mydate.replaceAll("\\\\","#");

Will replace it. The reason you need four backslashes is that the first argument is a regular expression, which expects backslashes to be escaped, and then java expects the backslashes in strings to be escaped as well, leading to the four backslashes. Alternatively you could just declare your string like

String mydate = "jan\\10" ;

and have it print normally.

String myDate = @"jan\10";
String newDate = myDate.replace('\\', '#');

String str = "hello\\world";
System.out.println(str.replaceAll("\\\\", "@"));

output:

hello@world

You must to shield slash: String mydate = "jan\\10" ;

If you want to replace this char:

mydate = mydate.replace("\\", "#");//result is jan#10
