推荐答案

您需要这个导入：

import java.awt.Toolkit;

如果你想要它，无论如何，只需打开它：

If you are wanting it on no matter what, just turn it on with:

Toolkit.getDefaultToolkit().setLockingKeyState(KeyEvent.VK_CAPS_LOCK, true);

如果您想首先检查它是否关闭，请将其打开：

If you want to check first if it is off, then turn it on:

if (!Toolkit.getDefaultToolkit().getLockingKeyState(KeyEvent.VK_CAPS_LOCK)) {
        Toolkit.getDefaultToolkit().setLockingKeyState(KeyEvent.VK_CAPS_LOCK, true);
    }

最后，如果你想在两种状态之间切换：

Lastly, if you want to toggle between the two states:

if (Toolkit.getDefaultToolkit().getLockingKeyState(KeyEvent.VK_CAPS_LOCK)) {
        Toolkit.getDefaultToolkit().setLockingKeyState(KeyEvent.VK_CAPS_LOCK, false);
    } else {
        Toolkit.getDefaultToolkit().setLockingKeyState(KeyEvent.VK_CAPS_LOCK, true);
    }
