jAvA逐行

public static String readString(String pathname) throws IOException { BufferedReader reader = new BufferedReader(new FileReader(pathname)); StringBuilder sb = new StringBuilder();; String line = ""; while ((line = reader.readLi...

java读入文件,并逐行输出,先在D://home建立个文件夹,然后创建一个a.txt文件,然后编辑文件,文本编辑的编码是utf-8,然后用流逐行读取输出,如下: import java.io.BufferedInputStream;import java.io.BufferedReader;import java.io.File;im...

FileWriter writer = new FileWriter(f2,true);//这里加true表示可追加 bw.write(line); bw.newLine(); bw.flush();//在后面填上这句,没这句你只是将数据写入io缓存,并没有写入文件,加上这句就可以了

public static void readTxtFile(String filePath){ try { String encoding="GBK"; File file=new File(filePath); if(file.isFile() && file.exists()){ //判断文件是否存在 InputStreamReader read = new InputStreamReader( new FileInputStr...

你是在随机生成双色球的红球埃。。 //定义String类型的一维数组,01 - 33 即双色球的红球 String[] pool = {"01","02","03","04","05","06","07", "08","09","10","11","12","13","14","15","16", "17","18","19","20","21","22","23","24","25"...

如果2个文件编码相同...下面的程序就应该没问题了...如果编码不同....呵呵....那就需要先知道编码了.... package my.code; import java.io.BufferedReader; import java.io.FileReader; import java.nio.charset.Charset; public class CompareT...

可以通过BufferedReader 流的形式进行流缓存,之后通过readLine方法获取到缓存的内容。 BufferedReader bre = null; try { String file = "D:/test/test.txt"; bre = new BufferedReader(new FileReader(file));//此时获取到的bre就是整个文件的...

/** * 以行为单位读取文件,常用于读面向行的格式化文件 * * @param fileName * 文件名 */ public static void readFileByLines(String fileName) { File file = new File(fileName); BufferedReader reader = null; try { System.out.println("...

public static void readTxtFile(String filePath){ try { String encoding="GBK"; File file=new File(filePath); if(file.isFile() && file.exists()){ //判断文件是否存在 InputStreamReader read = new InputStreamReader( new FileInputStr...

BufferedReader就这一个,其他的都是读字节
