writing '\t' '\n' etc. characters in a file like a string_?
hi there i am trying to write a code that generates automatically code and writes in a file.so the problem is when i try to write '\t' '\n' etc. characters i am facing with problems.
FileOutputStream fos2 = new FileOutputStream("...\\PersonalList.java");
PrintStream pr2 = new PrintStream(fos2);
for (Iterator<String> itr = name.iterator(); itr.hasNext();) {
i++;
s_str = itr.next开发者_Go百科();
if(i==counter)
pr2.print('"' + s_str.toUpperCase() + '"' + ");\n");
else
pr2.print('"' + s_str.toUpperCase() + '\t' + '"' + '+');
}
and my goal is writing a code for example "pr.println("var1\t" + "var2\t") into another file and when i compile that file it would create a text file, so when i look at my .txt file i should see "NAME (here must be white space character) LAST_NAME". but in '\t' character it writes pr.println("var1" + "var2"). i hope i explain my work correctly. : ) and i appreciated if you could help me.
It's not really clear what you mean, but I suspect you're just trying to escape the backslash:
pr2.print('"' + s_str.toUpperCase() + "\\t\"+");
(I've taken the liberty of combining all the characters you've got at the end into a single string, which means we need to escape the double quote as well, hence the \"
.)
The backslash character is a special character used to escape things like tabs (\t
), newlines (\n
), etc. So if you want to print a backslash, you have to type \\
.
In your particular case, you want to print out "\\t"
.
