import java.io.File;
import java.util.Scanner;

public class Test {
public static void main(String[] args) {
System.out.println("行数: " + getLineCountOfFile("c:\\1.txt"));
}

public static int getLineCountOfFile(String filePath) {
int lineCount = 0;
Scanner scanner = null;
try {
scanner = new Scanner(new File(filePath));

while (scanner.hasNextLine()) {
System.out.println("文件内容: " + scanner.nextLine());
++lineCount;
}
} catch (Exception e) {
} finally {
if (scanner != null) {
scanner.close();
}
}
return lineCount;
}
