Create a method called nicknames that passes an array as a parameter. Inside the method initialize it to hold 5 names of your ch
Gre4nikov [31]
<h2>Answer:</h2>

    //======METHOD DECLARATION=========//          

    //method name: nicknames                                          

    //method return type: void                                            

    //method parameter: an array reference                    

    public static void nicknames(String [] names){      

       //initialize the array with 5 random names              

       names = new String[] {"John", "Doe", "Brian", "Loveth", "Chris"};

       //using an enhanced for loop, print out the elements in the array

       for(String n: names){

           System.out.print(n + " ");

       }

       

    }

<h2>Explanation:</h2>

The program is written in Java. It contains comments explaining important parts of the code. Kindly go through these comments.

A few things to note.

i. Since the method does not return any value, its return type is <em>void</em>

ii. The method is made public so that it can be accessible anywhere in and out of the class the uses it.

iii. The method is made static since it will most probably be called in the static main method (at least for testing in this case)

iv. The method receives an array of type <em>String </em>as parameter since the names to be stored are of type <em>String</em>.

v. The format of initializing an array manually should follow as shown on line 7. The <em>new</em> keyword followed by the array type (String), followed by the square brackets ([]) are all important.

vi. An enhanced for loop (lines 9 - 11) is a shorthand way of writing a for loop. The format is as follows;

=> The keyword <em>for</em>

=> followed by an opening parenthesis

=> followed by the type of each of the elements in the array. Type String in this case.

=> followed by a variable name. This holds an element per cycle of the loop.

=> followed by a column

=> followed by the array

=> followed by the closing parenthesis.

=> followed by a pair of curly parentheses serving as a block containing the  code to be executed in every cycle of the loop. In this case, the array elements, each held in turn by variable n, will be printed followed by a space.

A complete code and sample output for testing purposes are shown as follows:

==================================================

public class Tester{

    //The main method

    public static void main(String []args){

       

       String [] names = new String[5];

       nicknames(names);

    }

   

  //The nicknames method

    public static void nicknames(String [] names){

       names = new String[] {"John", "Doe", "Brian", "Loveth", "Chris"};

       for(String n: names){

           System.out.print(n + " ");

       }

       

    }

}

==================================================

<h2>Output:</h2>

John Doe Brian Loveth Chris

<em>NB: To run this program, copy the complete code, paste in an IDE or editor and save as Tester.java</em>

Write a loop to print all elements in hourly_temperature. Separate elements with a -&gt; surrounded by spaces. Sample output for
kaheart [24]

Answer:

Following are the code to this question:

hourly_temperature = [90, 92, 94, 95]#defining a list that holds values

c= 0#defining a variable c

for temp in hourly_temperature:#defining a for loop to count list values

   c+= 1#defining c variable to increment the value of c

   for index,temp1 in enumerate(str(temp)):#defining for loop for spacing the list value

       if index == len(str(temp))-1 and c!= len(hourly_temperature):#defining if block that checks the length of list

           print(temp1,'->',end=' ')#print value

       elif c == len(hourly_temperature) and index == len(str(temp)) - 1:#defining elif block that checks the length of list

           print(temp1, end=' ')#print value

       else:#defining else block

           print(temp1, end='')#print value

Output:

90 -> 92 -> 94 -> 95  

Explanation:

In the above-given code, a list "hourly_temperature" is declared, in which an integer variable c is declared, that holds an integer value that is equal to 0, and two for loop is declared, and in the first loop is used for count list value, and inside the for loop is uses enumerate method to assigns an index for each item and use the conditional statement to check each list value and provide space in each element value.
