substring

问题 I have a method that extracts a certain substring from a string. This substring consists of the numbers in the string. Then this is parsed to an integer.

But I would like to automate it. My approach: String str =

问题 In my assignment it's forbidden to use collections and any arrays. We are allowed to use String Tokenizer but any other classes than String and System are not allowed. This solution has to work with any number of entries. I have a string which look like this : 1|Aaron|Peter|3063543030|john@gmail.com + "\n" 2|Buffet|Anthony|3063543030|john@gmail.com + "\n" 3|Dunty|Richard|3063543030|john@gmail.com For example, if the entry is 4|Doe|John|3063543030|john@gmail.com then the comparison will be
