[英]PrintWriter to print on next line
I have the following code to print a string(from a ResultSet) to a text file: 我有以下代码将字符串(从ResultSet)打印到文本文件:
PrintWriter writer = new PrintWriter(new FileOutputStream(file, false));
while(RS.next()) {
writer.write(RS.getString(1)+"\n");
}
I put a "\\n" in the write statement in hopes that it will print each row on a different line, but it failed. 我在write语句中加了一个“\\ n”,希望它会在不同的行上打印每一行,但它失败了。 The txt file currently prints out like so, with row# being a different row in the ResultSet:
txt文件当前打印出来,因为row#是ResultSet中的另一行:
row1row2row3row4row5 row1row2row3row4row5
I want it to print out like: 我希望它打印出来像:
row1 ROW1
row2 2行
row3 ROW3
row4 ROW4
row5 ROW5
... ...
您应该使用println
在每行之后打印换行符:
writer.println(RS.getString(1));
You can use PrintWriter#println() method instead. 您可以使用PrintWriter #println()方法。
From API: 来自API:
Terminates the current line by writing the line separator string.
通过写行分隔符字符串来终止当前行。 The line separator string is defined by the system property line.separator, and is not necessarily a single newline character ('\\n').
行分隔符字符串由系统属性line.separator定义,不一定是单个换行符('\\ n')。
Also this should work as well. 这也应该有效。
writer.write(RS.getString(1)+ System.getProperty("line.separator"));
Use, in the statement. 在声明中使用。 For example:
例如:
writer.print("1"+"<br/>");
writer.print("2"+"<br/>");
