Write code to take a String input from the user, then print the first and last letters of the string on one line. Sample run: En
Ainat [17]
<h2>Answer:</h2>

//import the Scanner class to allow for user input

import java.util.Scanner;

//Begin class definition

public class FirstAndLast{

   //Begin the main method

    public static void main(String []args){

       

       

       //****create an object of the Scanner class.

       //Call the object 'input' to receive user's input

       //from the console.

       Scanner input = new Scanner(System.in);

       

       //****create a prompt to tell the user what to do.

       System.out.println("Enter the string");

       

       //****receive the user's input

       //And store it in a String variable called 'str'

       String str =  input.next();

       

       //****get and print the first character.

       //substring(0, 1) - means get all the characters starting

       //from the lower bound (index 0) up to, but not including the upper

       //bound(index 1).

       //That technically means the first character.

       System.out.print(str.substring(0,1));

       

       //****get and print the last character

       //1. str.length() will return the number of character in the string 'str'.

       //This is also the length of the string

       //2. substring(str.length() - 1) - means get all the characters starting

       // from index that is one less than the length of the string to the last

       // index (since an upper bound is not specified).

       // This technically means the last character.

       System.out.print(str.substring(str.length()-1));

       

       

       

    }  // end of main method

   

} //end of class definition

Which of the following is not a benefit of normalization?
mixer [17]

Answer:

The answer is option (4) Maximize redundancy as normalization minimizes redundancy of data.

Explanation:

Normalization of databases leads to minimization of data redundancy in databases. It doesn't maximize data redundancy. Data redundancy leads to wastage of resources. Normalization of databases minimizes insertion anomolies. Normalization of databases minimizes deletion anomolies. Normalization of databases minimizes updation anomolies.  So , the answer to the question is option (4) maximize redundancy.

You have just performed a cpm analysis and have found that more than one path through the project network has zero slack values.
Alex787 [66]

Answer:

There are multiple critical paths

Explanation:

The critical path method (CPM), or critical path analysis (CPA), is an algorithm for scheduling a set of project activities. It is commonly used in conjunction with the program evaluation and review technique (PERT). A critical path is determined by identifying the longest stretch of dependent activities and measuring the time required to complete them from start to finish.

The essential technique for using CPM is to construct a model of the project that includes the following:

  •    A list of all activities required to complete the project (typically categorized within a work breakdown structure),
  •    The time (duration) that each activity will take to complete,
  •    The dependencies between the activities and,
  •    Logical end points such as milestones or deliverable items.      

Using these values, CPM calculates the longest path of planned activities to logical end points or to the end of the project, and the earliest and latest that each activity can start and finish without making the project longer. This process determines which activities are "critical" (i.e., on the longest path) and which have "total float" (i.e., can be delayed without making the project longer).

considering the above function of the cpm analysis because you have multiple path, there is tendency that more than path through the project network will have zero slack values.
