Removing the last line of a String

#1

Hey guys

This is probably a very simple question, but i can’t seem to get the just of it.

String sentence = “Hello\nWorld”;
now i want to remove the last line of the string ("\nWorld");

i.e. sentence -= "\n"
but then it says
"operator - cannot be applied to java.lang.String,java.lang.String"

#2

indexOf and substring

I somewhat disagree with the previous answer. You could combine indexOf() and substring() but I think split() is much better suited since you will get a String[] array containing all the parts you were after.

Naturally this heavily depends on what the final goals are but since that wasn’t included…
