How to Replace Backslashes With Double in Java
The Java "replace" function lets you replace a number of characters with another set of characters. Use this function to replace a single backslash character with a double-backslash set of characters. The backslash character is an escape character, so use this function to replace backslashes that cause issues with databases or other programs that aren't parsing data properly.

Right-click the Java source code file that contains your backslash string. Click "Open With" and select your Java compiler.

2
Locate the string that contains the backslash. If you do not already have a string set up, the following code creates a string in Java:
string mystr = "code with \\ character";

Add the replace statement to the Java source code. The following code replaces the single backslash with a double backslash:
mystr.replace("\\", "\\\\");
Because the backslash is an escape character, you must use two backslashes for each single backslash you want in the string. Because you want two backslashes, you use four in the replace function.
