Using String class:

char[] words = { 'c', 'd', 'f', 'h', 'j' };
String str = new String(words);
words = (str.substring(0, Math.min(1, words.length)) + str.substring(Math.min(1 + 1, words.length))).toCharArray();

Running in jshell:

jshell> char[] words = { 'c', 'd', 'f', 'h', 'j' };
words ==> char[5] { 'c', 'd', 'f', 'h', 'j' }

jshell> String str = new String(words);
str ==> "cdfhj"

jshell> words = (str.substring(0, Math.min(1, words.length)) + str.substring(Math.min(1 + 1, words.length))).toCharArray();
words ==> char[4] { 'c', 'f', 'h', 'j' }
