Replacing part of String one by one

I have string:

Apple, Banana, Strawberry; Lemon, Watermelon; Orange

When I try this:

if(meaning.contains(";"))
        {
            meaning=meaning.replace(";", "\n");
        }

Result:

Apple, Banana, Strawberry  
 Lemon, Watermelon  
 Orange

How to replace part of String one by one in order to replace ";" to "\n"+numStr?

1.Apple, Banana, Strawberry  
2.Lemon, Watermelon  
3.Orange

Didn't test it, but should work:

String[] lines = meaning.split(";");
StringBuilder res = new StringBuilder();
for (int i = 0, size = lines.length; i < size; i++) {
    res.append(i + 1).append(". ").append(lines[i]).append("\n");
}
res.toString();

You can use the following code. The trick is to use String.split() instead of String.replace().

if(meaning.contains(";"))
{
    StringBuilder builder = new StringBuilder();
    String[] meanings = meaning.split(";");
    for (int i = 0; i < meanings.length; i++) {
        builder.append(String.format(Locale.US, "%d. %s\n", i, meanings[i].trim()));
    }
    Log.d("meanings", builder.toString());
}

The result will print:

1.Apple, Banana, Strawberry
2.Lemon, Watermelon
3.Orange
