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

<h2>Explanation:</h2>

The code has been written in Java and it contains comments explaining important parts of the code. Kindly go through the comments.

Westkost [7]

Answer:

802.11ac

Explanation:

It is a wireless networking standard.It functions only on 5 Ghz only. 802.11ac has three times the bandwidth of 802.11n hence it can handle more number of users.It has multi-link throughput of 1 gigabit per second.It provides high throughput.It is very useful for environments with high user density.

Write a method transpose, that takes as argument a 2D array of integers, myTable, and returns the transpose of myTable. The tran

Gelneren [198K]

Answer:

The program to this question can be given as:

Program:

import java.util.*; //import package

public class Main //defining class

{

public static int[][] transpose(int[][] a1) //defining function transpose

{

int i,j; //define variables

int[][] transpose = new int[a1[0].length][a1.length]; //define variable transpose.

//loop for transpose matrix.

for(i = 0; i < a1.length; i++)

{

for(j = 0; j < a1[i].length; j++)

{

transpose [j][i] = a1[i][j]; //hold value in transpose variable

}

return transpose ; //return transpose matrix.

}

public static void main(String[] args) //main method.

{

int row,col,i,j; //defining variable.

Scanner obj = new Scanner(System.in); //creating Scanner class Object

System.out.print("Enter number of rows: ");//message

row = obj.nextInt(); //input rows form user.

System.out.print("Enter number of columns: ");//message

col = obj.nextInt(); //input columns form user.

int[][] a1 = new int[row][col]; //defining array.

System.out.println("Enter matrix"); //message

// loop for input array elements from user

for(i=0; i<a1.length;i++)

{

for(j=0; j<a1[i].length;j++)

{

a1[i][j]=obj.nextInt(); //input in array variable.

}

System.out.println("Matrix you insert :"); //message

// loop for display array.

for(i=0; i<a1.length;i++)

{

for(j=0; j<a1[i].length;j++)

{

System.out.print(a1[i][j]+" "); //print matrix

}

System.out.print("\n");

}

int[][] result = transpose(a1); //define result array variable that holds function value.

System.out.println("Transposed matrix is :");

//use loop for print Transpose matrix.

for(i = 0;i < result.length;i++)

{

for (j = 0; j < result[i].length;j++)

{

System.out.print(result[i][j] + " "); //print matrix

}

System.out.print("\n");

}

Output:

Enter number of rows: 2

Enter number of columns: 3

Enter matrix

2

3

4

9

8

7

Matrix you insert :

2 3 4

9 8 7

Transposed matrix is :

2 9

3 8

4 7

Explanation:

The description of the above program can be given as:

In the above program firstly import a package, then declare a class that is "Main" inside a class defining a transpose() function this function returns a matrix in transpose form.
In the main class, we define a variable and matrix that is "row, col, i, j and a1[][]". Then we Creating a scanner class object, which is used by row, col and a1[][] variables for user input.
The row and col variables are used to declare matrix size and i, j variable is used in the loop for insert and display matrix.
a1[][] matrix is used for input matrix elements and passes into transpose() function as an argument that returns a value that is held in the result variable. This is used as a loop for the print transpose matrix.
