What are the constructors are used to create an object of the file class?
There are three constructors that can be used to create a File class.public File(String path). 'path' is basically the full pathname to the file in your current directory.public File(String path, String name). You can also separate the path and filename. 'name' would represent the filename and 'path' would represent the name of the directory.public File(File directory, String name). This is somehow similar to the previous way; however, directory is a File object rather than a String object.To create a new File object:File newFile = new File("something");
What search criteria would be used to find the lines within the MERCURY file about clients?

How do you search the given word in all files from the directory in java?
The program below will search all non-directory files in the starting directory. If you want to search all subdirectories, you'll have to modify it to recurse a bit. Note that this will also only do plain text searches of files. It will most likely not find your string in a MS Word .doc file. Also note that this will not find multiple-line search strings, since it reads and checks one line of the file at a time. { final String dirName; // path of directory you want to search final String str = ""; // string to search for final File dir = new File(dirName); for (File f : dir.listFiles()) { if (!f.isDirectory()) { System.out.println(f + ": " + fileContains(f, str)); } } } // returns true iff f contains str private static final boolean fileContains(final File f, final String str) throws IOException { final BufferedReader in = new BufferedReader(new FileReader(f)); String currentLine; while ((currentLine = in.readLine()) != null) { if (currentLine.contains(str)) { in.close();return true; } } in.close(); return false; }

What is a search string?
If I opened WikiAnswers on the internet and inside the "ask window" I put the question, "What is a search string?", that phrase, the part inside the quote, would become "the search string". Computers are quite efficient at searching for patterns in large databases. When the computer finds the specified search string, this answer would be displayed. I just verified it, and that's exactly what it does. RB
