Answer 2

While you could escape the regular expression to String.split with the somewhat surprising

String str = "a\\b\\c";
str.split("\\\\");

it is also possible to compile a Pattern with Pattern.LITERAL and then use Pattern.split(CharSequence) like

String str = "a\\b\\c";
Pattern p = Pattern.compile("\\", Pattern.LITERAL);
String[] arr = p.split(str);
System.out.println(Arrays.toString(arr));

Which outputs

[a, b, c]

Answer 3

Simply use \\n inside the string where need. No method need to split.

1. "\\" special character in java. It is use to skip a character. Such as String s = "I am a \\"Student\\" of a University!"; Hear Double cote is not allow without using "\\".
2. We can not use "\\" single in a string. String s = "I am a \\ Student of a University!"; Hear "\\" will make an Err.

3. No method need to split using "\\" Simply use "\\n" Where you Need.

   Or use another character with it like this

    String s = "Thir is a Tiger.\\'I like it very nuch!\\'I it a pet!"; String s2[] = s.split("\\'"); for (int i = 0; i < s2.length; i++) { System.out.println(i+" value "+s2[i]); } 

Answer 4

 String s = "light\\hello\\text.txt";
    String s3[] = s.split(Pattern.quote("\\"));
    for (int i = 0; i < s3.length; i++) {
        System.out.println(i+" value "+s3[i]);
}
