通过名称获取文件路径

Question

我正在使用Java尝试仅通过其名称检索位于C驱动器上的文件路径。例如，如果我有＆＃34; test.txt＆＃34;在我的桌面上它将返回C：//Users/LukesComputers/Desktop/test.txt。代码看起来像这样：

public String getPathByName(String fileName) { //Assume fileName equals text.txt and is located on the desktop

String path = //Calls something to get the path
return path;
}
