"如何从字符串中删除回车符"

Question

String s ="SSR/DANGEROUS GOODS AS PER ATTACHED SHIPPERS
/DECLARATION 1 PACKAGE

NFY
/ACME CONSOLIDATORS"

Answer 1

Java's String.replaceAll in fact takes a regular expression. You could remove all newlines with:

s = s.replaceAll("\\n", "");
s = s.replaceAll("\\r", "");

But this will remove all newlines.

Note the double \\ 's: so that the string that is passed to the regular expression parser is \\n .

You can also do this, which is smarter:

s = s.replaceAll("\\s{2,}", " ");

This would remove all sequences of 2 or more whitespaces, replacing them with a single space. Since newlines are also whitespaces, it should do the trick for you.

Answer 2

试试这个代码：

s = s.replaceAll( "PACKAGE\\s*NFY", "PACKAGE NFY" );

Answer 3

s = s.replaceAll("[\\n\\r]", "");

Answer 4

Have you tried a replace function? Something in the lines of:

youString.Replace("\r", "")

Answer 5

string = string.replace(/\s{2,}/g, ' ');
