Java如何创建文件并写入内容呢？

实现思路:
    创建文件
	写入文件内容

package com.java265.other;

import java.io.BufferedReader;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.util.UUID;


public class ForFile {
//生成文件路径
private static String path = "D:\\test\\";
//文件路径+名称
private static String filenameTemp;


public static boolean createFile(String fileName,String filecontent){
Boolean bool = false;
filenameTemp = path+fileName+".txt";//文件路径+名称+文件类型
File file = new File(filenameTemp);
try {
//如果文件不存在，则创建新的文件
if(!file.exists()){
file.createNewFile();
bool = true;
System.out.println("success create file,the file is "+filenameTemp);
//创建文件成功后，写入内容到文件里
writeFileContent(filenameTemp, filecontent);
}
} catch (Exception e) {
e.printStackTrace();
}
return bool;
}


public static boolean writeFileContent(String filepath,String newstr) throws IOException{
Boolean bool = false;
String filein = newstr+"\r\n";//新写入的行，换行
String temp = "";
FileInputStream fis = null;
InputStreamReader isr = null;
BufferedReader br = null;
FileOutputStream fos = null;
PrintWriter pw = null;
try {
File file = new File(filepath);//文件路径(包括文件名称)
//将文件读入输入流
fis = new FileInputStream(file);
isr = new InputStreamReader(fis);
br = new BufferedReader(isr);
StringBuffer buffer = new StringBuffer();
//文件原有内容
for(int i=0;(temp =br.readLine())!=null;i++){
buffer.append(temp);
// 行与行之间的分隔符 相当于“\n”
buffer = buffer.append(System.getProperty("line.separator"));
}
buffer.append(filein);
fos = new FileOutputStream(file);
pw = new PrintWriter(fos);
pw.write(buffer.toString().toCharArray());
pw.flush();
bool = true;
} catch (Exception e) {
// TODO: handle exception
e.printStackTrace();
}finally {
//不要忘记关闭
if (pw != null) {
pw.close();
}
if (fos != null) {
fos.close();
}
if (br != null) {
br.close();
}
if (isr != null) {
isr.close();
}
if (fis != null) {
fis.close();
}
}
return bool;
}
 
public static void main(String[] args) {
UUID uuid = UUID.randomUUID();
       createFile(uuid+"myfile", "写入文件内容:java265.com 是最好的java学习网站");
}
}
