是否可以在运行期间使用Java清除Intellij中的控制台选项卡？ [英] Is it possible to clear the console tab during runtime in Intellij with Java?

问题描述

我试图在运行时使用Java清除Intellij中的控制台选项卡。

Im trying to clear the console tab in Intellij during run time with Java.

任何想法？

这就是我的尝试：

System.out.print("\033\143");

    public static void clrscr(){
        //Clears Screen in java
        try {
            if (System.getProperty("os.name").contains("Windows"))
                new ProcessBuilder("cmd", "/c", "cls").inheritIO().start().waitFor();
            else
                Runtime.getRuntime().exec("clear");
        } catch (IOException | InterruptedException ex) {}
    }

    public final static void clearConsole()
    {
        try
        {
            final String os = System.getProperty("os.name");

            if (os.contains("Windows"))
            {
                Runtime.getRuntime().exec("cls");
            }
            else
            {
                Runtime.getRuntime().exec("clear");
            }
        }
        catch (final Exception e)
        {
            //  Handle any exceptions.
        }
    }

    public static void clearScreen() {
        System.out.print("\033[H\033[2J");
        System.out.flush();
    }

推荐答案

您可以指定快捷方式控制台上的全部清除来自首选项>键映射。在下面的屏幕截图中，我分配了快捷方式 ALT SHIFT 1 来清除控制台。

You could assign a shortcut to Clear All on the Console from Preferences > Keymap. In the following screenshot I am assigning the shortcut ALT SHIFT 1 to clear the console.

要测试这个地方将光标放在控制台中并使用该按键组合。

To test this just place your cursor in the console and use that keystroke combination.

这是最简单的部分。接下来，您可以使用 java.awt.Robot 来执行该击键组合。例如：

That's the easy part. Next you can use java.awt.Robot to exeucte that keystroke combination. For example:

import java.awt.Robot;
import java.awt.event.KeyEvent;

public void clearConsole() {
    try {
        Robot robot = new Robot();
        robot.keyPress(KeyEvent.VK_ALT);
        robot.keyPress(KeyEvent.VK_SHIFT);
        robot.keyPress(KeyEvent.VK_1);
        robot.keyRelease(KeyEvent.VK_ALT);
        robot.keyRelease(KeyEvent.VK_SHIFT);
        robot.keyRelease(KeyEvent.VK_1);
    } catch (AWTException ex) {
        ex.printStackTrace(System.err);
    }
} 

使用机器人可能有点棘手，所以你可能不得不玩这个，包括在执行 ALT SHIFT 1 之前添加按键组合以将焦点切换到控制台

Use of Robot can be a bit tricky so you'll likely have to play around with that including adding a keystroke combination to switch focus to the console before executing ALT SHIFT 1
