Question

Given two strings, append them together (known as "concatenation") and return the result. However, if the concatenation creates a double-char, then omit one of the chars. If the inputs are "Mark" and "Kate" then the output should be "markate". (The output should be in lowercase).

Comments

your questions are always making a confusion with data types.Make sure about correct ques statement and here is : if the last char of first word and first char of second word are same then omit one character.

try if(wordOne.charAt(wordOne.length()-1).toLowerCase() == wordTwo.charAt(0).toLowerCase())
print(wordOne.subString(0 to n-2).LowerCase()+wordTwo.toLowerCase())
else
print(wordOne.toLowerCase()+ wordTwo.toLowerCase())

Try this code

String str1; //First string
String str2; //Second string
if( str1.substring( str1.length()-1).equalsIgnoreCase( str2.substring(0,1)) )
                    System.out.println(  str1.concat( str2.substring(1, str2.length())).toLowerCase() );
                else
                    System.out.println(  str1.concat( str2) );
