文件创建读取（自用勿点）
小时候控制台游戏所用的工具类，有毒哈哈哈哈：
1、txt传记记录文件：
package com.yy.diabio.v1.utils;
import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.FileWriter;
import java.io.IOException;
import java.io.PrintWriter;
/**
* 传记
* @author Administrator
*
*/
public class Biography {
/**
* 读一行写一行
* @param path
*/
public static void readLineAndWrite(String path,String pathout){
try {
File file = new File(path);
String expath= path.replace(".", "_re.");
expath=expath.replaceAll("fileImp", "fileExp");
System.out.println(expath);
//int index =path.lastIndexOf(".");
//File expFile = new File("D:/scc0511_others_r.net");
File expFile = new File(expath);
BufferedReader br = new BufferedReader(new FileReader(file));
PrintWriter out = new PrintWriter(new BufferedWriter(
new FileWriter(expFile, true)));
String line = null;
while ((line = br.readLine()) != null) {
out.println(line);
}
if (br != null) {
br.close();
}
if (out != null) {
out.close();
}
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
/**
* 书写append，新建时会刷新或者创建新的
* @param path
* @param pathout
*/
public static void writeBioGraPhy(String msg){
String path=getPath();
File file = new File(path);
if(!file.exists()){
try {
file.createNewFile();
} catch (IOException e) {
e.printStackTrace();
}
}
PrintWriter out =null;
try {
out = new PrintWriter(new BufferedWriter(
new FileWriter(file, true)));
out.println(msg);
} catch (IOException e) {
e.printStackTrace();
}finally{
out.flush();
}
}
/**

*/
public static String getPath() {
//构造时获取到项目的物理根目录
//String project_root = this.getClass().getResource("/").toString().replace("file:/", "");

String path=project_root+"/src"+"/Biography.txt";
//path=project_root+"/Role.txt";
return path;
}*/
}
2、存档对象记录工具类：
package com.yy.diabio.v1.utils;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;
import com.yy.diabio.v1.role.Role;
public class ObjStreamUtil {
//1.创建目标路径
//（一）先写入对象
public static void saveRole(Role role){
File file = null;
String path = getPath();
file = new File(path);
if(!file.exists()){
try {
file.createNewFile();
} catch (IOException e) {
e.printStackTrace();
}
}
//2.创建流通道
FileOutputStream fos=null;
//3.创建对象输出流
ObjectOutputStream objOP=null;
try {
System.out.println(file);
fos = new FileOutputStream(file);
objOP = new ObjectOutputStream(fos);
objOP.writeObject(role);
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}finally{
if(objOP!=null){
try {
objOP.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
}
//再读取对象
public static Role readRole(){
File file = null;
String path = getPath();
file = new File(path);
if(!file.exists()){
try {
file.createNewFile();
} catch (IOException e) {
e.printStackTrace();
}
}
FileInputStream fis=null;
ObjectInputStream objIP=null;
Role role =null;
try {

} catch (FileNotFoundException e) {
} catch (IOException e) {
} catch (ClassNotFoundException e) {
}catch (Exception e) {
}finally{
if(objIP!=null){
try {
objIP.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
return role;
}
public static String getPath() {
//构造时获取到项目的物理根目录
//String project_root = this.getClass().getResource("/").toString().replace("file:/", "");
String project_root=ReadPropertiesUtil.class.getResource("/").toString().replace("file:/", "");

return path;
}
/**

/* public static String getPath() {

//path=project_root+"/Role.txt";
return path;
}*/
}
3、properties记录类：
package com.yy.diabio.v1.utils;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.io.InputStream;
import java.util.Enumeration;
import java.util.Iterator;
import java.util.Map;
import java.util.Properties;
public class propertiesBath {
//初始化properties
public static void main(String[] args) {
Properties pro = new Properties();
try {
InputStream inStr = ClassLoader.getSystemResourceAsStream("Role.properties");
pro.load(inStr);
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
//返回所有的属性名，即键名。
//propertyNames(),返回属性列表中所有键的枚举
Enumeration enu2=pro.propertyNames();
while(enu2.hasMoreElements()){
String key = (String)enu2.nextElement();
System.out.println(key);
}
//返回所有的属性值。
//Properties 继承于 Hashtable，elements()是Hashtable的方法，返回哈希表中的值的枚举。
Enumeration enu=pro.elements();
while(enu.hasMoreElements()){
String key = (String)enu.nextElement();
System.out.println(key);
}
//返回所有的属性（属性名，属性值）。
//Properties 继承于 Hashtable，entrySet()是Hashtable的方法，
//返回此 Hashtable 中所包含的键的 Set 视图。此 collection 中每个元素都是一个 Map.Entry
Iterator it=pro.entrySet().iterator();
while(it.hasNext()){
Map.Entry entry=(Map.Entry)it.next();
Object key = entry.getKey();
Object value = entry.getValue();
System.out.println(key +":"+value);
}
}
}

//sors first Random Skill,just for fun ,hah ,its dosent metter
