Here are some example Java codes on how to Left Pad String With Zeroes to guarantee the length of a String. For example, if there are only 3 characters in a String and we wish to have it 10 characters long, we need to pad 7 zeroes to the left of the String.
There are cases when we need to Convert a Java Integer To Fixed Length String. The logic should append a certain character, usually blank or zero, to fill the missing characters when the number of digits is less than the required number of characters.
The split method of the Java String class splits the given string into substrings given a delimiter. The result is an array of String. We may specify the maximum number of items returned by using specifying the limit. Java String Split Limit examples will be shown below.
The String.split() method splits a String into an array of substrings given a specific delimiter. If we know that each substring represents a number or an integer, we may prefer to convert the output of String.split() into an array of integer.
Sometimes it is not appropriate to split a String using whitespaces. For example, when items are expected to be phrases. Usually, it is more useful to select a special character to split a String. Here is an example on how to Split a Java String using pipe ( | ) as delimiter.
A common programming scenario in Java is to Split Strings using space or whitespaces as separators. This is useful, for example, when we want to retrieve all the words in a text document. The whitespaces are the markers that separates each word. Split is very powerful because you can specify the delimiter via regular expression. It can save a lot of time because of the power of regex.
