This method returns an int data-type which is based on the comparison between the two string. The order resulting from the compareTo() method is called “natural order”: Strings are sorted alphabetically; dates and times are sorted in chronological order. Java Comparable interface. This interface is found in java.lang package and contains only one method named compareTo(Object). To sort strings in alphabetical order in Java programming, you have to ask to the user to enter the two string, now start comparing the two strings, if found then make a variable say temp of the same type, now place the first string to the temp, then place the second string to the first, and place temp to the second string and continue. 2. If you are truly comparing Strings alphabetically to arrange them in order, use compareTo() method from Comparable interface in Java. Java Comparable interface is used to order the objects of the user-defined class. Using Built-in Functions: compareTo() of String Class and sort() of Arrays Class. I didn't want to paste the entire program. It also compare String based upon there value, and can be used to sort String alphabetically, if they are stored in List using Collections.sort() method. For that, we will use the String class compareTo() method.. compareTo() in Java. So we need to compare two strings alphabetically i.e character by character. Everything I've been able to find online (including the forums here) has suggested to use the Comparator class, or to put the strings into an array, and sort list- I really would like to stick with just the String class, and its methods please. compareTo() is a String class method which returns the lexicographical difference between two Strings(i.e compares two strings lexicographically). It provides a single sorting sequence only, i.e., you can sort the elements on the basis of single data member only. The order is based on return value (an integer number, say x) of the compareTo() method: obj1 > obj2 if x > 0. obj1 < obj2 if x < 0. obj1 equals obj2 if x = 0. Here’s how to sort names alphabetically in java or java program to sort names in an alphabetical order.

The following section will show you how to make a custom class comparable (and thus sortable). Java sort arraylist of objects – Comparable Example. Here is a quote from The Java Programming Language by Arnold, Gosling, ... not by their localized notion of order." String.compareTo(String) can be dangerous to use, depending on the context. Sort Strings. It also compare String based upon there value, and can be used to sort String alphabetically, if they are stored in List using Collections. CompareTo() is used to compare two strings lexicographically. Method syntax is: public int compareTo(T o); ). Comparable interface provides one method compareTo(T o) to implement in any class so that two instances of that class can be compared. Sorting string array alphabetically – String.compareTo We are going to write a program which will work ask for 2. sort() method.
