How to Input String in Java

import java.util.Scanner; // Import the Scanner class

public class LAb1 {

public static void main(String[] args) {

String name ;

Scanner input = new Scanner(System.in);// Create Scanner object

System.out.println("Enter your name:" );// Read user input

   name = input.nextLine();// Output user input

}
}

Exercise Chapter7 : Vectors

VECTORS AND SCALARS: BASIC CONCEPTS Exercise 7.2 Solution : 1. For the arbitrary points A, B, C, D and E, and a single vector which is equivalent to A: DC + CB = DB B: CE + DC = DE 2. shows a cube. Let p = AB, q = AD and r = AE . Express the vectors representing BD, AC and AG in terms of p, q and r. Consider the triangle ABD shown in Figure. We note that BD represents the third side of the triangle formed when AD are placed head to tail. Using the triangle law we find : AB + BD = AD => BD = AD - AB = q - p Consider the triangle ADC shown in Figure. We note that AD represe...

Matrix algebra

Matrices provide a means of storing large quantities of information in such a way that each piece can be easily identified and manipulated. They permit the solution of large systems of linear equations to be carried out in a logical and formal way so that computer implementation follows naturally. Applications of matrices extend over many areas of engineering including electrical network analysis and robotics. 1-BASIC DEFINITIONS Matrix is a rectangular pattern or array of numbers. For example: are all matrices. Note that we usually use a capital letter to denote a matrix, and enclose the array of numbers in brackets. To describe the size of a matrix we quote its number of rows and columns in that order so, for example, an r × s matrix has r rows and s colu...
