 Please complete the java code below.    public class Lab11 {          //This function converts the contents of the array of Strings into a single String with         //appropriate spaces and returns it.         //For example if String[] s = {"I", "am", "doing", "good."}; is an input to the function         //The result is a String, I am doing good.          public static String concatenateStrings(String[] strArray){                  //Create a String variable <concatenatedStr> and initialize it to "";                 //-->                  //Implement a for loop where the loop variable <i> goes from the 0 to the length of <strArray> (not included)                 for(int i=0; i < strArray.length;i++)                 {                         //Concatenate the string at index <i> of <strArray> to <concatenatedStr>                         concatenatedStr+= " " + ???;                 }                  //return <concatenatedStr>                 //-->         }           //This function calculates the sum of the array of integers and returns it.         //For example if int[] s = {1, 2, 3}; is an input to the function         //The result is an Integer, 6          public static double findSumOfArray(int[] intArray)         {                 //Create an integer variable <sum> and initialize it to 0;                 //-->                  //Implement a for loop where the loop variable <i> goes from the 0 to the length of <intArray> (not included)                 for(int i=???; i < ???; i++)                 {                         //Add the integer at index <i> of <intArray> to <sum>                         //-->                 }                  //return <sum>                 //-->         }           //The main method begins here.

Here you go :)

//Lab11 class

public class Lab11 {

   public static String concatenateStrings(String[] strArray) {
       String concatenatedStr = "";
       for (int i = 0; i < strArray.length; i++) {
           concatenatedStr += " " + strArray[i];
       }
       return concatenatedStr;
   }

   public static double findSumOfArray(int[] intArray) {
       int sum = 0;
       for (int i = 0; i < intArray.length; i++) {
           sum += intArray[i];
       }
       return sum;
   }

   public static void main(String[] args) {
       String[] brokenString = { "I", " was", "broken", "and", "you", "fixed",
               "me." };
       int[] tenNaturalNos = new int[10];
       for (int i = 0; i < 10; i++) {
           tenNaturalNos[i] = i + 1;
       }
       System.out.println("The array of Strings : ");
       for (int i = 0; i < brokenString.length; i++) {
           System.out.println(brokenString[i]);
       }

       System.out.println("The array of Integers : ");
       System.out.println("The array of Natural numbers : ");
       for (int i = 0; i < tenNaturalNos.length; i++) {
           System.out.println(tenNaturalNos[i]);
       }
       System.out.println("The array of Strings now becomes : "
               + concatenateStrings(brokenString));
       System.out.println("The sum of the integers in the array is : "
               + findSumOfArray(tenNaturalNos));

   }
}
