Question

Here is a sample program run: java Find lamb mary1.txt mary2.txt mary1.txt: Mary had a little lamb, mary1.txt: little lamb, little lamb, mary1.txt: Mary had a little lamb, its fleece was white as snow. mary1.txt: and everywhere that Mary went, the lamb was sure to go. mary2.txt: it made the children laugh and play to see a lamb at school. Use the following class as your main class: import java.io.FileNotFoundException; import java.io.File; import java.util.Scanner; /** This program searches files and prints out all lines containing a keyword. */ public class Find { public static void main(String[] args) throws FileNotFoundException { if (args.length < 2) { System.out.println("Usage: Find keyword sourcefile1 sourcefile2 . . ."); return; } String keyword = args[...]; for (int i = 1; i < ...; i++) { String filename = args[...]; . . . } } }
