Splitting a String in Java using a delimiter

In this post of Splitting a String in Java using a delimiter We will learn how to split a string based on provided delimiter.In many applications, you get data in a text file that is separated by a comma (,) symbol or a pipe (|) symbol or a tab icon (/ t) or can be any delimiter. Now, if you want to make a quick split around that different symbol, you can easily do this by using the split () method of String class. In this post we are going to see a java program to split a string.

In this java program ,We are going see how to split input string based on delimiter like colon(:) or pipe(|) or comma(,) or tab(\t) etc..
But you may modify this program to split your input string for any other delimiter as per your choice.
