The First and Last program
The program in Java, where comments are used to explain each line is as follows:
//This defines the function
public static String firstAndLast(String str){
//This gets the first character
String first=str.substring(0,1);
//This gets the last character
String last=str.substring(str.length()-1);
//Ths returns the first and last characters
return first+last;
}
