In Java, string method concat is used for __________ strings.

In C++ struct myGrades { string class; char grade; };   Declare  myGrades as an array that can hold 5 sets of data and then set a class string in each position as follows: “Math” “Computers” “Science” “English” “History” and give each class a letter grade

Scala Programming: Given string str, write a Scala program to create a new string where "Scala " is added to the front of a given string. If the string already begins with "Scala", return the string unchanged. Otherwise, return the string after adding "Scala ". Test the function for two strings "Scala Programming" and "Programming" inside the main method.

1. Given a string of at least 3 characters as input, if the length of the string is odd return the character in the middle as a string. If the string is even return the two characters at the midpoint.   public class Class1 {    public static String midString(String str) { //Enter code here } }   -----------   2. Given an array of integers return the sum of the values stored in the first and last index of the array. The array will have at least 2 elements in it   public class Class1 {    public static int endSum(int[] values) { //Enter code here }    }   -----------   3. The method takes a string as a parameter. The method prints treat if the string is candy or chocolate (of any case, such as CaNdY) Otherwise print trick   import java.util.Scanner;   public class Class1 { public static void trickOrTreat(String str) { //Enter code here }    public static void main(String[] args) { Scanner s = new Scanner(System.in); trickOrTreat(s.nextLine()); } }

Exercise2: Thestrcmp(string1,string2)function comparesstring1to string2. It is a value returning function that returns a negative integer if string1 < string2, 0 if string1 == string2, and a positive integer if string1 > string2. Write a program that reads two names (last name first followed by a comma followed by the first name) and then prints them in alphabetical order. The two names should be stored in separate character arrays holding a maximum of 25 characters each. Use the strcmp() func- tion to make the comparison of the two names. Remember that 'a' < 'b', 'b' < 'c', etc. Be sure to include the proper header file to use strcmp().       Sample Run 1: Please input the first name Brown, George Please input the second name Adams, Sally The names are as follows: Adams, SallyBrown, George     Sample Run 2: Please input the first name Brown, George Please input the second name Brown, George The names are as follows: Brown, GeorgeBrown, GeorgeThe names are the same
