It provides a convenient way to work with text data, but there are many tips and tricks that can help you get the most out of it. In this blog, we’ll cover 10 unique tips and tricks for working with Java’s String class that you may not have seen before.
Tip 1:
Using String.join() to concatenate strings One of the simplest and most powerful methods in the String class is join(). It can be used to concatenate strings with a specified delimiter. For example:
Tip 2:
Using String.repeat() to repeat a string Another handy method in the String class is repeat(). It can be used to repeat a string a certain number of times. For example:
Tip 3:
