Getting highest available string in java - string

Question

I want to get the highest available string value in java how can i achieve this.
Example: hello jameswangfron
I want to get the highest string "jameswangfron"
String Text = request.getParameter("hello jameswangfron");
Please code example.

Answer 1

public class HelloWorld{
public static void main(String []args){
String text = "hello jameswangfron";
String[] textArray = text.split(" ");
String biggestString = "";
for(int i=0; i<textArray.length; i++){
if(i==0) {
textArray[i].length();
biggestString = textArray[i];
} else {
if(textArray[i].length()>textArray[i-1].length()){
biggestString = textArray[i];
}
}
}
System.out.println("Biggest String : "+biggestString);
}
}
And it shows the output as
Biggest String : jameswangfron

Answer 2

Maybe this will be easyer to understand
public class HelloWorld {
public static void main(String[] args) {
System.out.println(StringManipulator.getMaxLengthString("hello jameswangfron", " "));
}
}
class StringManipulator{
public static String getMaxLengthString(String data, String separator){
String[] stringArray = data.split(separator);
String toReturn = "";
int maxLengthSoFar = 0;
for (String string : stringArray) {
if(string.length()>maxLengthSoFar){
maxLengthSoFar = string.length();
toReturn = string;
}
}
return toReturn;
}
}
But there is a catch. If you pay attention to split method from class String, you will find out that the spliter is actually a regex. For your code, i see that you want to separate the words (which means blank space). if you want an entire text to search, you have to pass a regex.
Here's a tip. If you want your words to be separated by " ", ".", "," (you get the ideea) then you should replace the " " from getMaxLengthString method with the following
"[^a-zA-Z0-9]"
If you want digits to split up words, simply put
"[^a-zA-Z]"
This tells us that we use the separators as anything that is NOT a lower case letter or upper case letter. (the ^ character means you don't want the characters you listed in your brackets [])
Here is another way of doing this
"[^\\w]"
\w it actually means word characters. so if you negate this (with ^) you should be fine
