Using regexes with "\s" and doing simple string. split()'s will also remove other whitespace - like newlines, carriage returns, tabs.
strip()—Remove Leading and Trailing Spaces. The str. strip() method removes the leading and trailing whitespace from a string.
In Java, we can use regex \\s+ to match whitespace characters, and replaceAll("\\s+", " ") to replace them with a single space.
The tools sed or tr will do this for you by swapping the whitespace for nothing
sed 's/ //g'
tr -d ' '
Example:
$ echo " 3918912k " | sed 's/ //g' 3918912k If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
