關於Java的字元轉換

Java型別的字元轉換方法是什麼?不用急，下面一起和小編來學習學習吧!

利用位元組流FileOutputStream寫文文字檔案

import utStream;

import OutputStream;

import ception;

OutputStream obj = FileOutputStream("檔名稱");

String array ="字串";

String [] aa = ytes();

e(aa,0,th());

e();

利用字元流BufferedReader讀文字檔案

import Reader;

import eredReader;

import ception;

FileReader fr = new FileReader("檔名稱");

BufferedReader br = new BufferedReader(fr);

Line();

e();

e();

利用BufferedWriter寫文字檔案

import Writer;

import eredWriter;

import ception;

FileWriter fw = new FileWriter("檔名稱");

BufferedWriter bw = new BufferedWriter(fw);

er("字串");

h();

e();

利用位元組流DateInputStream讀二進位制檔案

import InputStream;

import InputStream;

FileInputStream fis = new FileInputStream("檔名稱");

DateInputStream dis = new DateInputStreamI(fis);

Int();

Byte();

e();

利用位元組流DateOutputStream寫二進位制檔案

import OutputStream;

import OutputStream;

FileOutputStream fop = new FileOutputStream("檔名稱");

DateOutputStream dop = new DateOutputStream(fop);

e(1);

e();

JDBC 應用程式的結構

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("查詢語句");

while(())

e()

e();

e();

} catch(SQLException ee){

t(ee);

}
