java - 如何使我的代码输出为击键？

Question

如何才能将代码输出为击键？我知道我必须使用 Robot 类，但是如何使其输出为对象？

import java.util.HashSet;
import java.util.Set;
import java.awt.Robot;
import java.awt.event.KeyEvent;

public class MainClass {

public static Set<String> generatePowerSet(String inputString)
{
    Set<String> result = new HashSet<String>();
    result.add(""); // empty string is an element of the power set

    if (inputString != null && !inputString.isEmpty())
    {
        int n = 1 << inputString.length(); //2^n - the number of elements in the power set 
        StringBuilder sb = new StringBuilder();

        for (int i = 1; i < n; i++) // skip empty set, i = 0
        {
            int k = i; // current number to manipulate
            sb.delete(0, sb.length()); // clear the StringBuilder
            for (int index = 0; index < inputString.length() && k > 0; index++) // break early when k == 0
            {
                if ((k & 1) == 1) // include char at index if bit at that index is 1
                {
                    sb.append(inputString.charAt(index));
                }
                k >>= 1;
            }
            result.add(sb.toString());
        }
    }
    return result;
}

public static void permuteString(String bs, String end) {
    if (end.length() <= 1)
        System.out.println(bs + end);//I THINK I HAVE TO CHANGE SOMETHING OVER HERE
    else
        for (int i = 0; i < end.length(); i++) {
            try {
                String newString = end.substring(0, i) + end.substring(i + 1);

                permuteString(bs + end.charAt(i), newString);
            } catch (StringIndexOutOfBoundsException exception) {
                exception.printStackTrace();
            }
        }
}

public static void main(String args[])  {

    Set<String> powerSet = generatePowerSet("String");

    Set<String> allPossibilities = new HashSet<String>();

    for(String s : powerSet)
    {
        permuteString(" ", s );
    }
}
}

I got how to send one character out at a time but not Strings.

Robot 使用KeyEvent，并且没有简单的反向映射。相反，有一百万种方法可以插入大胜利；以下是一些示例:

1. 使用 javax.swing.Timer 将文本一次滚动一个字符，如图 here .

2. 争夺“胜利!”图像，如图here .

3. 淡化“胜利!”中，如图here .
