console? [duplicate]

I have output messages displayed on the Java console for an application that started using webstart. Instead of the user manually clearing message, is there a way of clearing console messages in code?

These messages are printed at the rate of about 1000 per second and seem to end up using too much memory, i could have stopped the printing to console, but the requirement is to always have it.

You will not be able to clear that console, unless you find some handle on the classes for that console (which I doubt you would have access to).

The requirement you have has the inevitable requirement that the user will need to go in and manually clear the console every couple of minutes. I think that justifies a rethink about why the requirement exists and wether there is another solution to solve your problem.

Have you considered a different way of logging?

Seems to me the requirement should be rediscussed. If this isn’t an alternative then you may limit the amount of output, because a 1000 messages /s seems an awful lot to me.

Clear The Console Programmatically In Java

I created a sample Java application . I want to clear the window options, i.e.:

If the user presses 3 I need to programmatically clear all options. Something like Console.clear ?

Is there any way that I can do this with Java?

You will need to output a bunch of blank lines. Even in Windows/*nix, clear/cls doesn’t truly clear the screen, it just prints enough blank lines that you cannot see the previous text.

You can try System.out.print(«CLS»);

Or use loops to clear the screen like

public static void clearScreen()

and then call this method clearscreen (); if you want to clear.

Sorry my english is bad. 🙂 I just want to help you.

Clear the Console in Java

Use ANSI Escape Codes to Clear Console in Java
Use ProcessBuilder to Clear Console in Java

We have introduced how to get input from console in Java in another article. In this tutorial, we will look at the two ways that can be used to clean the console screen in Java. We will be looking at examples to learn how to execute Java clear screen commands at runtime.

Use ANSI Escape Codes to Clear Console in Java

We can use special codes called ANSI escape code sequences to change cursor positions or display different colors. These sequences can be interpreted as commands that are a combination of bytes and characters.

To clear the console in Java, we will use the escape code \033[H\033[2J . This weird set of characters represents the command to clean the console. To understand it better, we can break it down.

The first four characters \033 means ESC or the escape character. Combining 033 with [H , we can move the cursor to a specified position. The last characters, 033[2J , cleans the whole screen.

We can look at the below example, which is using these escape codes. We are also using System.out.flush() that is specially used for flushing out the remaining bytes when using System.out.print() so that nothing gets left out on the console screen.

public class ClearConsoleScreen   public static void main(String[] args)  System.out.print("Everything on the console will cleared");  System.out.print("\033[H\033[2J");  System.out.flush();  > >

Use ProcessBuilder to Clear Console in Java

In this method, we will use a ProcessBuilder that is a class mainly used to start a process. We can build a process with the commands that will clean the console.

ProcessBuilder() takes in the commands to execute and its arguments. The issue with this approach is that different operating systems can have different commands to clean the console screen. It is why, in our example, we check the current operating system.

At last, we are using the Process class to start a new process with inheritIO to set the standard input and output channels to Java’s I/O channel.

public class ClearScreen  public static void main (String [] args)  System.out.println("Hello World");  ClearConsole();  >   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);  >  > >
