How do I sort an array of strings? [duplicate]

Question

I'm new to Java, and I wrote code that sorts numbers, but I was trying to convert it to sort strings and it won't work. What is the most basic way of sorting strings in alphabetical order?

Where/how would I initialize Arrays.sort()?

Arrays is a Util class in Java, Just import it and you can use its methods. No need to init that, all methods are in static

Java Strings are Comparables, meaning they have a compareTo method which can be used to compare two such objects. a.compareTo(b) will return a negative value if a is logically less than b, a positive value if a is greater than b or 0 if they are equal.

So you can keep your entire logical flow and just change the comparison check - instead of if (name[y] > name[y+1] ) you'd need to use if (name[y].compareTo(name[y+1]) > 0 ).
