Question

JAVA 将一个OBJECT类型的二维数组存到TXT文件里，然后再读取

Object[][] tableData = { new Object[] { "李清照", 29, "女" },
new Object[] { "苏格拉底", 56, "男" },
new Object[] { "李白", 35, "男" },
new Object[] { "弄玉", 18, "女" },
new Object[] { "虎头", 2, "男" } };
现在有这么一个数组，我想用FileOutputStream输出到一个txt文档中，每次写到fileoutput.write()的时候总是报错，麻烦高手帮写一个完整的语句，谢谢

Answer 1

public class Test{

public static void main(String args[])
{
Object[][] tableData = { new Object[] { "李清照", 29, "女" },
new Object[] { "苏格拉底", 56, "男" },
new Object[] { "李白", 35, "男" },
new Object[] { "弄玉", 18, "女" },
new Object[] { "虎头", 2, "男" } };

try {
File f=new File("D:/test.txt");
FileOutputStream out=new FileOutputStream(f);
for(Object[] o:tableData){
for(Object obj:o)
{
byte [] b=obj.toString().getBytes();
out.write(b,0,b.length);
out.write(" ".getBytes());
}
out.write("\r\n".getBytes());
}
out.flush();
out.close();
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
