Android - Split the paragraphs in a string

I have a long string which holds the tags p /p for paragraphs. This is html string to be placed in web view.

I need to split the paragraphs into two and assign each one to a string. Example:

String A:

<p> I have an orange <\p>
<p> I have an apple <\p>
<p> I have a banana <\p>
<p> I have a fruit <\p>
<p> I love to go bike riding<\p>
<p> Hello how are you <\p>

Now I need to split the paragraphs into 2 and assign to 2 different strings:

String B should have:
<p> I have an orange <\p>
<p> I have an apple <\p>
<p> I have a banana <\p>

String C should have:

<p> I have a fruit <\p>
<p> I love to go bike riding<\p>
<p> Hello how are you <\p>

how can I achieve it?

I just assume you mean </p> instead of <\p> as the closing tag.

Assuming you always have this structure, with <p>...</p> following <p>...</p> and nothing inbetween, you can just do this:

String A = "<p> I have an orange </p>"
    + "<p> I have an apple </p>"
    + "<p> I have a banana </p>"
    + "<p> I have a fruit </p>"
    + "<p> I love to go bike riding</p>"
    + "<p> Hello how are you </p>";

String[] paragraphs = A.split("</p>");
final int halfParagraphs = (int) Math.ceil((double) paragraphs.length / 2);

StringBuilder bBuilder = new StringBuilder();
StringBuilder cBuilder = new StringBuilder();
for(int idxB = 0; idxB < halfParagraphs; idxB++) {
    int idxC = idxB + halfParagraphs;
    // split removes the separator, so we need to append it again
    bBuilder.append(paragraphs[idxB]).append("</p>");
    if (paragraphs.length > idxC) {
        cBuilder.append(paragraphs[idxC]).append("</p>");
    }
}
String B = bBuilder.toString();
String C = cBuilder.toString();

I also assumed you want String B to hold more values if the number cannot be evenly distributed. This is certainly not the cleanest solution, but it works without adding an extra character in the Text.

This is the code. Note where I added the § character in strA, in order to split the string:

final String strA = "<p> I have an orange </p><p> I have an apple </p><p> I have a banana </p>§<p> I have a fruit </p><p> I love to go bike riding</p><p> Hello how are you </p>";
final String arr[] = strA.split("§");
final String strB = arr[0]; // Contains: "<p> I have an orange </p><p> I have an apple </p><p> I have a banana </p>"
final String strC = arr[1]; // Contains: "<p> I have a fruit </p><p> I love to go bike riding</p><p> Hello how are you </p>"
