关于Java的字符转换

Java类型的字符转换方法是什么?不用急，下面一起和小编来学习学习吧!

利用字节流FileOutputStream写文文本文件

import utStream;

import OutputStream;

import ception;

OutputStream obj = FileOutputStream("文件名称");

String array ="字符串";

String [] aa = ytes();

e(aa,0,th());

e();

利用字符流BufferedReader读文本文件

import Reader;

import eredReader;

import ception;

FileReader fr = new FileReader("文件名称");

BufferedReader br = new BufferedReader(fr);

Line();

e();

e();

利用BufferedWriter写文本文件

import Writer;

import eredWriter;

import ception;

FileWriter fw = new FileWriter("文件名称");

BufferedWriter bw = new BufferedWriter(fw);

er("字符串");

h();

e();

利用字节流DateInputStream读二进制文件

import InputStream;

import InputStream;

FileInputStream fis = new FileInputStream("文件名称");

DateInputStream dis = new DateInputStreamI(fis);

Int();

Byte();

e();

利用字节流DateOutputStream写二进制文件

import OutputStream;

import OutputStream;

FileOutputStream fop = new FileOutputStream("文件名称");

DateOutputStream dop = new DateOutputStream(fop);

e(1);

e();

JDBC 应用程序的结构

import xception;

import cetion;

import erManager;

import ement;

import ltSet;

try{

ame("OdbcDriver");

}catch(ClassNotFoundException e){

tln(e);

}

try{

String aa = "jdbc:odbc:test";

Connection con = onnection(aa);

Statement s = teStatement();

ResultSet rs = uteQuery("查询语句");

while(())

e()

e();

e();

} catch(SQLException ee){

t(ee);

}
