How to get index of Escape Character in a String?

String test="1234\567890";
System.out.println("Result : "+test.lastIndexOf("\\"));

Result i get: -1

Result i need: 4

Answer 1

Your original String doesn't contain \. Which means you are searching something which does not exist. Inorder to add \ to your string. You have to escape while adding

String test="1234\\567890";
System.out.println("Result : "+test.lastIndexOf("\\"));

Should work.

In your case look at the last line in the table.
