How do you sort letters in java?

Answer 1

Let us assume by "alphabet letters arrays" you mean you have an array of chars.

char[] letters = //some character array

Arrays.sort(letters);

// Letters is now sorted.

// Note that letters will be sorted according to the ASCII values

// of the chars. This means that all capital letters will be sorted

// before lower case. ('Z' will come before 'a')

Answer 2

{

char[] letters; // assume this is filled with the letters you want to sort

Arrays.sort(letters);

// letters is now sorted

}
