复制代码代码如下:
tentar {
// 方法一
BufferedReader br = new BufferedReader(new FileReader(novo Arquivo(
"D://1.xls")));
//StringBuilder bd = new StringBuilder();
StringBuffer bd = new StringBuffer();
enquanto (verdadeiro) {
String str = br.readLine();
if (str == nulo) {
quebrar;
}
System.out.println(str);
bd.append(str);
}
close();
//System.out.println(bd.toString());
// 方法二
InputStream é = new FileInputStream(new File("d://1.xls"));
byte b[] = novo byte[Integer.parseInt(new File("d://1.xls").length()
+ "")];
é.ler(b);
Sistema.out.write(b);
System.out.println();
é.close();
// 方法三
Leitor r = new FileReader(new File("d://1.xls"));
char c[] = new char[(int) new File("d://1.xls").length()];
ler(c);
Stringstr = nova String(c);
System.out.print(str);
fechar();
