Java Include delimiter into splitted array

Question

Is there a way in Java in which I can split a string into an array, but with the delimiter? For example normally I would have a String such as this in the text editor I am building:

String content = "What time\nWhat day\nWhat month\n\n\nAsdf"

And if I called the split method with the \n delimiter like this:

content.split("\n")

I would get a String[] array like this:

{"What time", "What day", "What month", "Asdf"}

But I want this:

{"What time", "\n", "What day", "\n", "What month", "\n", "\n" ....}

Is there any built-in property I need to set or do I have to implement this from scratch.

Have you tried adding an extra slash in the variable? e.g. 'What time\\n' — Poriferous, Jul 22 '15 at 23:47

There are many ways, one of them is: "after splitting using separator, add separator after each element except last one like this":

public static void main(String[] args) {
        String content = "sawad";
        String seperator="a";
        String[] s=content.split(seperator);
        int length=s.length;
        System.out.println(length);
        for(int i=0;i<s.length;i++)
        {
            System.out.println(s[i]);
        }


        String [] d=new String[(length * 2) -1];
        for(int i=0;i<s.length;i++)
        {
            d[2*i]=s[i];
            if(i<length-1)
                d[2*(i+1) -1]=seperator;
        }

        System.out.println("------");
        System.out.println(d.length);
        for(int i=0;i<d.length;i++)
        {
            System.out.print(d[i]);
        }
    }
