Removing whitespace from strings in Java

Question

I have a string like this:

mysz = \"name=john age=13 year=2001\";

I want to remove the whitespaces in the string. I tried trim()

When using st.replaceAll("\\s+","") in Kotlin, make sure you wrap "\\s+" with Regex:

"myString".replace(Regex("\\s+"), "")
