本文实例讲述了java基于io流读取文件的方法。分享给大家供大家参考，具体如下：
public static void readfile(){
string pathstring = test.class.getresource("/simu").getfile();
try {
pathstring = urldecoder.decode(pathstring, "utf-8");
} catch (unsupportedencodingexception e1) {
e1.printstacktrace();
}
system.out.println(pathstring);
file file = new file(pathstring,"test.txt");
inputstream is = null;
try {
is = new fileinputstream(file);
} catch (exception e) {
e.printstacktrace();
}
bufferedreader br = new bufferedreader(new inputstreamreader(is));
stringbuffer sb = new stringbuffer("");
string b = "";
try {
while((b=br.readline())!=null){
sb.append(b).append("\n");
}
} catch (exception e) {
e.printstacktrace();
}
string bb = sb.tostring();
system.out.println(bb);
}
希望本文所述对大家java程序设计有所帮助。
