删除空格 [英] Removing blank spaces
问题描述
您好，
以下是java程序的一部分。
我正在读取db2中存储过程返回的结果集并将其写入文件。
我已经使用DataOutputStream dos将读取对象写入文件。
int totRows = 0;
System.out.println（"结果集+（count-1）+写入文件..."）;
while（rs.next（））{
totRows ++;
for（int i = 1; i< = col; i ++）{
Object o = rs.getObject（i）;
dos .writeChars（String.valueOf（o））;
dos.writeUTF（" \t"）;
}
dos。 writeUTF（\\\\ nn）;
}
System.out.println（totRows +" rows written ..."）;
输出为：文件内容r类似
TABLENAMETABLECOUNT
CUSTOMERINFOTABLE 6666
。 ...... 。
......
n等等
我希望它看起来像
TABLENAME TABLECOUNT
CUSTOMERINFOTABLE 6666
.............
这次至少得到一些帮助！
Hello,
Following is a part of java program.
I am reading Result Set returned by Stored Procedure in db2 and writing that into a file.
I have used DataOutputStream dos to write read object into file.
int totRows = 0;
System.out.println("Result Set"+(count-1)+" Writing into file...");
while (rs.next()) {
totRows++;
for (int i = 1; i <= col; i++) {
Object o = rs.getObject( i);
dos.writeChars(String.valueOf(o));
dos.writeUTF("\t");
}
dos.writeUTF("\r\n");
}
System.out.println(totRows+" rows written...");
Output is : File contents r like
T A B L E N A M E T A B L E C O U N T
C U S T O M E R I N F O T A B L E 6666
........
......
n so on
I want it to look like
TABLENAME TABLECOUNT
CUSTOMERINFOTABLE 6666
.............
Expect to get some help atleast this time!

我不认为问题是由writeChars方法引起的，而是对象的String.valueOf是放入空格的那个。 （数字似乎没有发生？）。您可能需要先拆分输出：
I do not think the problem is caused by the writeChars method but rather the String.valueOf for your objects is the one that is putting in the spaces. (It does not seem to be happening for numbers?). You may need to split the output first:
forx解决方案！
它适用于字符串......但不适用于数字......
你能告诉我吗？wat可以完成4 dat吗？
Hi,
Thanx for the solution!
Its working properly for strings... but not for numbers...
can u tel me y so?wat can be done 4 dat?
