给定一个Java文件，统计文件中的代码行

package class_1;

import java.io.BufferedReader;

import java.io.FileNotFoundException;

import java.io.FileReader;

import java.io.IOException;

public class LineCount {

public void read(String filePath){

try{

BufferedReader br = new BufferedReader(new FileReader(filePath));

String line = null;

int count = 0;

while((line = br.readLine())!=null){

count ++;

}

System.out.println("行数是：" + count);

}catch(FileNotFoundException e){

e.printStackTrace();

}catch(IOException e){

e.printStackTrace();

}

}

public static void main(String[] args) {

LineCount lc = new LineCount();

lc.read("D://Test.java");

}

}
