Java IO流输出文本
使用FileWrite
代码
import java.io.File;
import java.io.FileWriter;
import java.io.IOException;
public class Test {
public static void main(String[] args) {
String path = "D:\\test";
String name = "Test.txt";
//保存路径文件夹不存在时创建
File file = new File(path);
if(!file.exists()) {
file.mkdirs();
}
try {
//File.separator为斜杠"\"
File outFile = new File(path + File.separator + name);
for(int i = 0; i < 6; i++) {
String txt = "第" + (i+1) + "行内容\r\n";
WriteTxt(outFile, txt);
}
} catch (Exception e) {
e.printStackTrace();
}
}
private static void WriteTxt(File file, String txt) {
FileWriter fw = null;
try {
//true不写的话方法默认为false,true:在文本原有基础上追加文本,false:覆盖原有文本
fw = new FileWriter(file, true);
fw.write(txt);
fw.close();
} catch (IOException e) {
e.printStackTrace();
} finally {
if(fw != null) {
try {
fw.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
}
}
